What is the role of a chlorination tank in water treatment?

The chlorination tank is crucial in the water treatment process, specifically serving the function of mixing chlorine with water for disinfection. Chlorine is a powerful disinfectant that is used to eliminate harmful microorganisms and pathogens in the water supply, ensuring that the water is safe for human consumption.

In the chlorination tank, the chlorine is dissolved in water and thoroughly mixed to provide a uniform concentration throughout the water. This process maximizes the effectiveness of the disinfection process because it allows the chlorine to come into contact with a larger number of microorganisms, thus enhancing the overall quality and safety of the water.

The other options describe functions that a chlorination tank does not perform. While the tank could be involved in the overall water treatment system, its primary purpose remains focused on disinfection through chlorine mixing, making it integral to the treatment regimen used to provide clean and safe drinking water.
