FIELD: process engineering.
SUBSTANCE: invention relates to concentration of solutions by baromembrane microfiltration, ultra filtration and reverse osmosis and may be in microbiology, chemical and food industry, etc. Proposed apparatus consists of sections coupled by flanges bolted together and made up of two membranes arranged in cylindrical shells and alternating with seal gaskets and laid on finely porous back layers resting, in their turn, on rings with drain material arranged there between. Note here that thin silicon inserts are arranged inside said seal gaskets and between two metal plates welded in rubber and connected with ultrasound-frequency oscillation generator.
EFFECT: higher efficiency, power savings.
