Measuring real-time COD is becoming increasingly important as we strive to take better care of the environment. In-line COD measurement will help you to trace leaks in the factory and to determine their possible causes. This can save money during the production process as well as in the WWTP (less consumption of oxygen and therefore less sludge).
COD is normally measured in the laboratory through chemical reactions with oxygen. Rhosonics offers a different way to measure the amount of COD in real time: CODeq (equivalant results, but using improved technology). Rhosonics uses a combination of multiple ultrasonic technologies in a single sensor, in combination with a conductivity sensor, to determine CODeq and TSSeq: the model 9585. The factory-programmed calibration is an advanced regression model, based on the ultrasonic properties of a variety of the most common organic materials, such as alcohols, sugars, and so on.
The Rhosonics Model 9585 employs a hybrid ultrasonic sensor that measures a number of ultrasonic properties of water. In conjunction with the electrical conductivity, an ultrasonic equivalent value can be reached to determine the COD value of the water
