FIELD: chemistry.
SUBSTANCE: invention can be used to treat low-turbidity water, in treating water for household purposes from natural surface sources, in treating industrial waste water with high content of a dispersed phase from suspended matter, petroleum products, fat, protein and other impurities of mineral and organic nature. The method is carried out by mixing (0.1-0.2)% aqueous solution of a weakly charged polycationite with a cationic charge (1.65-9.23) with an aluminium salt, taken in the form of aluminium pentahydroxochloride sol in molar ratio Al3+:polycationite link equal to (2-6:1).
EFFECT: method improves efficiency of using high-molecular polyelectrolytes and reduces the dosage thereof while improving degree purity of water.
