COAGULATION AND FLOCCULATION - MRWA
www.mrwa.comCoagulation 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 ...
Coagulation and Rapid Mixing - Oregon
www.oregon.govCoagulation by itself does not reduce turbidity. In fact, turbidity may increase during the coagulation process due to additional insoluble compounds that are generated by chemical addition. The processes of flocculation, sedimentation, and filtration should be used with coagulation to reduce suspended solids and turbidity. Coagulants and Polymers
