Oil Monitor For US Market

Modern Water has launched a range of oil in water monitoring products in the US and has supplied a Multisensor 1200 volatile organic compound (VOC) monitor to Glendive Water Treatment Plant in Montana to ensure safe drinking water for around 6,000 people.

Glendive Water Treatment plant’s decision to install the online VOC monitoring equipment came about as a result of an oil spill in January 2015 from the Poplar pipeline into the Yellowstone River. The Multisensor 1200 is currently providing continuous data for Glendive Water Treatment plant operators. Whenever VOCs, or other traces of oils are detected, an alarm will sound. If the benzene levels reach 2ppb, less than half of the maximum contamination level permitted by the US Environmental Protection Agency, the monitor triggers an alarm in the main control room and the plant operators will then shutdown the water treatment plant. Since the monitor was installed it has notified treatment plant staff of one incident where the level of VOCs were higher than normal. www.modernwater.com

Ammonium Analyser

Endress+Hauser has launched the Liquiline System CA80AM ammonium analyser for monitoring critical control points in water and resource reclamation facilities. The CA80AM analyser and its sample preparation systems are designed to provide an automated approach to process control and regulatory compliance.

The Liquiline CA80AM colorimetric analyser provides measurements by using the standard indophenol blue method, which is compliant to ISO 7150-1, DIN 38406-5 and GB 7481-87 standards. It also provides data storage and retrieval using on-board logbooks to allow continuous documentation for reporting to regulatory agencies.

Multiple communications methods, including EtherNet/IP, Modbus, Ethernet and an integrated web server, allow the analyser to be integrated into any control system. The integrated web server allows a user to remotely analyse process disturbances and decide on required measures quickly, all through any web browser. www.us.endress.com/ca80-analyzer

Automatic, Online Water Monitoring

Malvern Instruments has launched an online zeta potential analyser for water treatment allows water plant operators to control coagulation processes. The Zetasizer WT is a fully automated analyser that continuously monitors the properties of water during coagulation to provide precise and reliable data for optimizing chemical dosage levels. Delivering absolute (no calibration), highly sensitive analysis the new system enables a proactive response to changes in the process, enhancing plant stability and reducing the risk of significant events. The associated optimisation of charge neutralisation processes results in substantial financial benefits due to a reduction in chemicals usage.

The Zetasizer WT continuously measures zeta potential. Setting upper and lower zeta potential limits, beyond which floc formation is poor, provides the plant team with a defined target for safe operation and a simple and clear means of tuning coagulation. www.malvern.com/ZetasizerWT

Disinfectant Monitoring System For Chlorine Dioxide Measurement

GF Piping Systems has launched a reagent free Signet 4632 Chlorine Dioxide Analyser System. The new system features amperometric sensing technology, a clear flow cell, flow regulator, sensors, filter and variable area flow indicator all in one compact unit. The system is designed to provide a turnkey solution for accurately measuring residual Chlorine Dioxide levels up to 2 ppm/mg/l in a variety of water treatment applications. Key features of the new device consist of pre-wired electronics, a 120 VAC power plug, two 4 to 20 mA outputs and two dry contact mechanical relays. The plug and play analyser also provides a convenient visual indication of flow monitoring and allows for quick disconnect for the inlet port. In conjunction with the new analyser, GF Piping Systems is also introducing a convenient flow switch kit that is easily installed into the Chlorine Dioxide Analyser. The flow switch prevents chemical dosing when the flow is shut off by interrupting the transmitter’s mechanical relays. www.gfps.com
