The primary purpose of adding chlorine to water in a treatment facility is to disinfect the water. Chlorine effectively kills bacteria, viruses, and other microorganisms that can cause diseases, making it a crucial step in ensuring that the water is safe for human consumption.

While chlorine can have some ancillary effects on taste and may slightly influence pH levels, its primary function is disinfection. It acts as a strong oxidant, which disrupts the cellular processes of pathogens, rendering them inactive and thus preventing the spread of waterborne diseases.

Improving taste and removing sediments are not the main goals of chlorination. Taste improvements may be a side benefit depending on the specific water source and remaining compounds, while sediment removal typically involves physical processes such as sedimentation or filtration, rather than the application of chlorine.
