Abstract
A flocculant composition comprises a polyaluminium calcium magnesium chloride or chloride sulphate gives effective turbidity reduction and transmissivity increase in waters, especially in waters having a hardness no more than 120 mg/l CaCO3. The composition is produced by the reaction of aluminium chloride in an acidic aqueous medium containing chloride and/or sulphate ions and also containing one or more magnesium carbonate-containing minerals such as dolomite. The aluminium chloride may be aluminium chloride contaminated with organic impurities as a result of use as a catalyst for organic transformations such as the alkylation of aromatic or aliphatic compounds by means of the Friedel-Krafts reaction.
