Flocculation - In quiescent liquids fine particles will collide because of Brownian movement. Collision may also occur when rapidly settling solids over take the slowly settling particles. As a result of these collisions larger particles are produced but in fewer number. Also the process is slow. In flocculation process, collision between the particles is improved by gentle agitation so that larger settleable particles are produced.
Flocculation is a process of gentle and continuous stirring of coagulated water for the purpose of forming flocs through the aggregation of the minute particles present in the water. It is thus the conditioning of water to form flocs that can be readily removed by settling or filtration.
