Small amounts of chemicals are used to form a “floc” that entraps particles.

Small amounts of chemicals are used to form a “floc” that entraps particles. Common flocculent chemicals include metal salts such as aluminum sulfate, ferric sulfate, and ferric chloride. Flocculation is often enhanced by adjustment of the pH with acid, lime, or carbon dioxide. Some plants use polymers in place of, or in addition to, metal salts.
