The removal of pathogens in wastewater treatment is fundamentally important for maintaining public health. Wastewater can contain a variety of harmful microorganisms, including bacteria, viruses, and parasites that can pose serious health risks to humans and animals if released untreated into the environment or if reused for purposes such as irrigation or industrial processes.

By effectively removing these pathogens, wastewater treatment processes help prevent the spread of waterborne diseases, which can result from contaminated water sources. Ensuring that treated water meets safety standards is crucial for protecting community health, preserving drinking water quality, and safeguarding ecosystems. While enhancing aesthetic quality, improving treatment facility performance, and increasing efficiency in processes like denitrification are important considerations in wastewater treatment, the primary driving force behind pathogen removal is the imperative to protect public health.
