As an innovative brand, we have to be at

least one step ahead of the world’s speeding

high-tech revolutions. Focusing on new devel-

opments, we feel obliged to solve problems

before they even arise – for the well being of

our customers.

In 2006, Norit ‘leading in purification’ was

able to grow substantially and introduced

a large number of new products and applica-

tions to our valued customers around the

world. In this edition of KnowHow, we

would like to familiarize you with some of

these innovations and developments.

We are continuously looking for opportuni-

ties to expand our product portfolio. The

pumps of Nijhuis rank among the worlds best

and we are proud that Nijhuis is now fully

incorporated in our Process Technology

division. The South-to-North Water Diversion

Project is a great example of our joint capa-

bilities.

One of our obligations is also to protect

our planet against pollution. Our Activated

Carbon division has successfully introduced a

solution to remove mercury from the exhaust

gas of power plants before it’s released into

the atmosphere.

Another example is our solution to treat

leachate from landfill sites with our famous

Norit Membrane BioReactor (MBR) technolo-

gy in combination with Norit ultrafiltration,

nanofiltration and activated carbon. Together

with a Turkish partner for the required civil

work, Norit Membrane Technology delivered

a turnkey solution for a landfill in Istanbul.

We have developed this unique and ground-

breaking solution to treat the highly con-

taminated (both organic and inorganic

components) leaking water from landfills

meeting the very challenging EU regulations.

A solution for a problem, which is becoming

bigger all over the world and for which we

offer a safe and reliable solution!

The brewing and beverage industry is also

asking for innovations allowing them to cope

with the growing demand to produce a

high quality product against the lowest total

cost of ownership. Our recently introduced

“brewery of the future” concept meets

today’s criteria to utilize less space and

dramatically reduce the consumption of raw

materials, energy and water and meet the

lowest possible benchmarks in the industry.

All state-of-the-art technologies and exten-

sive know how about brewing from Haffmans,

Südmo and Norit are combined into the most

advanced brewery in the world, a true exam-

ple of Norit ‘leading in purification’.

In case one of our innovations are of interest

to you, please contact one of our motivated

employees around the world. In case you

feel we could help you solving one of your

challenges, we are looking forward to

receive your inquiry and please remember:

CEO Norit NV


Nijhuis uses an in-house developed design

software, called Turbo-Pro, which is suppor-

ted by advanced flow simulation and strength

analysis software. Engineers can use it not

only to design pumps hydraulically, but also

to completely analyse products before manu-

facturing. This guarantees clients a pump that

meets the specifications required and attains

highest possible efficient performance for

the specific applications. Installing a pump

designed in this manner guarantees that

the simulation beforehand and the actual

performance correspond accurately.

Schuuring continues: “Nijhuis pumps espe-

cially excel in high efficiency values. We like

to show our clients that the long-term cost-

efficiency of Nijhuis’ pumps is such that

they will save considerably on their annual

energy costs. And this is how we differentiate

ourselves from the competition.”

All manufactured pumps or scale models

thereof are tested by Nijhuis on a fully

automated test rig on its own premises. This

means that any deviations will be found

quickly and eliminated before the pump is

installed at the client’s site. Nijhuis pumps

have a very diverse range of applications.

Besides supplying pumps and servicing them,

Nijhuis is also active in the field of fire fight-

ing. Our product range includes firefighting

units that consist of a pump, engine and

control unit, all built and assembled at

Nijhuis. These fire fighting units can be used

in many areas, from large buildings to the oil,

gas and petrochemical industry.

“In our collaboration with Norit, we are

mainly concentrating on the areas of drink-

ing-water supply, sewage treatment, desali-

nation plants and industrial applications,’

concludes Schuuring. ‘Just like all of Norit’s

different business units, Nijhuis is a reputable

enterprise with an innovative character

and high-quality products. This similarity, as

well as the fact that several synergetic projects

are being carried out within the Norit group,

is the foundation of a productive collabora-

tion. Therefore, Nijhuis is proud to be a part

of Norit ‘leading in purification’.”

Gold

Gold has long been considered one of the most pre-

cious metals, as it is relatively scarce and occurs in

many different kind of rocks and in many different

geological environments. Due to its rarity and dura-

bility, gold is mainly used as a method of payment

and to make jewelry.

Gold prices were pushed up in 2005-06 and are

expected to increase further in 2007-08, reflecting

continued global uncertainty and gold’s use as a

store of value. The optimistic outlook for gold is

responsible for a lot of activity in the gold mining

industry; smaller operations are acquired by larger

companies and many new plants are constructed.

The process of producing gold can

be divided in to six main phases:

1. finding the ore body

2. creating access to the ore body

3. removing the ore by mining

4. transporting the broken material to the

plants for treatment

5. processing of the ore

6. refining of the ore

Norit activated carbon plays an important

role in the gold recovery industry

About 2600 tons of gold are mined from the earth

per annum, predominantly extracted via processes

where activated carbon is used in the concentration

step. Gold in the ore pulp is extracted with aqueous

alkaline cyanide and dissolves into a gold-cyanide

complex. Activated carbon adsorbs the gold-cyanide

complex from the slurry and is then removed by

screening.

Reviewing all steps in a gold recovery process, the

ideal carbon exhibits the following product charac-

teristics:

• high attrition resistance

• fast speed of adsorption

• high fouling resistance

• minimized pre-conditioning loss

• minimal screen pegging

• high gold loading capacity

For the gold recovery industry, Norit especially

developed a unique cylindrically shaped acti-

vated carbon, type Norit RO 3515/3520. This

type demonstrated a significant better perfor-

mance and it is currently used at various gold

operations worldwide as e.g. Anglogold in

South Africa and Australia. Recently, the bene-

fits of Norit activated carbon were discovered in

China, resulting in regular supplies to this fast

growing economy.

