To get good results in drinking water treatment, where polyelectrolytes must be avoided for their mutagenic property, low aluminium-content and high basicity PAC 9%-10% Al 2 O 3 is employed. Usually, PAC 9%-10% Al 2 O 3 is produced by simple dilution of PAC 18% Al 2 O 3, adding a basifier like Na 2 CO 3, in order to reach a final basicity of 58
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.

Different grades of PAC. PWTAG recommends a normal dosing rate of 0.1ml/m 3 of the total flow rate, which it has also described as 0.005ml/m3 as aluminium. There are now a number of different grades of PAC with aluminium concentrations between 9.5% and 18%. The concentration of aluminium is not the only consideration when selecting a grade of
Gross Formula Al(OH)xCl(3-x-2y)(SO4)y, where 0.6<x<2.5 and 0.05<y<0.5 and (x+y/2)<2.4 Composition Comments The product is formed by the action of hydrochloric and sulfuric acids on aluminium trihydroxide, to give a solution in water. Total aluminium content is 5.3% (10% as Al2O3); total strength as PAC is about 25%. SECTION 4: FIRST AID
