ELECTROBAROMEMBRANE DEVICE OF COMBINED TYPE Russian patent published in 2022 - IPC B01D61/18 B01D63/06 B01D63/08 

FIELD: filtration.

SUBSTANCE: invention relates to the field of separation, concentration, and purification of solutions by electromicrofiltration, electroultrafiltration, electronanofiltration, electroosmofiltration. An electrobaromembrane device of a combined type consists of two covers with fittings for input of a separated solution, output of retentate, removal of permeate and air supply for injecting pressure into a chamber for permeate of the first stage, a case of a flat-chamber module, support rings, a channel for removal of permeate from flat membrane elements, a check valve, a drainage mesh, porous substrate, membranes, a float level gauge, a tubular membrane module, gaskets, sealing fillings, a bayonet ring. The tubular membrane module of the second stage consists of alternating near-cathode and near-anode membranes, tubular porous substrates, near-cathode and near-anode drainage meshes connected to plates by electrode-cathode and electrode-anode, contacting with terminals for supplying direct electric current – cathode and anode, made in the form of cylindrical pins, near-cathode and near-anode chambers for permeate of the second stage, divided by a dielectric partition, fittings for removal of near-cathode, near-anode permeate of the second stage, a seal of the tubular membrane module, a plug, and a cuff.

EFFECT: differentiational isolation of ions in flows of near-cathode and near-anode permeate at the second stage of separation, reduction in hydraulic resistance in a volume unit of a device, increase in the quality and efficiency of solution separation.