Numbers applicable for a high grade gold mine:

• head grade:

5 g Au/t – 10 g Au/ton ore

• carbon consumption:

10 – 40 g/ton ore

• cyanide consumption:

400 – 500 g/ton ore

• steel balls:

800 – 1200 g/ton ore

• lime:

1200 – 1500 g/ton ore

• gold recovery rate:

85 – 95 %

The net result for an average gold operation,

with a higher gold yield and a lower consump-

tion of Norit activated carbon, is in the order

of USD 500.000 annually. Therefore choosing

for Norit is a way to increase your process

performance with lower operational cost.

Further applications of Norit activated

carbon in the mining industry

In addition to mining gold, Norit activated

carbon can be used as a purifying and decolor-

izing agent in a wide range of processes to

benefit the efficiency and performance of all

types of mine operations, such as:

• water treatment and purification

(process and waste water),

e.g. micro-pollutant removal

• removal of flotation reagents, e.g. in multiple

flotation processes (copper, platinum, zinc,

molybdenum)

• gas and air purification e.g. the removal of

mercury in the vapor phase.

Norit has a long history in the mining industry

using for example activated carbon in the

extraction process of gold. Learning from the

challenges in this industry, Norit now also applies

their X-Flow membranes for treating the Acid

Mine Drainage Water.

Norit ‘leading in purification’ in the mining industry

Next to activated carbon, Norit X-Flow mem-

brane filtration technology is used for different

water treatment applications in mining opera-

tions. An important application is the treatment

of Acid Mine Drainage Water.

Acid mine drainage (AMD) water arising from

the coal, gold, uranium and platinum mines is

a major threat to the environment, but on the

other hand constitutes a major resource for

the production of high quality drinking water

through the process of desalination. All desali-

nation processes co-produce process water as

well as a more concentrated brine effluent.

The economic potential use for desalination at

inland sites necessitates that the brine effluent

volume should be minimized so that final

disposal costs through solar or mechanical

evaporation can be as low as possible.

AquaflexTM membranes – state-of-the-art

water treatment for the mining industry

Keyplan has developed the High Recovery

Precipitation Reverse Osmosis (HiPRO®) process

that significantly outperforms any comparable

technology for the treatment of AMD. This

high-tech process has been successfully demon-

strated at Anglo Coal’s Landau Colliery in South-

Africa, where water with high acidity and high

sulfate concentration is transformed into

superior quality drinking water. What sets this

process apart from other technologies is the

high water recovery of 97% based on the feed

volume. In order to achieve this, the process

utilizes multiple stages of ultrafiltration (UF)

and reverse osmosis (RO) membrane systems

operating in series and with interstage preci-

pitation of low solubility salts. This means that

only 3% of the raw feed water remains for

disposal to a lined evaporation dam!

The heart of the HiPRO® process is a Ultra-

filtration/Reverse Osmosis (UF/RO) plant which

is used to concentrate the water to produce

supersaturated brine from which sparingly

soluble salts such as calcium sulphate and

calcium carbonate can be precipitated.

Key to the success of the process is a UF system

which can tolerate the operating conditions

imposed on it. Several membrane types and

configurations were tested in a 15 month

demonstration run. The Norit X-Flow AquaflexTM

membrane proved highly successful and was

able to operate for months before cleaning

was required. Thus, X-Flow was awarded an

order for over 500 AquaflexTM 40m2 elements

for installation in the Emalahleni 24Ml/d

Mine Water Reclamation Plant in South-Africa

currently being constructed by Keyplan for

the Anglo American – BHP Billiton joint venture.

The UF plant will be commissioned in May

2007.

The AquaflexTM concept is a flexible system con-

struction, which is easily expandable. With our

standard AquaflexTM endcaps, the modules are

connected to the piping of the installation. The

process is operated in dead-end. Airflush® can

be used in AquaflexTM concept to ensure a very

efficient way of cleaning, resulting in reduced

chemical consumption and long term stable

operation. The design of the module ensures

effective and even distribution of water over

the entire length of the module as well as an

extremely efficient backwash.

CO2 Management

Whilst often not regarded as such on first

sight, carbon dioxide (CO2) is referred to as

the 5th ingredient of beer, next to the key

ingredients water, hop, malt and yeast. It is

important to the quality and taste of beer

and the same applies to soft drinks. A reliable

CO2 management is therefore an important

aspect in beverage production.

Over the years, Haffmans has continuously

advanced its CO2 measurement, which is

based on Henry’s Law. Today, it is well respect-

ed and adapted as standard by a large number

of customers all around the globe as a trusted

measurement contributing to the high quality

production processes. However, Haffmans not

only takes care of quality control and quality

assurance aspects with regard to CO2, but

is also well known for its CO2 recovery and

carbonation technology. Through the years,

Haffmans established itself as the “ono-stop-

shop” for total CO2 management in the market.

O2 Management

Next to CO2, a second gas of major importance

in the beverage industry is oxygen (O2).

As O2 is highly detrimental to beverages,

because of its negative effects on both

shelf life and flavor stability, measuring the

O2 content in beer and beverages is an essen-

tial quality control aspect during and after

production. Nowadays, the nearly indefinite

choices of flavors and the use of ever more

sensitive ingredients require lowest oxygen

level in beverages. With the development

of a new and unique optical measurement

technology, Haffmans designed a series of

O2 measurement devices closely responding

to the needs of the market. Compared to

traditional dissolved O2 measurement tech-

nology, the new method excels through

higher response times, highest accuracy at

even lowest oxygen levels and long-term

stability. By adding this unique measurement

to the product range, together with the

purification of CO2 recovered from fermenta-

tion and the deaeration of water, Haffmans

is now able to offer a Total O2 Management

to the market.

Total CO2 and O2 Management

Haffmans covers every aspect of CO2 and O2

management in brewing and beverage

production:

• CO2 and O2 control in CO2 gas from recovery

• water deaeration

• carbonation and ‘bubble-free’ dissolving

of CO2 in liquid

• in-line and at-line CO2 and O2 control and

measurement during various production

steps

• measurement of CO2 and O2 in the final

product, filled in bottles, cans or kegs

Norit Haffmans is renown as a reliable supplier of quality control equipment and CO2 systems

in the brewing and beverage industry. Next to covering a wide range of quality control aspects

including foam & turbidity measurement and monitoring of processes such as pasteurization

or keg and bottle washing, one of Haffmans’ focus areas is CO2 and O2 management. With

new market developments, O2 is becoming an increasingly significant factor.

