Thames Water announced that it has awarded a three-year framework contract to Analytical Technology, a developer of electrochemical sensors, to deploy optical dissolved oxygen monitors across numerous Thames Water wastewater treatment plants. The installation of the optical dissolved oxygen monitors are aimed at enhancing the process control.
Q45D-ODO monitor
Thames Water chose Analytical Technology’s Q45D-ODO monitor from a group of nine instrumentation bidders. Analytical Technology exhibited improved customer support for the disinfection monitors that were already deployed in the Thames Water. The company also highlighted whole-life savings and cost savings. Whole-life savings will be attained through decreased cost of spares and through lesser maintenance.
Dissolved oxygen (DO) is a vital parameter in the sludge process. Tighter consent targets mean that firms that include Thames Water have to review the instrumentation to assure all the wastewater treatment functions are completely compliant. The optical dissolved oxygen monitor of Analytical Technology offers DO control and keeps maintenance costs to a minimum. The Q45D-ODO monitor is based on the fluorescence quenching technology. It offers continuous monitoring with very less servicing.
Traditional oxygen sensors are frequently affected by process coating. Any material that hampers oxygen diffusion into the reaction cell is likely to cause a fault in the oxygen reading. The Q45D-ODO features an Auto-Clean function that produces high-pressure air blasts to eliminate contaminants and to eradicate the errors that are caused by fouling. The Auto-Clean capability will allow Thames Water to attain reliable and continuous DO measurement.
