What is a clarifier used for in water treatment?

A clarifier is an essential component in the water treatment process, specifically designed to remove suspended solids from water. It functions based on the principle of gravity, allowing heavier particles or solids to settle at the bottom of the tank over time. This settling process is critical in providing clearer water by separating the suspended material from the treated water.

While temperature control, chemical addition, and aeration are important processes in water treatment, they are not the primary functions of a clarifier. Temperature adjustments typically occur in different stages of treatment, chemicals are often added in various processes like coagulation or disinfection, and aeration generally takes place in other tanks designed specifically for introducing air into water to promote biological processes. The clarifier's role in facilitating the sedimentation of solids is crucial for producing high-quality water free from particulate contaminants.