Total CO2 and O2 Management In May 2006, Bavaria contacted Norit

Components & Services BV, who are respon-

sible for Südmo Components sales in the

Benelux, and requested an offer for the sup-

ply of valves/matrices for the expansion of the

clear beer cellar. From the very beginning of

the project, the cooperation proved to be

very close.

Bavaria had a series of requirements to be

met by suppliers of double seat, leak proof

valve technology.

State-of-the-art valve technology

Following their introduction in 1995, Südmo

now has over 50,000 leak proof valves in ser-

vice. The Südmo D6XX series double seat

valves are therefore thoroughly used and

tested and have proven themselves in many

varied applications.

Sturdy build

Südmo manufactures all valves from solid

stainless steel. The bodies are not pressed

from stainless steel plates and welded to-

gether.

Depending on the valve size, the valve bodies

are produced out of solid round stock

and machined to a wall thicknesses of about

6 mm.

Flexible valve options

Initially, Bavaria left the double seat valve

configuration up to the supplier. For Südmo

this meant that all possibilities were supplied

with argumentation. From double seat valves

with seat lifting to valves with external valve

flushing and from low-leakage to leakage-

free switching valves. In the end, Bavaria

selected the Südmo D630 with external flush-

ing and a leakage-free switching design.

Intelligent control top

Südmo has its own intelligent control top, the

IntelliTop, which is fitted with an AS Interface

module in this project.

Professional solutions for

closed leakage collection

This element was extremely important to

Bavaria. It is essential that its clear beer cellar

remains dry, which meant an extra challenge

for our valve engineers. Every valve in the

manifold is fitted with a transparent leakage

drain hose that forms a flexible connection to

the central drain hub. This avoids spillage and

the needs for frequent wash downs in the

tank cellar room. One of the challenges in

making this closed construction is to enable

visual leakage detectable. Norit’s engineering

department came up with a practical solu-

tion, simply collecting and allowing obser-

vation of any discharge per valve in an

assembly.

Good references in the beer market

Together with Bavaria specialists, Südmo

visited several breweries where Südmo valve

matrices are applied in similar beer applica-

tions.

Delivery time guarantee

The pressure tank cellar expansion project

was on a tight schedule. Südmo kept to

schedule and delivered the valves/matrices in

Lieshout on 20 December 2006.

Norit Americas has been deeply involved in

the development of technology for mercury

removal in the US coal-fired utility market

over the last five years. Norit activated carbon

has been utilized in over thirty commercial

full-scale demonstrations of activated carbon

for mercury removal in a wide variety of fuels

and configurations. Norit activated carbon,

including DARCO Hg and Norit GL 50 are

recognized as the industry standard by

which all other activated carbons are meas-

ured. Today, Norit activated carbon effectively

removes 70 to 95% of the mercury in the

flue gas.

Norit is continuing to develop higher per-

formance activated carbon for the removal

of mercury. This development work has led to

new products, such as DARCO Hg-LH, which

uses the addition of bromines to enhance

the performance in certain applications.

Currently, Norit is working to develop a

high performance activated carbon for high

SO3 applications.

Additionally, together with technology and

industry groups, Norit Activated Carbon has

spent the last year in development of a

revolutionary new means of assessing the

quality of Activated Carbon for mercury

removal – the Mercury Index. As a quality

control method, we will actually be testing

each lot for its ability to remove mercury,

ensuring end-user performance and satisfac-

tion. As a research tool, it will allow Norit to

remain on the leading edge of technology.

Norit has secured the first commercial

contracts for supply of activated carbon

to the early adopters of this technology.

Our activated carbon technology and the

extensive experience in supply of activated

carbon handling equipment positions Norit

well for the long term as this new market

develops.

The majority of electricity generation in North America is the result of burning coal. US coal

fired utilities contribute 48 tons per year of mercury contamination into the environment.

Mercury settles into our water systems, and when consumed by fish, becomes a ready

metabolizable form of mercury (methyl-mercury). This form can affect pregnant mothers

and the development of children. In March 2005, U.S. federal regulations for control of

mercury from coal-fired utilities were issued with effective dates ranging from 2010 to 2018.

In Canada, regulations for coal-fired utilities become effective in 2010.

For over 20 years, flue gas from municipal

waste combustors has been regulated for

mercury in the United States. The combustion

of municipal waste had long been recognized

as a significant source of mercury as broken

thermometers, thermostats and many other

household items containing mercury are

disposed in municipal waste. The best availa-

ble control technology for mercury removal

was determined to be dry activated carbon

injection into the flue gas ahead of the

particulate matter control device located

at the plant. The mercury is adsorbed by

the activated carbon and subsequently col-

lected in the particulate control device. Norit

has led the technology for this market since

its inception.

There are roughly 1150 coal fired electrical

generation units in the United States (versus

about 50 municipal waste plants). Each unit

has its own unique combination of boiler

type, fuel source(s), and pollution control

equipment (sulfur scrubbing, nitrogen oxides

reduction, and particulate control). This

provides a highly variable chemistry in the

flue gas, which makes for a challenging

environment to remove mercury. As in the

In the last century, a chronic water shortage

has arisen in the north of China. Due to an

increase in the population’s water consump-

tion and the shifting of river courses in the

mid 20th century, the groundwater level has

sunk from 5 meters to 80 meters below-

ground level, a situation that has led to

many problems. The south of China is coping

with an overabundance of water, while

people in the north suffer shortages. Rivers

in China mainly flow from west to east

and do not provide the possibility to trans-

port water from the south to the north, a

situation which former Chinese leader Mao

had already recognized in 1954 as one that

would need to be changed. In December

2002, the Chinese government ultimately

decided to initiate a project costing billions,

called the South-to-North Water Diversion

Project.

