Monitoring Workshop on ‘Hydro-meteorological Instrumentation in India’

15th September 2014

Modern Water plc

• UK Group, founded 2006, ~ 50 staff worldwide

• Advanced innovative water treatment and monitoring

• Offices - Europe, USA, Middle East, South Africa,

Japan, China; Global Distributors – Sales in 50

countries!

Water and wastewater treatment

• Novel Forward Osmosis

• Electro-coagulation

Monitoring

• Fluorometers - BOD, Algal blooms, petroleum

hydrocarbons

• Trace (Heavy) Metals

• Toxicity - Microtox®

• Multisensor - VOC and THMs

• Environmental test kits for PCB, PAH, SRB, polymer etc

Fluorometry

• Fluorescence is the

emission of light by a

substance that has

absorbed light.

• Different molecules absorb

and emit light at specific

wavelengths.

• The concentration is a

function of the intensity of

the emitted light.

3 Bringing new technology to the water industry

HIGH SPECIFICITY AND HIGH SENSITIVITY!

BODChek

• New range of highly sensitive in situ UV fluorometers.

• Portable and online detection to Provide Real Time Monitoring of Organic Pollution.

• Detects fluorescent proteins (Tryptophan) that are inherent within sewage and slurry.

Key Applications

• Effluent contamination monitoring.

• General pollution event investigations.

• Water quality catchment surveys.

Why Tryptophan?

5 Bringing new technology to the water industry

• An essential amino acid in

human diet

• Main component of protein

fluorescence

• Associated with microbial

activity

• Sewage & faecal contamination

of waste waters, e.g. agricultural

runoff

Fluorescence correlates with BOD measurements!

AlgaeChek Ultra

• Algae deplete oxygen and certain species of

blue-green and red algae can even poison

aquatic life and pose a threat to human, domestic

animal or livestock health.

• Modern Water’s algae and algal toxin detection

technologies provide fast, accurate and

quantitative test results.

• 3 configurations available

• Chlorophyll-a, phycocyanin, turbidity (freshwater)

• Chlorophyll-a, phycoerytherin, phycocyanin (coastal)

• Chlorophyll-a, phycoerythrin, turbidity (seawater)

PetroChek

• Portable or on-line UV fluorimeter

• Identical to BODChek, but detects

at different wavelength

• Measures dissolved PAH (poly-

aromatic hydrocarbons) in water

• Applications:

• Oil refineries

• Fuel storage – leak monitoring

• Off-shore oil platforms

Trace (heavy) metals

• Examples:

• Copper, Lead, Cadmium, Zinc, Arsenic, Uranium

• From where?

• Industrial processes – car manufacturing,

battery recycling, metal plating, electronics etc….

• Mining – current mines, disused mines

• Naturally occurring – arsenic in bedrock in

SW UK (+ Italy, Turkey, China, Bangladesh, W

coast of America….)

• Drinking water contamination – accidental and

deliberate

• What’s the problem?

• Toxic to humans

• Toxic to environment 9

On Line Trace Metals Products

10

OVA7000 and OVA7000 Dual

Cell

• Unique on-line monitor

• Voltammetry-based

• Low detection limits (0.5 µg/l)

• Programmable for a variety of

metals and sample types

• 24/7 on-line monitoring with

process control

• Built in pre-treatment

OVA7000 DualCell OVA7000

Portable Trace Metals Monitoring

11

• PDV features and benefits:

• Low detection limits – able to detect to WHO

drinking water standards

• Portable – immediate results

• Analysis at remote locations with poor access

• Tracing contamination source and spread

• Use after natural disasters

=> Environmental protection

=> Human health protection

=> Flexible, dynamic sampling saves

man-hours compared to lab samples only

12

Toxicity Monitoring

• A toxicity test measures the effects of a chemical

on a living organism

• The severity of toxicity is proportional to the

exposure concentration and exposure time.

• Toxicity tests measure:

- Unknown compounds

- Effects of mixtures (synergistic effects)

• Examples of toxicity tests:

- Daphnia (plankton crustacean)

- Fathead Minnow (fish)

- Vibrio fischeri (bioluminescent bacteria)

13

Microtox® Reagent

Sick or dead bacteria with little or no light Healthy, bright, luminescent bacteria

Non-toxic Toxic

Gold Standard for Toxicity Monitoring! Validated data on >2700 chemicals.

25 years of Industrial and Research Experience.

Vibrio fischeri - bacteria indicator of human toxicity.

Microtox® M500 and Deltatox

• Microtox

• Bench-top system

• Toxicity – EC50, ISO protocol

• M500 Analyser

• Acute Toxicity Reagent

• Accessory reagents

• Deltatox

• Portable system

• Toxicity and ATP (bacterial contamination)

• Deltatox II Analyser

• Microtox SOLO reagent

• Accessory reagents

14

Microtox® CTM: On-line

15

• Acute ‘broadband’ toxicity.

• Microtox® CTM is a site-based, broad range,

Continuous Toxicity Monitor (CTM).

• It continuously measures the chemical toxicity

of a water source, giving instant indication of

water health.

• Fully automatic instrument that offers a 4-

week, autonomous operating cycle.

• Low level of skill for both operation and

maintenance.
