METHOD OF CLEANING WATER AND COMPOSITE ADSORPTION MATERIAL Russian patent published in 1999 - IPC

FIELD: water treatment. SUBSTANCE: material, containing packed mixture of granules and fibers, preferably granulated activated carbon and activated carbon fibers, is used as tap water cleaning filter. Activated carbon fibers fill space between activated carbon granules. Sizes and relative amounts of granules and fibers are chosen to accelerate water cleaning as compared to cleaning of water with conventional filters. In cases of considerable idle periods, packed mixture of granules and fibers exhibits improved capability of restoring adsorption properties. EFFECT: enhanced water treatment efficiency. 17 cl, 4 tbl
