SORPTION-FILTERING CHARGE FOR COMPLEX WATER PURIFICATION Russian patent published in 2022 - IPC B01D39/16 C02F1/42 B01J41/12 B01J39/05 

FIELD: sorption-filtering charges.

SUBSTANCE: invention relates to the field of sorption water purification, namely to sorption-filtering charges that can be used to purify water from non-centralized water supply sources, in particular surface water, water from springs, wells, as well as artesian wells and wells for deep and fine sand. The charging contains components with the following ratio, wt.%: low-base anionite of macroporous structure - 5-15; low-base anionite of macroporous structure impregnated with fulvic acid or a mixture of fulvic and humic acids, and/or a mixture of salts of these acids - 5-15; sand - 4-8; inert polymer material with a density not higher than the density of other components of the loading - 4-8; highly basic gel anionite impregnated with permanganate anions or manganate anions - 15-25; and strong acid cationite - 29-67. The size of granules of low-base anionite, impregnated low-base anionite, strong acid cationite and impregnated high-base anionite is 0.4-0.6 mm.

EFFECT: invention enables to increase the degree of complex purification of water from non-centralized water supply sources from iron, manganese, aluminum, hydrogen sulfide, hardness salts, organic impurities and mechanical particles with their simultaneous presence in the treated water is provided.
