What type of pollutants are targeted for removal by a disinfection system in wastewater treatment?

The disinfection system in wastewater treatment primarily targets pathogens, which include bacteria, viruses, protozoa, and other microorganisms that can pose a risk to public health and the environment. The goal of disinfection is to kill or inactivate these harmful organisms to ensure that treated water is safe for discharge into receiving waters or for reuse.

Disinfection processes, such as chlorination, ultraviolet (UV) radiation, and ozonation, are specifically designed to disrupt the life cycles of pathogens, thereby reducing the risk of disease transmission. While other pollutants such as organic compounds, suspended solids, and nutrients can also be removed or reduced during wastewater treatment, they are generally addressed in different stages of the treatment process rather than through disinfection specifically.

By focusing on pathogens, disinfection systems play a critical role in protecting public health and maintaining environmental quality in the wastewater treatment process.
