The process of coagulation typically involves several stages, starting with the addition of the coagulant to the water. This addition is usually followed by rapid mixing to ensure that the coagulant is evenly distributed and can interact with impurities. After the initial mixing, the water undergoes flocculation, a gentle stirring process that allows the newly formed flocs to gather and grow larger. Finally, the water goes through sedimentation, where the flocs, being heavier than water, gradually settle at the bottom of the treatment tank, leaving clearer water above.
