Coagulants, such as alum (aluminum sulfate) and ferric chloride, are also employed in sewage treatment. These chemicals assist in the removal of suspended solids, colloidal particles, and turbidity from wastewater. When added to the treatment process, coagulants promote the aggregation of small particles into larger flocs, which can be more easily removed through sedimentation. This process is particularly important in primary treatment phases, where physical separation of solids occurs.
