The purpose of chlorination in sewage treatment primarily focuses on disinfection. This process involves adding chlorine to wastewater to kill harmful bacteria and pathogens, thereby reducing the risk of disease transmission when treated water is released into the environment or reused. Chlorination is critical in ensuring that the effluent meets public health standards before being discharged into water bodies or used for irrigation.

While enhancing the biological treatment process or recovering nutrients for agriculture are vital aspects of overall sewage treatment, they are not the direct aims of chlorination. Similarly, improving the physical setting of the treatment plant relates more to infrastructure and operational management rather than the specific function of chlorination. Thus, disinfection through chlorination stands out as the key purpose, ensuring that the treated wastewater is safe for its intended final use.
