Analytical Technology Awarded Prestigious Framework Agreement by Thames Water

Dissolved oxygen (DO) is one of the most critical parameters in the activated sludge process and tighter consent targets now mean that utility companies including Thames Water need to review instrumentation to ensure that all wastewater treatment works are fully compliant. Analytical Technology’s optical dissolved oxygen monitor has been designed to provide reliable DO control while keeping maintenance to a minimum. The monitor is based on fluorescence quenching technology and provides continuous monitoring with virtually no servicing required.

Conventional oxygen sensors are often affected by process coating and any material that slows the diffusion of oxygen into the reaction cell will cause an error in the oxygen reading. Unlike traditional dissolved oxygen monitors, Analytical Technology’s Q45D-ODO contains an Auto-Clean function which generates a series of high pressure air blasts to remove contaminants from the face of the sensor and eliminate errors caused by fouling. The Q45D-ODO’s Auto-Clean capability will enable Thames Water to achieve continuous and reliable DO measurement without the risk of sensor fouling.

Garry Tabor, Sales Director at Analytical Technology, comments: “Dissolved oxygen monitoring is an essential process for water utility companies such as Thames Water. Analytical Technology supplies all Thames Water disinfection monitors, and its proven supply record over the years of the successful partnership means this new agreement reinforces our strong position as leading instrumentation providers within the UK water industry.”