The project involves the realization of three

linking canals with a total length of around

2,500 km between the Yangtze River in the

south and the Yellow river in the north,

straight through several Chinese provinces.

The project will take 50 years to complete

and is divided into a number of smaller parts.

The most easterly link consists of around

30 pumping stations and it will be the first

to be completed in 2010.

Nijhuis has been involved in the plans as advi-

sor since 2002. The basis for the advice was

the bulb pumps project for pumping station

IJmuiden in the Netherlands. This type of

high-efficiency pump would suit the applica-

tion well in China. In 2005, everything gained

momentum because the tenders were going

to hit the market in 2006. In order to make

further contacts, Nijhuis went to the Shandong

province as a member of a delegation of com-

panies from the east of The Netherlands.

Additionally, Nijhuis was part of a delegation

of 25 Dutch companies that visited China

along with State Secretary Schultz van Haegen

in May of 2006.

To keep ahead of the competition, Nijhuis

started its search for a suitable strategic

partner in China. They found one in Changsa

Pumps, an enterprise which was later

merged with engine supplier XEMC, with

whom an exclusive agreement was signed for

the tender of the eastern part of the project.

During Nijhuis’ talks in China, the focus of the

project in this province was on a conventional

pump with a slip-ring rotor motor. All efforts

were rewarded with one order for Nijhuis/

XEMC and the possibility to supply six more

pumping stations with propeller pumps.

This also resulted in obtaining a subsidy

from “Partners for Water”, a programme for

innovative water projects by collaborating

partners abroad, initiated by the Dutch

government.

Nijhuis Pompen BV will be supplying pumps

to a prestigious project in China: the South-

to-North Water Diversion Project.

Nijhuis is responsible for the design, construc-

Given the large number of breweries that already

decided to look for an alternative to kieselguhr, Beer

Membrane Filtration is not longer an alternative but

a proven technology to filter a large variety of differ-

ent beer types. During the Brau Beviale, Norit passed

a new milestone of filtering more than 20 million hl

of beer with the current BMF systems in Germany,

Poland, Spain, Czech Republic, South Africa and

Japan. Dick Meyer, Norit Process Technology, points

out: ”The true leadership of Norit is also reflected in

our concept for the ‘brewery of the future‘. In 2007

Norit will commission two breweries with a capacity

of 3 million hl of beer each where the advantages of

membrane technology both in Beer Membrane

Filtration and re-use of wastewater are optimally

utilized.

True advantages, such as that the investment costs

are not only below € 10 per hl (excluding packaging

equipment, but including tanks and civils for brew-

house and cellars), guarantee a high quality product

against the lowest operational cost in the world,

with, for example, a typical water consumption of

1,5 – 1,7 hl of water for 1,0 hl of beer and 1,0 FTE

per shift. It’s obvious that brewers, not only from

emerging markets but also from all over the world,

showed tremendous interest in our concept.”

Menno M. Holterman, Board Member of Norit and

responsible for the organization of Brau Beviale 2006

concludes: “This year Norit has shown its value and

strength as a group again. This exhibition perfectly

reflects the synergies and benefits

for our customers around the world.

Generally, customers showed respect

for the achievements of our group

and interest in our key-technologies,

underlining that Norit today is ‘lead-

ing in purification‘.”

Brau Beviale 2006 – a great successMore than 36,000 people visited the Brau Beviale, the most important exhibition for the brewing

and beverage industry in 2006. Norit ‘leading in purification’ used this important event to exhibit

its latest key-technologies for brewing, beverage manufacturing and water treatment.

René Kuipers, CEO Norit, was very pleased

with the course of the exhibition: “As Drinktec

in Munich provided a lot of orders and

exposure to Norit, we are very pleased with the

number of visitors and decision makers who

visited our booth and spent time with our

motivated team to become updated on the

latest innovations. Furthermore, Brau Beviale

is getting more international, which was

reflected this year by the large number of

visitors from Central, Middle and Eastern

Europe, as well as from Russia, Ukraine and

Central and Latin America. Being active in over

150 countries around the world, Norit ‘leading

in purification’ welcomes these positive devel-

opments!”

It became clear that water is a hot topic in the

brewing and beverage industry. Water is not

only one of the irreplaceable ingredients for

a tasty beer or beverage, but also an ingredient,

which is becoming more scarce and expensive.

Norit presented a long list of references using

its proven UF (XIGA) and MBR (Aquaflex) tech-

nology.

Ronny Konink, Norit Membrane Technology,

explains: “Since Norit successfully installed ref-

erences for reuse of (waste)water in breweries,

beverage production plants and malteries, we

have received a large and growing number of

inquiries for our proven Membrane BioReactor

(MBR) technology, often in combination with

Norit activated carbon, literally from customers

located all over the world. The large customer

base of Norit Activated Carbon, Haffmans and

Südmo in brewing and beverage is a great help

to roll-out our unique technologies around the

world”.

Norit not only focuses on the design and deliv-

ery of municipal and industrial water treatment

plants but also delivers point-of-use systems.

Dennis Nahuijsen, Filtrix, explains: “Beverage

manufacturers put a lot of effort and costs

into the production of high quality syrup. Poor

water quality can easily destroy the flavor of

beverages, leaving the consumers with a

negative experience. Filtrix’ compact LineGuard

system guarantees safe, bacteria and odor-free

water for post-mix dispensers“.

Most importantly, the new corporate identity

of Norit is helping customers to understand

and benefit from the key-technologies Norit is

offering to the global brewing and beverage

industry. Wim Plaisier, Südmo Components,

explains: “This year‘s highly qualified visitors

and decision makers were all very impressed

by our joint presentation and group capabili-

ties. Everyone recognized Norit ‘leading in

purification’ as a serious partner providing

high quality solutions to the water and

beverage industry.” Südmo recently started to

promote the different Norit technologies for

water treatment in Germany. Especially the

capabilities of Südmo to deliver turnkey

solutions for beverage and mineral water

manufacturing are highly appreciated given

the healthy order books for 2007.

