The NIWA investigates whether we need to monitor nitrate concentration continuously and looks at progress in practical nitrate monitoring.
The rugged ST100 Series Thermal Flow Meter from Fluid Components International (FCI) provides precision mass flow measurement, making it useful for engineers and operators responsible for measuring gas production from digester tanks at municipal or industrial wastewater treatment operations.
DCM Process Control's toxic shock risk study is a comprehensive analysis of influent composition and concentration. The tool provides operators and plant management with a clear picture of the activity and discharge patterns of industries and, more importantly, the process response of the receiving WWTP.
Activated sludge systems combined with the use of engineered and natural plants creates an aesthetically pleasing wastewater treatment plant.
A new radar sensor from Vega has been optimised for the widely different applications in the water/wastewater industry.
The BeanAir wireless sensor network (WSN) enables real-time monitoring of performance and environment. An integrated system allows BeanGateway/BeanDevice to operate without an internal battery.
Emerson Process Management is replacing an outdated SCADA system and remote terminal units (RTUs) used throughout Hampton Roads Sanitation District's (HRSD) vast wastewater collection system.
Emerson has enhanced the software for its Fisher FIELDVUE DVC6200 series digital valve controllers, which are now available for use by process industries with PLCs and PROFIBUS communications as the dominant protocol.
The portable Cerlic MultiTracker has helped busy plant operators greatly reduce their daily lab work by providing fast and repeatable measurements for MLSS/RAS/WAS/sludge blanket profile and dissolved oxygen, without having to step into the lab.
Rimini, Italy, boasts the biggest wastewater treatment plant (WWTP) using membrane bioreactor (MBR) technology in Europe. Its cost-effective MBR upgrade and advanced performance has allowed the centralisation of Italian coast wastewater, the demolition of redundant surrounding WWTPs and an improved unpolluted tourist coastline.
A wastewater treatment plant in the US has used a dynamic imaging particle analysis system to monitor the condition and presence of methanogens in its anaerobic digestion process to find a potential correlation with methane production.
The FlowCAM imaging particle analysis system is a tool for detecting, identifying and quantifying algae or problem particulate matter in water treatment processes.
Furphy Engineering has introduced the Robotic Tank Inspection Technology, which is claimed to increase safety, reduce risk and improve the accuracy of tank inspections.
Areas of wastewater treatment plants that are subject to flooding, such as wet wells and influent headworks, are suitable for MSA's Tri-Gas sample draw custom system. The system can monitor oxygen, hydrogen sulfide and combustible gases (methane or petroleum vapours).
The TriGard Gas Monitor detects chlorine, sulfur dioxide, other toxic gases, remote combustible gases and oxygen deficiency or enrichment. The monitors are designed specifically for water and wastewater applications.
