MEMBRANE FOR REVERSE OSMOSIS Russian patent published in 2015 - IPC B01D61/08 B01D63/10 

FIELD: machine building.

SUBSTANCE: reverse osmosis (RO) module to produce superpure water contains a pipe with bottom and lid, and located in pipe RP membrane with permeate gathering pipe. RO membrane by the end section is inserted in the membrane flange, and is sealed relatively to it by the ring seal, and flange is secured on the module bottom and has telescoping preventing sprocket that is integral part of the flange. The module bottom has inlet hole for the feed water that ends in the ring slit under the membrane flange, the outlet hole for concentrate that ends radially in the membrane flange under the membrane, and hole connected with end of the permeate gathering pipe. The invention ensures minimization of the dead areas in the structure, their presence results in bacterial pollution and creation of the biological deposits. Besides the invention provides for the possibility of use in RO units with various capacity.

EFFECT: improved design.
