Electrochemical sensor manufacturer Analytical Technology (UK) announces that it has been awarded a framework agreement to supply dissolved ammonia monitoring systems to Wessex Water.
Following a detailed decision-making process in which Wessex Water evaluated a range of monitors against stringent criteria, Analytical Technology was awarded an AMP 5 framework agreement for its Q45N dissolved ammonia monitor.
Wessex Water is a regional water and sewage treatment business serving an area of the south west of England, covering 10,000 square kilometres including Dorset, Somerset, Bristol, most of Wiltshire and parts of Gloucestershire and Hampshire. The new agreement reaffirms Analytical Technology’s position as a leading supplier of water monitoring instrumentation to the majority of the UK’s largest utility companies, including Thames Water, Yorkshire Water, South West Water, United Utilities, Anglian Water and Severn Trent.
Analytical Technology’s Q45N dissolved ammonia monitor provides a new approach to on-line ammonia monitoring. The system uses reaction chemistry that converts ammonia in solution to a stable monochloramine compound that is equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines, while eliminating interference from excess free chlorine in solution. The Q45N system provides the measurement stability needed to avoid complicated automatic calibration systems and provides excellent repeatability over long periods.
