    Coagulation happens when the positively and negatively charged particles are chemically attracted together. They can then accumulate (flocculation) to form larger and heavier particles (flocs). The flocs can be settled out or removed by filtration. Bacteria and viruses can attach themselves to the suspended particles in water that cause

    Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles. Coagulation is a process used to neutralise charges and form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter.

    Coagulation means to curdle; it basically refers to a chemical process in which the destabilization of non- settleable particles takes place. These particles form clump. This is done with the help of a coagulant. On the other hand, flocculation means to form flocs. It can be described as a physical or a mechanical process in which the coagulated clumps are made to join
