The primary objective of sewage treatment plants for hospitals is to treat the wastewater influent, thereby mitigating the risk of transmitting dangerous diseases to humans. Wastewater from hospitals is directed to the treatment plant, where it undergoes several stages of treatment facilitated by drains and collectors. Effective sewage treatment plants tailored for hospitals are typically compact, incorporating mechanical, chemical, and biological treatments and techniques aimed at minimizing environmental pollution, particularly water pollution.
Hospital sewage contains a variety of contaminants, including pathogens, pharmaceuticals, chemicals, and hazardous substances. Proper treatment is essential to prevent environmental contamination and protect human health, especially in a city like Chennai.
Hospital wastewater is laden with microbial pathogens, pharmaceuticals, radioactive isotopes, hazardous chemicals, heavy metals, and drug residues, making it crucial to implement effective treatment measures to ensure public health and environmental safety in Chennai.
The treatment process involves preliminary pretreatment to remove large debris, primary treatment for physical separation of solids and greases, secondary biological treatment to degrade organic matter, and tertiary treatment for disinfection and removal of remaining contaminants, ensuring that the treated water is safe for discharge or reuse.
Sewage treatment plants in hospitals are crucial to reduce harmful environmental impacts. Effective treatment ensures safe disposal or reuse of water, protecting both human health and the natural environment from hazardous contaminants, contributing to a healthier and cleaner environment in Chennai.
