a process that alters the surface charge on dispersed
colloidal particles in a liquid so that they are able to
agglomerate; the first stage in floc formation
the agglomeration of coagulated particles to form a
floc which can settle or float; may be assisted by
biological, chemical or mechanical mean
After flash mixing, the coagulant chemical is added. It helps in neutralization of the particles in the water. So the particles come closer and make large clumps
It is the last step. In the flocculation process, the particles formed by coagulation are gently mixed together with flocculent. This is done in a flocculation basin with the use of mixing blades. Thus this process makes the flocs. These are then allowed to settle down in the sedimentation
