South East Water Purchase HF microtol Turbidity for potable water process monitoring
Three white light microtol instruments have been supplied to the South East Water Company for installation on to various potable water processes. Two turbidimeters will replace the former HF Micro200BW instrument at one site after many years of service and the third instrument will compliment existing microtol installations. The HF turbidity technology has been used for over 15 years by the Water Company and favoured for it's simplicity of operation and calibration, in addition to the proven reliability the turbidity instrument has demonstrated.
Northumbrian Water has four more low flow turbidity installations commissioned
Pollution & Process Monitoring have commissioned four more turbidity monitoring stations within Northumbrian Water, suitable for continuous monitoring of final effluent at sites which have either intermittent or low flow conditions. The monitoring stations have been bespoke engineered by PPM. They comprise small GRP enclosures providing weather protection to the instrumentation and ancillary equipment. The turbidity sensors have been installed within a special flow cell with compressed air injection to automatically clean the sensor and sample supply pipe work.
To allow for continuous monitoring on these small rural sites, a special stainless steel trough has been designed and installed in the effluent channel, to retain a small amount of sample for analysis. The complete design has been evaluated over an extended period of time on a number of Northumbrian Water sites to ensure the common approach delivers a reliable measurement solution which can then be replicated across the catchment.
Protoc TOC analysers purchased for surface water monitoring at a major US International Airport
Vanguard Controls Inc. in the USA has secured a substantial project for a west coast international airport monitoring project. The package consists of four Web analyser and two Spyder controllers supplied with Paper Band Filtration providing sample conditioning. The water quality monitoring system is configured with one analyser ranged 0-50ppm, two at 0-500ppm and another supplied with automatic sample dilution, achieving a measuring range of 10,000ppm TOC.
