OxyTechw² OPT Dissolved Oxygen Sensor

The OxyTechw² OPT Sensor has been designed to provide highly reliable Dissolved Oxygen measurements using the industry accepted optical luminescent technology. Optical measurement of dissolved oxygen offers some improvement over older galvanic type sensors, this includes extended times between maintenance, no drift, a faster response and allows installation in applications where there is low or no flow.

For installation in activated sludge plants (ASP's) we recommend that the sensor is installed using our specially designed self cleaning mounting system, with a flexible joint in the mounting shaft. The flexible joint moves the sensor in the process, keeping the membrane clean by reducing bio-fouling without the use of a compressor and with the added benefit of allowing rags to fall away from the assembly. This motion is similar to that achieved by using a floating ball assembly, with the added advantage of placing the sensor below the surface of the liquor. This means that the sensor is below the level of the floating fats and greases that accumulate at the surface and results in the Dissolved Oxygen reading being more representative of the whole tank.

The OxyTechw² OPT provides the reliable, accurate measurement that is required to operate activated sludge plants at the optimum Dissolved Oxygen concentration, maintaining the balance between the running costs of blowers and aerators and the need to produce high quality effluent.
