FIELD: separation, concentration and purification of solutions.
SUBSTANCE: distinctive feature of the electric baromembrane apparatus is that on the blind end surface of the cylindrical shell of the housing there is a through hole with installed in it on thread turbulizing module of "volute" type and nozzle for supply of separated solution, and the cross-shaped partition along the entire length is perforated with round holes arranged in three rows in a staggered order. At the same time in the external tube there is a polymer perforated partition with oval holes arranged at angle of 90 degrees throughout the length of the outer and inner tubes, and in the fixing gasket there are holes made in the form of two half-moons with five circles in each. Besides, films with notches deepened to half of its thickness are square in shape.
EFFECT: improved hydrodynamics of flow, reduced effect of concentration polarization and reduced hydraulic resistance.
