The results of treatment of solutions with high sulphates concentration and the high rate of water hardness are given. It is shown that significant reduction of secondary pollution by chlorides is achieved through integrated use of aluminium hydroxchloride and sodium aluminate coagulants. It was found that the efficiency of water purification from sulphates and water softening can be increased with the carbon dioxide processing.
