What does a hypochlorinator do?

A hypochlorinator is specifically designed to inject a liquid chlorine solution into a water supply as part of the water treatment process. The primary purpose of adding chlorine is to disinfect the water, eliminating harmful microorganisms and pathogens that can lead to waterborne diseases. This process is crucial in ensuring that the water is safe for public consumption.

In the context of the other options, removing minerals from water pertains to processes like softening or filtration, which are not functions of a hypochlorinator. Increasing water pressure typically involves pumps or pressurization systems, while cooling water may be necessary in certain industrial applications or processes, but is unrelated to the function of a hypochlorinator. Thus, the hypochlorinator's role is focused solely on enhancing water quality through disinfection via chlorine addition.
