1 On-line and portable water monitoring equipment Anna Whittaker, European Sales Manager Majis Inward Mission British Water 12 April 2016 Bringing new technology to the water industry

2 Modern Water Monitoring Toxicity on-line and portable/lab Trace Metals on-line and portable Fluorometers Algae / BOD / Petro-oil Test kits ATP, pesticides etc. Multisensor on-line VOC and THM 2

3 Modern Water plc UK Group, founded 2006, ~ 60 staff worldwide Advanced innovative water treatment and monitoring Europe, USA, Middle East, South Africa, Japan, China Water and wastewater treatment Novel Forward Osmosis Electro-coagulation Seawater Cycle Process Monitoring Toxicity, Heavy Metals VOC, THM Algal blooms, petroleum hydrocarbons Immunoassay tests kits for PCB, PAH, SRB, polymer etc Bringing new technology to the water industry 3

4 Microtox M500 Bench-top toxicity TOXICITY Microtox CTM Continuous Toxicity Monitor 4

5 What is Toxicity 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) 5

6 Bacterial Bioluminescence -Vibrio fischeri Vibrio fischeri - bacteria sourced from pacific ocean squid Bacteria emit light when healthy Light output reduces rapidly on contact with toxins 'Inhibition Indicator of human toxicity Microtox Reagent = freeze-dried V. fischeri Bacterium Culture Symbiosis with squid

7 Microtox Reagent Non-toxic Toxic Healthy, bright, luminescent bacteria Sick or dead bacteria with little or no light 7

8 Microtox CTM Acute broadband toxicity Instant indication of water health detects unknown contaminants Validated data on >2700 chemicals As good as, or lower levels of detection than other biosensor systems Microtox is widely accepted in water industry as indicator of human toxicity Works in chlorinated water and high Total Suspended Solids (TSS) Bringing new technology to the water industry 8

9 Microtox CTM Treatment and Cleaning Reagents Nutrient Bag Drawer Water inlet Catchpot Autosampler Temperature controlled section houses growth and detection system Fermentor Waste Bringing new technology to the water industry 9

10 Bioreagent growth and detection Bioreagent/ sample mixing point Photomultiplier tube Nutrient supply Bioreagent pump Air supply Sterile waste Bringing new technology to the water industry Fermentor Vibrio fischeri bacteria 10

11 Markets for CTM Drinking water intake Industrial discharges/ recycling High security Buildings/ distribution Oil well discharges Potential Terrorist targets Fresh, saline, chlorinated and waste waters 11

12 Municipal WWTP CTM CTM Bringing new technology to the water industry 12

13 Drinking water intake protection CTM CTM monitors at intake to plant Alarms Automatic stop of intake => Drinking water protection for thousands of people 13

14 Toxicity 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

15 Microtox Users (Partial list) Bringing new technology to the water industry 15

16 Toxicity Microtox at Olympics Microtox used at every Summer Olympics since 1984 Provides additional confirmation water is safe during the event In London Thames Water used Microtox at their lab and tested samples every day In Beijing Microtox was used every 15 min at critical places Protects athletes and public from deliberate or accidental contamination 16

17 TRACE METALS MONITORING Bringing new technology to the water industry 17

18 What are trace metals? Why monitor? 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 18

19 Trace Metals Products On Line Monitor OVA7000 and OVA7000 Dual 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 Portable Analyser PDV6000 ultra Portable heavy metal analyser for field and laboratory Fast results down to low ppb levels Suitable for water and soil OVA7000 OVA7000 DualCell 19

20 Metals Treatment Plant Cost savings and environmental protection Untreated influent Discharge of treated effluent Metals treatment system Lab sample Lab sample 20

21 Metals Treatment Plant Cost savings and environmental protection 1. Metal levels vary Have to add treatment chemicals (flocculants) to cover spike levels 2. Laboratory samples Untreated influent During treatment process Treated effluent Frequency: Daily/weekly/monthly Time to result: 1 2 weeks Pb ppm OVA & ICP Stream 2 Pb Pb2 Pb ICP 16-Jan 17-Jan 18-Jan 19-Jan 20-Jan 21-Jan 22-Jan 23-Jan 24-Jan 25-Jan 26-Jan Problems => Overdosing! => Spike missed => Risk of environmental fines => Difficult to manage process 21 Bringing new technology to the water industry

22 Metals Treatment Plant Cost savings and environmental protection Metals treatment system Discharge of treated effluent Alarms Automatic diversions of flow Automatic dosing adjustments OVA 22

23 Metals Treatment Plant Cost savings and environmental protection On-line monitoring benefits 6 5 Stream 2 Pb Large savings on treatment chemicals (6x reduction) Effects of changes in process immediately visible Minimise risk of effluent breaching consent limit No environmental fines Protection of brand Pb ppm OVA & ICP Pb2 Pb ICP Amount of treatment chemical Jan 17-Jan 18-Jan 19-Jan 20-Jan 21-Jan 22-Jan 23-Jan 24-Jan 25-Jan 26-Jan Levels measured by OVA automatically dose treatment chemicals Bringing new technology to the water industry 23

24 Metal Treatment Plant - Example Automotive & aerospace engine manufacturer, UK Casting foundry Ni and Cr in waste water from alloys used OVA installed in the WWTP just before the discharge Monitors Ni and Cr (0.5 ppm Cr, 1 ppm Ni) Analogue output to WWTP process control PC Benefits: - Effluent monitored continuously not exceed limits - WWTP control; high levels trigger change in process 24

25 Jeddah Project Supply of monitoring station. Client Hyundai Heavy Industries Scope Design, supply, commissioning and end client training Equipment installed - OVA7000 Dualcell x 2 Monitoring for As, Hg, Co, Ni, Cr, Ag, Cd, Pb, Cu, Zn, Mn, Fe SPX Powermon Analyser x 1 Monitoring for Al Chloride analysers x 2 25

26 ENVIRONMENTAL TEST KITS 26

27 Environmental test kits For laboratory and field use Contaminated land soil and water Pesticides soil and water Algal toxins water only ATP test for bacterial contamination Drinking water, oil/gas industry, heating/cooling industry, paper SRB test for specific type of bacteria (Sulphate Reducing Bacteria) Cause corrosion in oil/gas pipes 27
