COAGULATION AND FLOCCULATION - MRWA www.mrwa.comGroundwater 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 appli ion of coagulation and flocculation depends upon these factors.

1.4: Coagulation and Flocculation - Workforce LibreTexts workforce.libretexts.org Flocculation Flocculation is the slow mixing process that causes smaller particles to merge into larger particles that settle more easily. The particles are then more easily removed in the sedimentation and filtration process. The process of flocculation is achieved by controlling the rate of impacts between particles as they gain size.

Lesson 4: Coagulation and Flocculation water.mecc.eduCoagulation/flocculation is a process used to remove turbidity, color, and some bacteria from water.
