About this document
Types and Uses of Coagulants by Burhan is a document available to read on EtoBox.
Primary coagulants such as alum neutralize the electrical charges of particles in water to cause them to clump together to form flocs, while coagulant aids add density and strength to slow-settling flocs. Common primary coagulants are alum, ferric sulfate, and ferric chloride, whereas common coagulant aids include polymers, lime, bentonite, and calcium carbonate. Different water sources require different coagulant chemicals, but alum and ferric sulfate are most frequently used.
