Simulation of coagulation, flocculation, and sedimentation
The computer program ZB2 was used to study simulated coagulation, flocculation, and sedimentation. The effect of the initial velocity of soil particles on the values of reaction-rate constants was investigated. In this respect, the results obtained with the program ZB2 corresponded to the theory and realities of coagulation carried out under

water supply system Coagulation and flocculation
Coagulation and flocculation Suspended particles cannot be removed completely by plain settling. Large, heavy particles settle out readily, but smaller and lighter particles settle very slowly or in some cases do not settle at all. Because of this, the sedimentation step is usually preceded by a chemical process known as coagulation.

Flocculation follows the coagulation step. Flocculation is the gentle mixing of the water to form larger, heavier particles called flocs. Often, water treatment plants will add additional chemicals during this step to help the flocs form.

Coagulation Flocculation Drinking Water
Many water purification methods require pretreatments such as coagulation and flocculation. A coagulant is added to the source water in traditional coagulation-flocculation-sedimentation to produce an attraction between the suspended particles. Slowly stirring the fluid causes the particles to clump together forming “flocs.”

Coagulation is the first process in the sequence, and it is this procedure that is used to destabilize the suspended solids and to create neutrally charged micro flocs. Rather than heading straight to an expensive process of filtration or separation, facility managers can follow up the coagulation process with a flocculation procedure.

Coagulation/flocculation prior to low pressure membranes
Coagulation/flocculation is a commonly used pretreatment method for the reduction of membrane fouling; in this review it has been grouped into three typical configuration types: Type 1: coagulation + no/incidental flocculation, Type 2: coagulation + flocculation, and Type 3: conventional coagulation, based on operational conditions.
