Bourke, N., Carty, G., O’Leary, G., Crowe, M., Page, D (2002) Water Treatment Manuals Coagulation, Flocculation & Clarification
Absolutely pure water is rarely, if ever, found in nature. The impurities occur in three progressively finer states - suspended, colloidal and dissolved matter. Different methods of treatment are required for their removal or reduction to acceptable limits. Coagulation, Flocculation and Clarification, as well as Filtration are interdependent stages of the solids separationphase of water treatment. Failure or inadequacy in any of the stages will have adverse […]
