ULTRASONIC MEMBRANE ELEMENT Russian patent published in 2009 - IPC B01D63/16 

FIELD: chemistry.

SUBSTANCE: ultrasonic membrane element contains porous tubular carcass with semipermeable membrane layed on the substrate fixed on its inner surface and the purifying element. The latter is provided with piezoelectric element connected with ultrasonic generator which enables it to perform the alternating movement. In axial section the purifying element has the form of the rod with protrusions having streamlined dome or cone form and lead decreasing in the direction of the product movement with bigger protrusions oriented to the direction of the membrane element output.

EFFECT: efficiency enhancing of the liquids separation, increase of flow turbulisation level along with increase of dry substances concentration in the solution and solution viscosity
