PolyAluminium Chloride (PAC) is commonly used in water treatment process. PAC is a good flocculating and coagulating agent and is commonly used when treating industrial water and is increasingly being used when treating drinking water. PAC reacts to form insoluble aluminium poly-hydroxides which precipitate to form flocs. The flocs attract suspended solid which can then easily be removed and separated from the solution.
