Poly Aluminium Chloride - PAC These compounds have the general formula (Al n (OH) m Cl (3n-m) )x and have a polymeric structure, totally soluble in water. The length of the polymerised chain, molecular weight and number of ionic charges is determined by the degree of polymerisation.

PAC applications. Water treatment - The poly aluminium chloride (PAC) is used for settling of solid particles present into drinkable waters and for the flocculation of civil and industrial effluents. It has also a high antibactericide effect, due to the presence of chlorine into the product formula, and can be utilized for large range of pH and with higher turbidity.
