FILTERING ELEMENT FOR SEPARATION AND CONCENTRATION OF LIQUID MEDIA Russian patent published in 2019 - IPC B01D63/08 B01D71/00 

FIELD: separation.

SUBSTANCE: invention relates to apparatus for separating and concentrating liquid media and can be used in making devices using semipermeable membranes for removing mechanical, colloidal and dissolved inclusions with size of 0.1 mcm and higher, including for chemical, biotechnical industry, as well as in water treatment systems, pharmaceutics. Filtering element for separation and concentration of liquid media, which is a membrane cassette module, consists of filtering packs equipped with units for supply of liquid medium, output of concentrate and filtrate in form of through holes, each of which includes tightly connected to each other and single-piece case formed by sealing adhesive polymer material, concentration net, separation frame, track membrane and separating-drainage meshes arranged between them. Units of liquid medium supply and concentrate and filtrate outlet are made with two or three radii of rounding, characterized by size of inscribed angle of 10–170°. Track membranes used are flat track membranes with thickness of 5–100 mcm, number of pores 5×10⁵–5×10⁸ per 1 cm². Number of filtering packs ranges from 1 to 50.

EFFECT: technical result is longer service life of filter element, possibility of sterilizing filter element, high manufacturability of developed filter element, which consists in its multiple use.
