Another essential chemical in sewage treatment is alum, or aluminum sulfate. Alum is a coagulant used in the primary treatment phase to facilitate the removal of suspended solids and colloidal particles. By causing these particles to clump together, or coagulate, alum aids in their subsequent removal through sedimentation. This is particularly important in reducing the turbidity of wastewater, thus improving the efficiency of subsequent treatment processes. The addition of alum not only enhances removal rates but also aids in the stabilization of organic matter.
