Question: 1 / 400

What is the purpose of chlorination in wastewater treatment?

To stabilize pH levels

To disinfect the water by killing harmful pathogens

The purpose of chlorination in wastewater treatment is primarily to disinfect the water by killing harmful pathogens. Chlorine is a powerful disinfectant that effectively targets bacteria, viruses, and other microorganisms present in wastewater. This step is essential for ensuring the treated water is safe for discharge into the environment or for reuse, thus protecting public health and minimizing ecological impacts.

Chlorination also helps to reduce the levels of harmful substances in the effluent, making it suitable for its intended use. While pH stabilization, precipitation of heavy metals, and enhancing filtration efficiency are important processes in wastewater treatment, they do not directly relate to the primary role of chlorination, which centers on the disinfection aspect.
