METHOD FOR PRODUCING ALUMINOSILICATE HYBRID REAGENT FOR TREATING NATURAL AND INDUSTRIAL WASTEWATER AND METHOD OF TREATING NATURAL AND INDUSTRIAL WASTEWATER WITH THIS REAGENT Russian patent published in 2018 - IPC C01F7/74 C02F1/52 C02F1/28 C01B33/26 

FIELD: technological processes.

SUBSTANCE: group of inventions can be used in the processing technology of aluminosilicate raw materials to produce an aluminosilicate hybrid reagent for use in water treatment and water treatment systems. Method for preparing aluminosilicate hybrid reagent in the form of aqueous solutions comprises treating the alkali aluminosilicates with an aqueous solution of 8–10 % sulfuric acid with constant stirring with a low-speed stirrer with a speed of 40–80 rpm for an hour, separating the liquid phase from the solid and adjusting the ratio of aluminum to silicon in the resulting solution of the reagent so that, in terms of their oxides, is 0.50–0.75. Basis of the structure of the produced aluminosilicate hybrid reagent are silicon-oxygen tetrahedra (fig. 1, a) and various combinations of these structural units (fig. 1, b, c, d, e). Method for purifying natural and industrial wastewater includes treating the water with the resulting reagent as its aqueous solutions.

EFFECT: inventors ensure the use of low doses of the reagent to obtain a high degree of purification by using a highly effective reagent.
