Optical Dissolved Oxygen Sensor for Sewage Treatment

Specifications and Technical Details

The following are some of the key specifications and technical details of optical dissolved oxygen sensors:

• Signal Output: RS485 Modbus, supporting standard communication protocols for easy integration into existing systems.
• Measurement Range: Typically 0-20 mg/L with high accuracy and precision.
• Response Time: Fast response times, with T90 values of less than 25 seconds for 0->100% and less than 30 seconds for 100->0%.
• Temperature Compensation: Automatic temperature compensation ensures accurate measurements over a wide range of temperatures.
• Material and Construction: PPS housing material and 316 SS head for corrosion resistance and durability.

Applications in Sewage Treatment

Optical dissolved oxygen sensors are widely used in sewage treatment applications to monitor and control dissolved oxygen levels. By ensuring that dissolved oxygen levels are maintained within the optimal range (typically 1-3 mg/L), these sensors help to optimize the performance of activated sludge processes and reduce power consumption. They are also useful for detecting and preventing problems such as sludge bulking and scum formation.
