Free & Total Chlorine in Wastewater Treatment
In municipal wastewater facilities, chlorination is a fundamental element of the treatment process, essential to disinfect the water and eliminate harmful pathogens. It can also benefit the activated sludge process and even mitigate greases, oils and odors across the treatment application. After chlorination is completed and disinfection confirmed, the wastewater then needs to be dechlorinated to almost undetectable levels to ensure the downstream environment is not exposed to harmful levels of chlorine or chlorine byproducts. Proper monitoring of chlorine is critical throughout the wastewater treatment process to ensure effective disinfection and a safe water supply. AlpHa’s amperometric RC67 and RC68 chlorine sensors provide a continuous, direct measurement of chlorine in parts per million (ppm).