Haffmans used the Brau Beviale 2006 to intro-

duce their new In-line O2 Gehaltemeter (OGM)

as well as their new low-cost Carbo Controller

(CCR). Frank Verkoelen, Haffmans, reflects:

“Customers showed a great interest in our revo-

lutionary method to measure dissolved oxygen,

both in combination with our proven CO2 meas-

urement as well as our newly introduced

single O2 measurement. The latter will satisfy

the growing needs of our global customers

to solve problems with existing measuring

technologies. Next to Quality Control for both

laboratory and in-line applications, Haffmans

was able to close orders for their CO2-Recovery

Technology, which underlines our leadership

in Total CO2/O2 Management.”

Norit Synergy AwardThe winners of the prestigious Norit

Synergy Award for the first quarter in

2007 are Joost Jacobs (Commercial

Director) and Henk Schonewille (Area

Sales Manager) from Norit Membrane

Technology for the successful intro-

duction of the Norit leachate water

treatment technology for landfills.

“The market for landfill water treatment

is growing fast, especially in Europe and

surrounding countries like Turkey,”

explains Joost Jacobs. “Norit Membrane

Technology combines Norit’s competences

in water with Norit’s key-technologies,

such as our outperforming Membrane

BioReactor, ultrafiltration, nanofiltration

and activated carbon treatment into a

unique and unbeatable solution. By these

means, we are able to turn highly

polluted leachate water from landfills

into a water quality suitable for discharge

and/or re-use e.g. process water or irriga-

tion water.”

Henk Schonewille continues: “The current

project in Istanbul is a great reference

both for our European and Asian

customers. We received a lot of inquiries

from landfill operators who need to

invest in order to cope with severe

regulations set by their governments

and the EU.”

Norit Membrane Technology BV is actually

building two of Europe’s largest membrane

plants for the treatment of percolate water

in Istanbul, Turkey. Norit developed a unique

and technologically groundbreaking solution

for a problem that is becoming bigger all over

the world: leakage water from solid waste

landfills (leachate). Both plants will have a

total capacity of 5,000 m3 per day and will be

operational in 2007.

Leachate treatment in general and the

perspectives of Membrane BioReactor and

Nanofiltration technology

Leachate from landfill sites can be a problem

predominantly for countries in Eastern and

Southern Europe joining or willing to join the

EU - meaning that they will be bound by tight

EU regulations. Collecting household solid

waste and dumping it on landfills results in

the production of leakage water. The water

that leaks out of the dump is called leachate,

and is seriously contaminated with organic

and inorganic components.

The choice of the leachate treatment system

depends on the standards to meet for the

receiving surface water. In general, the

self-purification capacity is insufficient for

concentrated discharges and therefore

treatment in a WWTP or biological leachate

treatment plant has to reduce oxygen con-

sumption of the leachate (BOD removal and

nitrification). In case of discharge to more

critical receiving water (oligotrophic lakes)

denitrification and phosphorous removal is

necessary. For both an MBR is technically and

economically the most efficient solution.

The next step is removal of color, heavy

metals and organic micro pollutants (PAH,

EOX etc.) by nanofiltration and/or activated

carbon systems. If the receiving water cannot

dilute the salt content in a proper way and

is used for agricultural purposes (cattle

water, irrigation) or is a source for potable

water, desalination of the leachate can be

necessary by e.g. reverse osmosis, electro-

dialysis or evaporation.

The Istanbul landfills of ISTAÇ

ISTAÇ Co., Istanbul Metropolitan Municipality

Environmental Protection and Waste Materials

Valuation Industry and Trade Co., is one

of the Economic Enterprises of Istanbul

Metropolitan Municipality.

As the name denotes, ISTAÇ Co. within the

scope of Solid Waste Project of Istanbul

Metropolitan Municipality, provides services

for transportation of solid waste, production

of compost fertilizer, recycling of waste, dis-

posal of waste via regulated storing, electric

energy generation from landfills, transporta-

tion of medical waste and their disposal via

incineration.

On the European side 8,000 tons of garbage

are being collected daily in the landfill area

established on 75 hectares in Odayeri/

Göktürk’teki. Nowadays 2,000 m3/day of lea-

chate is produced and in the future this will

be 3,000 m3/day.

On the Anatolian side 4,000 tons of garbage

are being collected daily in landfill area in

Kömürcüoda/Karakiraz Village, and an area

of 100 hectares is used for this work. Nowadays

1,200 m3/day of leachate is produced and in

the future this will be 2,000 m3/day.

The project

In 2006 the project for the treatment of

leachate for the two Istanbul landfills was

awarded to Norit Membrane Technology.

In 2007 the leachate treatment plants from

the two main landfills in Istanbul, one at

the European (Oyaderi) and one at the Asian

(Kömüorcüoda) side of the city, will be exe-

cuted with a Norit Membrane BioReactor

system (MBR) followed by a Norit Nanofiltra-

tion system (NF) with post treatment by acti-

vated carbon (AC). The concentrate of the

nanofiltration system will be treated on the

landfill site and the salty permeate will be

discharged in the seawater of the Bosporus.

In 2007 two major leachate water treatment

plants - with the use of a Membrane

BioReactor (MBR) followed by Nanofiltration

(NF) - will be implemented in Istanbul,

Turkey.

Norit Membrane Technology BV offers complete solution for global problem

The wastewater treatment plants in Istanbul

will use a combination of several different

Norit Group purification solutions: a biologi-

cal process applied in conjunction with

ultrafiltration, followed by nanofiltration

and Norit activated carbon filtration. Norit

Membrane Technology develops this turnkey

project in cooperation with a civilian partner

in Turkey. In addition, Norit will be responsi-

ble for plant operation during the initial

years.

