Water clarification

Water clarification is the process for making water suitable for a specific application or for discharge into public waters.  Untreated water can contain a variety of contaminants that require removal prior to end use, including clays, heavy metals, color bodies, organics, pathogenic bacteria, giardia cysts, and viruses.

Clarification for the production of drinking water utilizes the combined action of chemical coagulation, flocculation, sedimentation, filtration, and disinfection.  Inorganic coagulants are proven to be effective in water clarification.  Alkalinity and pH both must also be maintained in the proper range.  Sometimes an alkali, such as CAL~FLO® slurry, will be required for effective coagulation.
