Poly Aluminium Chloride

Poly Aluminium Chloride is the product of the batch reaction between solid Aluminium Hydroxide (AL(OH)3) and liquid Hydrochloric acid (HCI). Aln(OH)mCl3n-

Poly aluminium chloride is used extensively in the food manufacturing industry as a coagulant.  It brings the solid matter in a waste stream out of suspension, allowing the flocculent, selected from GPC’s range, to bind the particles together and remove them from the effluent.


It is available in 1000L IBC, 2.5L, 10L and 25L kegs or Multiple 1000 L Pump Overs.

Reduce Sludge

PAC 18 (Poly Aluminium Chloride) is based on highly charged aluminium which results in lower dosage and therefore reduces sludge volume and pH adjustment demand.

Improves Solids

It also improves solids and/or phosphorous removal over conventional coagulants.
