FILTERING LOADING FOR THE COMPLEX PURIFICATION OF THE WATERS Russian patent published in 2007 - IPC B01D39/16 B01J47/02 B01J39/18 B01J41/12 C02F1/42 

FIELD: water-supply engineering; methods and devices for water purification.

SUBSTANCE: the invention is pertaining to the field of the sorption purification of the waters both the surface water and the artesian water-supply sources. The sorption-filtering loading for complex purification of the waters contains the low-base anionite, the low-base anionite impregnated with the humus substances, the coal or sand, the inert polymeric substance with the density not exceeding the densities of the other components of the loading, the strong-acid cationite in Na- and-or K-form, and also the low-base anionite impregnated with iron and the high-base anionite. The contents of the components in the loading constitutes(in mass %): the sand - 4-6, the inert polymeric substance - 4-6, the low-base anionite - 0.2-15, the low-base anionite impregnated with the humus substances - 0.2-15, the high-base anionite - 0.2-15, the low-base anionite impregnated with the iron - 0.2-15, strong-acid cation-exchanger - the rest. The invention ensures the high-degree purification of the water from the ions of the metals especially of Fe and Mn, the hardness salts, aluminum, the organic impurities and hydrogen sulfide. One loading can be used for purification of not less than 50000 specific volumes of water.

EFFECT: the invention ensures the high-degree purification of the waters from the ions of the metals especially of Fe and Mn, the hardness salts, aluminum, the organic impurities and hydrogen sulfide and one loading can be used for purification of not less than 50000 specific volumes of the water.