The leachate treatment plant consists of the

following process stages:

1. Leachate intake

2. Membrane BioReactor (Norit Crossflow

MBR), consisting of:

• Oxic/Anoxic bioreactor

• Norit Crossflow Ultrafiltration plant

3. Sludge treatment

4. Norit Nanofiltration installation

5. Norit Activated Carbon filtration

6. Effluent discharge

Project Progress January 2007

After the contract was awarded, the Norit

project team started directly with a detailed

site investigation in order to create a good

basis for the start of the design and engineer-

ing of the new leachate treatment plants

for both the European and the Asian site.

In August the final design and engineering

package was ready and the Turkish consorti-

um partner HAMLE Insaat started construc-

tion works on site.

On the European site, this impressive job - as

a bioreactor is actually a concrete basin with

a depth of six meter and the size of a football

pitch - was finished in mid December 2006.

Directly after that, Norit delivered all equip-

ment to the site and started installing

the UF-skids, NF-skids, aerators, pumps, dos-

ing cabinets, electrical panels and others.

Interconnecting piping and cabling was

installed by the end of February 2007. After

that the three-month long commissioning

phase started.

The Asian site is running 3 months behind

the European site. Reason for this is the

extensive piling needed for the construction

works due to the soil condition; 1,500 con-

crete piles have been drilled into the ground

in order to create a solid base for the bioreac-

tor and building.

Overall winner Norit Synergy Award 2006: ‘Brewery of the future’ concept

In 2006 Norit initiated the “Norit Synergy

Award”. Every quarter the best example

of synergy and cooperation is chosen to go

forward and compete for the annual Norit

Synergy Award.

The Board of Norit has decided to award

the Norit ‘Brewery of the future’ concept,

winner of the fourth quarter, as the overall

winner of 2006. All know-how, experience

and state-of-the-art technologies from

Haffmans, Südmo and Norit are combined

in the most advanced brewery concept

of the world, meeting today’s highest

quality standards, economical and environ-

mental requirements. A true example of Norit

‘leading in purification’!

Dick Meijer, Commercial Director Beverage of

Norit Process Technology proudly explains,

“Winning this prestigious award does not

only mean a lot to me personally but to the

entire Norit team as well, as it is a direct

acknowledgement of the hard work and

efforts taken over the last years to develop

this revolutionary concept.”

At the start of this challenging project we

analyzed today’s customer requirements:

• Today’s brewing requirements: highest

and consistent beer quality

• Today’s environmental requirements:

minimize disposals (no kieselguhr), mini-

mize consumption of utilities, maximize

utilization of capacity and reduce losses

• Today’s economical requirements: increas-

ing competitive landscape, strong influ-

ence of marketing pushing production

for increasing flexibility, decreasing

logistical cost, minimize cost for con-

sumption of raw materials, utilities and

maintenance and “cash is king”

These requirements are all translated into

our ‘Brewery of the future’ concept. The most

important step is the shift from batch to

continuous beer processing, utilizing the

benefits of continuous beer filtration with

our environmental friendly BMF technology.

Capacity is increased by 40%, beer losses

are reduced to below 1%, beer stability is

improved and less beer storage is required.

Südmo valves and process know-how is

utilized to improve the hygienic design and

increased level of automation. Due to the

compact design, smaller equipment is utilized

consuming less energy and requiring a lower

capital expenditure (CAPEX).”

Dick Meijer continues: “The permanent strive

to lower the operational expenditure (OPEX)

is realized by a dramatic reduction of the

water consumption from traditionally 3 – 4 hl

to almost 2 hl water for 1 hl beer. By using

Norit’s Membrane BioReactor technology

(MBR) wastewater is treated and can be

re-used as process water. Balancing heating

and cooling requirements during the brewing

process results in a substantial reduction

of the energy consumption. Haffmans Total

CO2 Management philosophy is implemented

to maximize the recovery and re-use of CO2

as well as to minimize the energy consump-

tion during the CO2 recovery process. The

entire brewing process is controlled by

Haffmans quality control equipment, both

in-line as well as in the laboratory, finding

a competitive balance between quality

control requirements and cost of operation.

A high level of automation guarantees a

high level of productivity. Manpower is

minimized as well: Every shift requires only

two operators for beer processing, six for

bottling and one for utilities and mainte-

nance.“

“Today, quality and consistency matter to

brewers more than ever. The combined

brewing know-how and state-of-the-art

technologies within the Norit group guaran-

tee highest quality and consistency. Dick

Meijer resumes: “Money talks, our concept

requires a CAPEX of around € 10 for every hl

to be installed, including civil work and

excluding packaging with an OPEX of around

€ 2 per hl for the brewing part!”

In 2007, Norit Process Technology will start-up

at least two Greenfield operations based on

this revolutionary ‘Brewery of the Future’

concept.

Haffmans wins ’Most Improved Supplier Award’ of SAB Ltd BreweryIn 2006 the Newlands Brewery has been

awarded as the Best Brewery of the year

for the 2nd consecutive year in SAB Ltd. It is

a première in the SAB tradition that the

same brewery wins this highly rated award

for the 2nd consecutive year. One key to

this successful performance is the Supplier

Partnership Program in place.

Emmanuel Rurema, Senior Product Area

Manager at Haffmans BV, responsible for

sales in Africa, Middle East and several

countries in Europe & Asia, explains in details:

”This program consists of a communication

and evaluation system for suppliers, where

both parties (brewery and supplier) discuss

on a quarterly basis issues such as quality,

deliveries, incidents, etc. and evaluate each

other. At the end of the year the brewery

rates all suppliers and nominates the awarded

suppliers during an official function. The

awards are in four categories and are given

by three different departments: Brewing,

Packaging and QC/QA. For the year 2006,

Haffmans has been awarded as the Most

Improved Supplier of the Year for QC/QA by

SAB Newlands brewery.”

The South African market has been a real

challenge for Haffmans as in recent years the

requirements have increased in both ways

qualitatively and quantitatively, and it was

very difficult to find a good local partner.

