Wastewater treatment plays a vital role in maintaining environmental sustainability and public health. Central to effective wastewater treatment is the measurement and control of key parameters such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD). These parameters provide valuable insights into the organic and chemical composition of wastewater and help determine the appropriate treatment processes. The use of COD and BOD sensors in wastewater treatment is of utmost importance.
COD sensors are mainly used for monitoring rivers, lakes, sewage, and other types of surface water, etc., and can be easily integrated into water quality monitoring systems to meet customer needs.
COD Sensor Introduction
The optical method online COD sensor is more economical and environmentally friendly than the traditional chemical method. Small in size, easy to install, and can be used for continuous online water quality monitoring. Automatic compensation for turbidity disturbances, with automatic cleaning device, optional titanium alloy (corrosion resistant).
COD Sensor Feature
1, Digital sensor, RS-485 output, supports MODBUS.
2, Can measure COD, BOD, TSS, and temperature parameters.
3, No reagents, no pollution, more economical and environmentally friendly.
4, Small in size and easy to install, water quality monitoring can be performed online.
5, It automatically compensates for turbidity interference and has excellent test performance.
6, Internal rotation cleaning brush for pipe self-cleaning and submersible self-cleaning
