FLAT-CHAMBER ELECTRIC BAROMEMBRANE APPARATUS Russian patent published in 2010 - IPC B01D61/42 B01D61/46 

FIELD: process engineering.

SUBSTANCE: invention relates to separation, concentration and purification of solutions and can be used in chemical, textile, food and other industries. Proposed apparatus comprises flanges, inlet and outlets channels of separated solution and permeate discharge channels, DC feed source, alternating dielectric chambers of the casing jointed via ledge-recess joint and reverse-osmotic membranes. Electric conductor lead-ins are arranged on both sides of every casing chamber. Unipolar porous plate electrode with drain grid and casing dielectric chamber form the channel to discharge cathode or anode permeate via channels made on casing dielectric chambers. Note here that electrically conducting mesh-turbuliser runs in all inter-membrane channels communicated via overflow elliptic openings. Besides dielectric element is applied on all crests of said mesh at the points it stays in contact with the membrane surfaces. Said unipolar electrode and mesh-turbuliser make anode or cathode, respectively, depending upon connection manner, i.e. "plus" or "minus".

EFFECT: increased membrane cathode or anode, higher quality and efficiency of solution separation.
