Water/Wastewater 37 Continuous Toxicity Monitoring Cymtox Ltd is a wholly owned subsidiary of Modern Water plc. It develops and markets leading-edge water and wastewater monitoring solutions.
Online Real-Time Detection of Toxic Agents in Water and Wastewater Monitoring of water toxicity using biosensors has become a widely accepted technique. Bacterial biosensors offer simple and reproducible tests that can be automated, with reagents that can be stored. The new CTM™ Continuous Toxicity Monitor makes fully automatic, continuous, on-line testing a reality.
Certain strains of bacteria emit light when healthy. When they are exposed to toxic substances, the amount of light emitted reduces. The greater the toxicity of the sample, the lower the light emitted. This has been shown over many years to be a reproducible effect. Measuring changes in light between healthy bacteria and bacteria exposed to toxic substances will therefore indicate presence in a water sample.
The CTM™ Continuous Toxicity Monitor automatically and simultaneously detects a broad range of toxicants including metals, pesticides, fungicides, herbicides, chlorinated solvents, industrial chemicals and algal toxins. The presence of harmful contaminants in waters and wastewaters is detected without having to monitor for a wide range of specific chemicals.

OTT Hydrometry, the hydrometeoro- logical and water quality instrumentation company, has moved from a location near Nottingham to a new larger facility in Barlborough, just south of Sheffield.
Explaining the relocation, Managing
Director, Simon Wills said: "Our business has grown substantially, year on year, both from increased sales of instrumentation and from a greater volume of environmental monitoring services. The new facility will accommodate the current business and provide further room for expansion."
The company’s growth has been driven by technological developments that have enabled the widespread adoption of integrated environmental monitoring systems, often providing data via the internet using the recently launched OTT NetView web based data monitoring product. At the same time, the European Water Framework Directive has created a growing need for catchment monitoring strategies that require hydrometeorological instrumentation and systems.

InfraCal TOG/TPH Analyzers let you quickly and easily:
• analyze produced water on offshore oil platforms
Water and Wastewater Quality Measurement Specialists
Pollution & Process Monitoring is an established UK manufacturer and distributor of on-line instrumentation for water and waste quality measurement. The company specialises in the manufacture and integration of instrumentation into engineered systems including analyser kiosks. PPM also represents a number of leading international manufacturers including WTW, Germany - manufacturing closely associated products. The technology from PPM includes MCERTS approved Protoc
TOC and ProAm ammonia (ISE) analysers both manufactured by PPM and new digital technology allowing the integration of multiple sensors including DO by fluorescence, Ammonium, Turbidity and MLSS in-situ measurement manufactured by WTW.
• monitor refinery or industrial plant wastewater effluents
• measure FOG discharge levels into treatment centers
With over 2,000 in operation, InfraCal Analyzers are the worldwide industry standard for on-site measurement of total oil and grease (TOG), total petroleum hydrocarbons (TPH) or Fats, Oils and Grease (FOG) in water.
Don’t wait for off-site lab tests to ensure compliance as fines for discharges above permit requirements can be costly – often more than the price of an InfraCal TOG/TPH Analyzer!

“There has been a significant increase in the number of water authorities and environmental consultants who have chosen Chelsea’s (UK) dye tracing systems” reports Bruce Kimber, Chelsea’s Customer Services Manager.
“This is mainly due to the system’s reliability, ease of use and low cost. The system is also highly sensitive, robust, and delivers real-time data. It includes a GUI which allows GPS tagged data to be sent via a Bluetooth wireless link to either a PDA or a PC for viewing and storage, thus giving the user freedom in the field to make high precision measurements anywhere, anytime. It can be moored, profiled, towed or affixed to ROV / AUV platforms.”
Typical applications for the dye tracing system include environmental monitoring, pollution control, process control within water treatment plants, commissioning of sewage treatment works and monitoring of pipeline integrity. “The benefit of this system over others” reports Bruce Kimber, “is that it is highly reliable and can be configured to measure a wide range of dyes including rhodamine, fluorescein & other specialist UV tracer dyes.”
