COAGULATION AND FLOCCULATION
Coagulation and Flocculation Process Fundamentals 1 Coagulation and Flocculation Groundwater and surface water contain both dissolved and suspended particles Coagulation and flocculation are used to separate the suspended solids portion from the water Suspended particles vary in source, charge, particle size, shape, and density Correct

•The value of pH during coagulation optimal pH-range for Al: 6 - 7 8 Fe3+: 4 - 10 Fe2+: > 8 5 •Temperature •Mixing conditions In practice the coagulation process involves a rapid mixing, flocculation, sedimentation and filtration step Some of these steps are sometimes combined in water treatment practice
Coagulation, Flocculation and Clarification of Drinking Water
Coagulation Chemical treatment typically is applied prior to sedimentation and filtration to enhance the ability of a treatment process to remove particles Two steps typically are employed: coagulation and flocculation Coagulation is a process to neutralize charges and then to