A study of the best possible partners and

a close consultation with the key customers

has led to a Cape Town based company

named “Eureka Scientific”. Eureka has won

the Best Supplier Award from SAB Newlands

Brewery for the 2nd consecutive year (2005

and 2006). Eureka supplies equipment to

medical-scientific institutions and the bever-

age market. The key to success for Eureka

is the focus on the service supply to the

customer: availability of spare parts and

trouble shooting support.

The partnership between Haffmans and

Eureka quickly turned into a synergy based

on combining Haffmans’ unconditional

product quality, industrial experience and

dedicated area management with Eureka’s

service organization, market know-how

and flexibility to always meet customer

demands.

With the new set-up Haffmans could again

realize significant operational and strategic

results. Sales increased substantially, several

new innovations such as i-DGM, Vos Rota

and Bottle Monitor were successfully tested

and accepted as standards and training

programs were given to SAB operations. Last

but not least, Haffmans has been assigned to

review CO2 recovery plants in all SAB Ltd.

breweries and assist the group in improving

the CO2 supply situation as the current CO2

shortage in South Africa is a major problem

for the regional beverage industry.

“For Haffmans”, concludes Rurema, “is this

award simply a reflection of all efforts

done and performances achieved in the still

continuing journey with one destination: ‘To

supply value instead of only equipment’.”

Norit do Brasil

The office is responsible for the promotion and

sales of activated carbon, ultrafiltration mem-

branes, valves, CO2 systems for carbonation,

blending, deaeration and CO2 recovery and

beer membrane filtration systems. Although

some Norit companies already had a long

and successful history in Brazil, the strategic

decision was made to concentrate the Norit

representation in one office, thus maximizing

the synergy between the group’s companies

on the ground. The fact that Norit do Brasil is

next to Norit Südmo Latin America (NSLA)

already the second Norit representation in Latin

America, reflects the increasing demands of

the market.

Roberto Freire, Country Manager and Managing

Director of NdB, points out: “Our presence in

distinct markets as automotive, gold mining,

food, water, chemical, pharmaceutical, bever-

age, agrochemicals, petrochemical, gas & air,

among others, with products such as activated

carbon and valves, created a strong impulse

force that sped up not only the sales of these

well-known products, but also UF membranes

for effluents and water treatment. The possibili-

ties for the Norit group in Brazil are enormous.

Almost every customer visited for activated car-

bon, valves and membranes so far, showed inter-

est in other innovative Norit solutions as well,

amplifying the effects of synergy we were aim-

ing for.”

Having sold two major water installations within

only few months, one to the paper industry and

another for the sugar mill segment, the office

proved its value already. Roberto Freire contin-

ues: ”After only three months, several partner-

ships with OEMs were established and the first

successful milestone reached: NdB sold two

large water treatment systems: The first to a

major paper industry and the other to a sugar

and alcohol mill, thus covering two of the most

important segments of our national industry.

The valves segment also showed significant

growth with new businesses won at Ambev’s

facilities expansions”.

“Another important factor to be mentioned

is the very productive work that is being

developed together with NSLA, an example was

the recent sale of an MBR ultrafiltration system

by a Brazilian Engineering Company to an

Argentinean Agrochemicals producer, where

NSLA gave full support to us by directly import-

ing the skids and delivering these to the cus-

tomer,” concludes Freire.

Norit Südmo Latin America

In addition to expanding Norit’s representation

to Brazil and as a result of a close cooperation

with Norit Process Technology in Panama, NSLA

extended its commercial operations to Panamá,

Colombia and Ecuador at the beginning of

2005. A second one at the Bavaria brewery of

Barranquilla, located at the Caribbean coast

of Colombia, immediately followed the great

success of the first project executed in Panamá.

Soon, other important orders followed, like the

recent fermentation cellar ordered by Cervecería

Nacional Panamá (SAB Miller Group).

Pedro Ayuso, Country Manager and Managing

Director of NSLA, further enhances the success-

ful expansion: “During the first few projects, we

realized the enormous potential of this region

and especially of its main brewery group, the

Colombian Bavaria, recently acquired by SAB

Miller. This brewing group basically dominates

the beer markets of Panamá, Colombia, Ecuador

and Perú, with an average share clearly above

90%. Moreover, SAB Miller has ambitious plans

for this area. The South African global player

chose this region to consolidate his leading

position in the Latin American market.

Therefore, we decided to focus on the beer

market, where the Norit portfolio gives us an

excellent opportunity of a fast penetration.

The well-known components and units of

Südmo and Haffmans, in combination with

the innovative standard process solutions devel-

oped by our Group, play a central role in our

Over the last couple of years, the Latin American market has become an even more important

market for Norit. In order to meet the requirements of the growing market locally, in December 2005

Norit established a second sales office in this area: Norit do Brasil (NdB), which due to the success

obtained during 2006, was recently expanded and moved to Jundiaí, São Paulo.

Latin America - a growing market Currently, the product is mainly applied in

case of Legionella outbreaks at institutions

and other public centers such as hotels,

sports centers, and schools. In these cases

the ShowerFilter provides an excellent

temporary solution, without having to

close down the institution. Here, the

ShowerFilter serves as a genuine first-aid

measure.

Another application area of the

ShowerFilter are wards with patients

who are immunocompromised by medical

condition or drug therapy, such as bone

marrow or organ transplantation patients

or HIV positives. These patients require

a special, permanent protection against

harmful microorganisms to be found in

the hospital water. Recently, research has

proven that hospital acquired infections

are already the fourth leading cause of

death.

Showers are a major source of transmitting

harmful microorganisms such as Legionella

and Fungi. Here, point-of-use filtration

offers the safest and most affordable solu-

tion. Not only does it provide effective

protection for patients and staff but it

also cuts down costs (shorter patient stay)

and contributes to a better public image

of the hospital.

In order to meet the requirements of the

Health Care market, the ShowerFilter has

recently obtained a CE medical mark that

guarantees the quality of the product.

