Raw Materials Clarification

Filtration of raw ingredients to remove particles and protect downstream processes. Particulate or crystal removal can be performed by depth filter media or membrane filters for many contaminants.

Chemical clarification consists of four phases: coagulation, flocculation, sedimentation, and filtration. Coagulation, essentially the addition of chemicals that are rapidly mixed with the water, usually involves the use of polymers and or the oxides of aluminum, iron, or calcium.
