FILTERING MATERIAL, METHOD OF ITS MANUFACTURE AND METHOD OF FILTERING Russian patent published in 2008 - IPC B01D39/16 B01D39/06 

FIELD: mechanical engineering; filtering materials.

SUBSTANCE: group of invention relates to production of filtering materials featuring high absorbing and filtering properties, namely, to production of filtering materials on base of synthetic polymeric fibers for cleaning and decontamination of water, water solutions and other liquids. Proposed filtering material contains, as base, a polymeric fibrous material obtained by electroforming modified with particles of aluminum hydroxide attached to surface of base fibers to improved sorption properties and forming positive electric charge on material. Said filtering material is formed by modification of polymeric fibrous base received by method of electroforming. For this purpose initial aluminum-based material is applied to polymeric fibrous material and then hydrolysis of initial material is carried out, as a result of which particles of aluminum hydroxide are formed and attached to polymeric fibrous material.

EFFECT: provision of filtering material of low hydrodynamic resistance and high efficiency of filtration.
