ROLL-TYPE ELECTRIC BAROMEMBRANE APPARATUS Russian patent published in 2023 - IPC B01D61/18 B01D61/46 B01D63/06 

FIELD: separation; concentration; purification of solutions.

SUBSTANCE: electric pressure membrane apparatus is disclosed, in which a screw cruciform partition is located inside a perforated tube; on the inner surface of the tube there are four semi-elliptical screw grooves running along the entire length of the screw generatrices and distributed from the horizontal axis at angles, and four through elliptical screw grooves. The outer tube has a helical partition and a polymer perforated helical partition with hyperboloid holes, located along the entire length of the outer and inner tubes and located, respectively, from the horizontal axis in the section at angles. On the inner surface of the inner tubes there are four semi-elliptical helical grooves running along the entire length of the helical generatrices and distributed from the horizontal axis at angles, and a through elliptical helical slot.

EFFECT: increased productivity of the apparatus and the quality of separation of solutions.
