MEMBRANE FILTERING ELEMENT FOR AGGRESSIVE LIQUIDS DECONTAMINATION Russian patent published in 2010 - IPC B01D63/06 B01D71/02 B82B1/00 

FIELD: mechanics.

SUBSTANCE: invention relates to a membrane filtering element for aggressive liquids decontamination that consists of a hollow porous cylinder 1, a bottom 3 and a cover 4 mounted on the hollow porous cylinder butt-ends. Applied onto the outer surface of the hollow porous cylinder 1 is a membrane 5 fabricated of a nanostructured ceramic material represented by aluminium oxide (α-Al₂O₃) formed in a flow of erosive aluminium plasma in an oxygen medium. Additionally, the filtering element contains a perforated tube 2 mounted inside the hollow porous cylinder 1.

EFFECT: invention enables provision for efficient decontamination of aggressive liquids within the limits of the preset operation life and allows of repeated regeneration of the filtering element.
