FILTERING ELEMENT Russian patent published in 2019 - IPC B01D27/08 B01D63/06 B01D61/18 B01D61/08 

FIELD: filtration equipment.

SUBSTANCE: filter element refers to the filtration equipment. Filtering element containing a porous tubular substrate sintered from polymer particles and a filtering membrane, at the ends of the porous tubular substrate there is a cover with a hole and a bottom, characterized in that the surface of the polymer particles is coated, on the outer surface of the porous tubular substrate is applied the underlying plasma-chemical membrane of aluminum nitride particles, on the surface of the underlying plasma-chemical membrane is a filtering membrane of plasma particles of titanium, and as the polymer particles use ultrahigh molecular weight polyethylene with a molecular weight of 1⋅10⁶…8⋅10⁶ g/mol.

EFFECT: improving the fineness of cleaning fluid from mechanical impurities and the effectiveness of cleaning fluid from dissolved impurities.
