What is the role of chlorine in wastewater treatment?

Chlorine plays a pivotal role in wastewater treatment primarily as a disinfecting agent. When added to wastewater, chlorine is effective in inactivating a wide range of pathogenic microorganisms, including bacteria, viruses, and protozoa. This disinfection process is crucial in ensuring that the effluent released into the environment meets health and safety standards, significantly reducing the potential for waterborne diseases and protecting public health.

The use of chlorine helps achieve a clean and safe discharge before the treated water is released, making it an essential step in the treatment process. While chlorine may interact with various components of wastewater during treatment, its primary function remains focused on the disinfection of pathogens, showcasing its importance in protecting both human and environmental health.
