Abstract

FIELD: inorganic salt engineering. SUBSTANCE: aluminium hydroxo-salt-based coagulant, useful in the water treatment, waste water and solutions' purification, and other industrial applications, is prepared by interaction of an aqueous solution of aluminium sulfate with calcium hydroxochloride or chlorocarbonate taken in amounts producing the product with 33-75% of basicity. The calcium sulfate precipitate formed is separated from the product and undergoes a water-acid treatment for 0.5-1 h at a weight proportion of liquid to solids from 1.5: 1 to 1:1 and under pH value within the range 0.8-2.0. The washing water is utilized then in the preparation of the aluminium sulfate solution and in the water-acid treatment. EFFECT: simplified process, reduced losses of the product with calcium sulfate precipitate, the latter being obtained in a form fit for a further conversion. 3 cl