Furthermore, a recent field evaluation test

of the ShowerFilter has taken place at

the bone marrow transplant ward of the

university hospital St. Radboud in Nijmegen,

The Netherlands, supervised by a hospital

hygiene professor. The results of this test

were extremely positive: The ShowerFilter

proved to be well suited for this particular

purpose and to have a much longer life-

time than competitive products. In short:

the ShowerFilter is ready for the Health

Care market!

Natural waters in Europe

In nature, water shows up in many ways: in

glaciers, vapor, groundwater and surface

water (rivers, lakes, canals, marine waters).

They’re all connected with each other, part of

the hydrological chain. Apart from ecological

aspects, imagine how important water quality

is for human mankind: water for bathing

and recreation, as drinking water source,

transport carrier, and – yes – receptor of dis-

charges! Investigation under the population

has revealed that the quality of natural

waters is one of the main concerns of EU citi-

zens.

The 5th Water Framework Directive (WFD)

The WFD provides an integrated approach

based on management by river basin, being

the key geographical/hydrological unit. Hence,

administrative and national boundaries are

subordinate to this river basin philosophy.

A set of standards has been formulated per-

taining to chemical, ecological and hydrologi-

cal characteristics. Further, a number of stand-

ards shall be developed based on the local

situation, according to a prescribed protocol.

This will also impact the level of treatment of

wastewater being discharged.

The WFD has been formally accepted in

December 2000. A time schedule applies to

all EU nations, including an inventory of

potential problems, setting up a monitoring

network, developing plans and the imple-

mentation of measures, finally by 2015 the

latest. And the public involvement is highly

stimulated in this process!

How Norit Activated Carbon gets involved

Municipal wastewaters are typically treated

by clarification and biological techniques,

focused on removal of suspended solids,

biodegradable organics and nutrients (N, P).

As a result of the WFD based targets, increased

removal efficiencies will be required for

several compounds, including pesticides,

Poly-Aromatic Hydrocarbons (PAH), toxic

metals and phtalates. And this is where Norit

Activated Carbon comes in!

Demonstration of Norit

Activated Carbon technology

For the removal of organic micropollutants –

such as pesticides, PAH, medicine residuals

and many others – Activated Carbon technol-

ogy is a key candidate. This has driven Norit

to participate in a high-profile development

and demonstration project which Rijnland

Water Authority (NL) has initiated, to com-

pare different technologies under practical

conditions. The project is co-financed by

STOWA (NL) and the EU Life program.

“We want to be prepared for the challenges

we’ll be facing as a result of the WFD based

treatment targets”, Wouter Dijksma, project

leader of Rijnland Water Authority. “It is

a fascinating project with excellent testing

facilities and a very valuable cooperation

between the project partners including Norit”,

sums Wilbert Menkveld of Witteveen+Bos

Consulting Engineers, overall coordinator of

the research program, up.

The European Union (EU) has made an ambitious start of the new millennium. Apart from

the expansion by 12 countries – including the latest, Rumania and Bulgaria – an ultra-important

The aim is to improve and protect the quality of Europe’s natural waters.

Safeguarding Europe’s natural waters

Norit and the EU 5th Water Framework Directive

Norit AirliftTM MBRThe current situation of water scarcity is leading to a continuous search for clean water.

Nonetheless, the United Nations have set their goals to work on providing the necessary

means to the 2.6 billion people around the world without access to clean sanitation today.

The result will be another increase in wastewater that needs treatment. Modern technologies

are challenged to meet the ever stricter requirements for a clean environment and better

usage of the available water sources.

Norit Airlift™ MBR is the ultimate technology

for the treatment of wastewater in a clean

and safe environment. It excels in several

beneficial ways:

Sidestream MBR

One of the major advantages of the Norit

MBR AirliftTM technology is that the mem-

branes are placed outside the bioreactor in a

clean and dry system set up. The wastewater

itself is inside the membranes rather than

outside, thus reducing the problem of

maintaining elements submerged in activated

sludge. Accordingly, the membranes are easi-

ly accessible and cleaned without having to

touch or smell the sludge. Moreover, because

the membrane filtration is completely separa-

ted from the bioreactor, the entire process is

running more efficiently.

Lower energy costs

Unlike traditional MBRs the Norit AirliftTM

MBR principle relies on air-bubbles, rather

than pumping to deliver the pressure across

the UF membrane. This gives an energy con-

sumption rate of less than 0.25 kWh/m³.

Highest permeate quality

The need for reusing wastewater, both indus-

trial and municipal, requires top quality

membranes which provide direct re-useable

water. The high quality Norit X-Flow mem-

branes applied in these applications filter

down to ultrafiltration level and can be

compared to the ones utilized in direct

potable water plants.

Low civil costs

Another advantage of the sidestream set-up

is that existing wastewater treatment plants

can be easily expanded. By adding the mem-

brane units to the existing plant, its capacity

can be advanced significantly, without increa-

sing footprint or civil works.

Focal point with regard to membrane techno-

logy has long been the improvement of

the availabe water quality. Purifying water

to meet drinking water requirements was

always the main objective. Recently, however,

the same membrane technology has been

applied for treating wastewater for re-use

or discharge. Norit’s energy efficient AirliftTM

MBR technology is the solution for municipal

applications, and, in special cases, for indus-

trial applications, where waste load ranges

are typical 300-600 mg/l COD.

Over the course of the last 10 years Ireland has seen much positive change

with the emergence of a fast growing economy. It has in turn become a very

important market for Norit. In February 2006, Norit Ireland was established

with the appointment of Ivan Rigney as Country Manager. The office is

responsible for the promotion and sales of Norit’s entire portfolio including

activated carbon, ultrafiltration membranes and solutions, valves, turnkey

process systems, CO2 recovery systems, blending, deaeration, and beer

membrane filtration systems.

investments? Ron Kesselmans, plant manager of the

Klazienaveen factory, answers this question: “The key

words are: increased production output and continuous

improvement on environmental and health & safety relat-

ed issues. Indeed, elaborating on a sustainable future of

our Activated Carbon production.”
