For water Treatment:

Flocculants are used in water treatment. The addition of flocculants to raw water causes colloids and other suspended particles to stick together and form heavier particles (floc) which will be removed by the sedimentation or filterability.

PAC is also used in reducing the need of pH adjustment and is often employed in the place where the pH of the receiving stream is higher than 7.5. PAC is also used in the pulp (or paper) industry as a size bonding agent, drainage work aid and surface trash scavenger.
