Coagulants Used in Water Treatment | ChemREADY
Coagulants Used in Water Treatment | ChemREADY

With ,coagulants,’ positive charge, the negatively charged particles in the water are neutralized. This causes the suspended solids in the water to bind together into larger flocs. These larger flocs begin to settle at the base of the water supply. The larger the size of the particles, the quicker the floc settles.
