The first step in water treatment is coagulation, where chemicals are added to the water to help bind together small particles that are too small to be removed easily. The coagulants, such as aluminum sulfate, create larger particles called flocs, which can then be removed through sedimentation. During this process, the flocs settle at the bottom of the treatment tank, separating them from the water.
