July 24, 2018 - Systematic disinfection is an essential step in water treatment and legally required in many areas to protect people and systems from illness or damage. However, high doses of disinfectants such as chlorine and chlorine dioxide can be toxic, which means compliance with limit values for those disinfectants is also very important. Endress+Hauser designed the Memosens CCS50D chlorine dioxide sensor to achieve a safe and efficient disinfection by providing stable measured values.
The chlorine dioxide sensor features a convex membrane made of dense, dirt-repellent material which prevents soiling and makes it resistant to biofouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, preventing dilution of the electrolyte.
Memosens CCS50D is able to deliver disinfection measurements at low flow rates. In combination with the Flowfit CCA151 assembly, for example, the required flow rate is as low as 1.3 gal/h (5 l/h), which means only a minimum amount of water is consumed in the bypass and the required disposal capacities are reduced.
Many skids in the food & beverage industry use chlorine dioxide for disinfection. These skids provide only small-volume samples for dosing control. Thanks to its special membrane design, Memosens CCS50D supports precise dosing of chlorine dioxide even in these skids.
The chlorine dioxide sensor is equipped with the proven Memosens technology by Endress+Hauser. Memosens allows for direct commissioning of new sensors without further calibration. During on-going operation, plant operators can pre-calibrate sensors in the lab, swap them into the process with plug & play, and continue measuring.
Chlorine dioxide is more and more becoming a disinfectant of choice because its handling has become easier. Today, chlorine dioxide is available as a ready-to-use solution that does not require manual mixing or the application of chemical generators. Memosens CCS50D is designed to support this trend. It helps plant managers comply with strict legal requirements on disinfection, whether it is in drinking water treatment, cooling systems, wash water for packed vegetables and salads, beverage production or desalination plants.
