Designed, manufactured and assembled by Hyflux in Singapore, the Standard Membrane Systems integrate modular, scalable Kristal® hollow fibre UF and reverse osmosis (RO) membrane units and components to deliver exceptional performance and value.

Kristal® UF membranes have a cross-flow and out-to-in configuration which make them ideal for pre-treatment for RO systems. The membranes produce consistent, high quality product water even in turbid feed water of variable quality such as seawater or various types of river water. This protects the RO membranes, optimises the system’s operation and ensures a longer lifespan for the RO membranes. With lower energy use and maintenance costs, industries and communities can enjoy savings over the long-term.

In addition, industries and communities can be assured of the quality of the membranes in delivering clean, safe drinking water. Kristal® is the first UF membrane certified to remove the drinking water contaminants, cryptosporidium and giardia, under the NSF Public Drinking Water Equipment Performance Certification Programme. It has also achieved NSF/ANSI Standard 61 (Drinking Water System Components – Health Effects) Certification.

SEAWATER DESALINATION FOR BOILER FEED WATER

CASE STUDIES

BackgroundZhejiang ranks as one of the top provinces in China in terms of economic progress and general prosperity. Much of the energy required to feed its booming industries comes from coal-fired thermal power plants that rely on seawater desalination technology to provide clean water for their boilers.

One such power plant, located in the town of Wushashan requires a treated boiler feed water capacity of up to 22,200 m3/day. A desalination plant is being designed to meet this requirement by desalting water from the East China Sea. As boiler feed water has to have a high level of purity, various salts, silica and suspended particles in the seawater need to be removed.

SolutionA two-pass RO system was designed and installed by Hyflux for this application. 1,820 SWRO elements were used in the first pass and 324 BWRO elements in the second pass. This ensures that the permeate quality meets the strict demands for boiler feed water.

SEAWATER DESALINATION FOR INDUSTRIAL PROCESS APPLICATION

CASE STUDIES

SolutionHyflux was selected to design, install and commission the plant, which would include a two-pass RO system preceded by Hyflux’s proprietary Kristal® UF membrane system to ensure a constant supply of consistent, high quality feed water.

A total of 400 Kristal® membranes, 784 SWRO elements and 252 BWRO elements were designed for the system. The product water from the desalination plant will go through a demineralisation system before being used to generate steam for the manufacturing process.

BackgroundA fertiliser factory located in the city of Bontang in East Kalimantan requires up to 7,200 m3/day of clean water to manufacture ammonia and urea. The factory needs a system capable of performing with long mean time between failures (MTBF) and supplying water of a high quality to generate steam for the manufacturing process. Given its close proximity to the sea, seawater desalination is a feasible option for a sustainable source of water.

CASE STUDIES

BackgroundA crude palm oil refinery situated in a rural part of Sumatra had been depending on deep well water or trucked surface water from other provinces to supply clean water to its refinery boilers. At times, it was a challenge to maintain a steady supply from these sources.

The refinery needed a reliable supply of clean water to ensure operations would not be disrupted. As the facility was located near the coast, it hoped to tap on seawater desalination for a sustainable source of water to meet its needs. However, the turbidity of the seawater could fluctuate widely between 30 to 151 NTU because the sea was near a zone of peat swamps and had been badly polluted by poorly treated discharge from surrounding factories.

SEAWATER DESALINATION FOR PALM OIL REFINERY

CASE STUDIES

238 SWRO elements were used for the first pass while 72 BWRO elements were used for the second pass. 144 Kristal® UF membranes were installed to provide constant, high quality feed water for the RO membranes.

Hyflux’s solution provides high quality boiler feed water for the refinery as well as a cost-effective, reliable water supply that does not leave it vulnerable to supply disruptions.

SURFACE WATER TREATMENT FOR BOILER FEED WATER

CASE STUDIES

BackgroundBoilers are used in thermal power plants to produce steam that drives the generation of electricity. To produce the steam, these boilers require water of a very high quality. Scaling and corrosion tend to be common issues faced by boilers, so the boiler feed water must not contain any minerals or non-volatile salts.

One such thermal power plant, located in the town of Zhou Cheng in Shandong province, requires up to 200 m3/hour of treated water for its boilers. The source of the raw water is a reservoir nearby. As the quality of the reservoir water tends to fluctuate depending on various factors such as seasonal and weather changes, a robust water treatment system is needed.

SURFACE WATER TREATMENT FOR BOILER FEED WATER

CASE STUDIES

SolutionHyflux was tasked to design, fabricate, install, commission, as well as operate and maintain the water treatment system for the boiler feed. 216 RO elements and 60 of Hyflux’s Kristal® UF modules were used as the key technologies for the system.

The UF-RO system produces high quality product water that is further polished with an ion exchange mixed bed before being used as boiler feed.

RIVER WATER TREATMENT FOR TEXTILE PROCESS WATER

CASE STUDIES

BackgroundClean water is an extremely important “raw material” for the textile industry because large quantities are constantly needed in the manufacturing processes. The water quality requirements of some of these processes are stringent. In particular, water used for textile wet processing such as dyeing requires water that is relatively free from colour, hardness and solids – both suspended and dissolved.

An apparel factory in Malaysia that relied on a nearby river as a source of water for its manufacturing processes, had its intake point located downstream from other factories which discharged their treated wastewater into the river. As a result, the river water contained high levels of both organic and inorganic compounds that needed to be removed before it could be used in the factory’s dyeing process as well as other applications such as steam generation.

RIVER WATER TREATMENT FOR TEXTILE PROCESS WATER

CASE STUDIES

SolutionGiven the stringent water quality requirements, Hyflux designed, engineered, supplied, installed and commissioned a dual membrane filtration system with low pressure reverse osmosis (LPRO) as the key treatment technology. In addition, Hyflux’s proprietary Kristal® UF membrane was chosen as the ideal pre-treatment to the LPRO. In total, 432 Kristal® modules and 648 RO elements were used.

Since 2006, the system has been producing up to 14,400 m3/day of consistently high quality water for the textile manufacturing applications, especially dyeing.

THE KRISTAL® ADVANTAGE


23


Membrane material, surface properties and make-up are crucial to any membrane’s performance. Hyflux’s Kristal® membranes are made from carefully selected materials which are further enhanced by the modification of its surface properties to achieve high levels of hydrophilicity. The result is high flux rates, low fouling tendencies and enhanced chemical resistance.

To cater to harsher operating conditions, Hyflux has developed a unique tri-bore membrane. This design not only delivers greater durability and strength that enable the membrane fibres to maintain their integrity, but also the same high level of permeate production as the single bore membrane.

THE KRISTAL® ADVANTAGE: HYDROPHILISED, ENHANCED POLYMERIC MATERIAL

THE KRISTAL® ADVANTAGE: CONSISTENT, HIGH QUALITY PERMEATE

One of the key strengths of the Kristal® membrane is its proven ability to produce high quality permeate regardless of fluctuations in feed water.

The following graphs illustrate the permeate turbidity and silt density index (SDI) levels of a desalination plant using Kristal® for RO pre-treatment over a year’s operation.
