DEVICE FOR FILTRATION OF SEWAGE WATERS WITH REVERSE OSMOSIS MEMBRANE PURIFICATION SYSTEM Russian patent published in 2014 - IPC B01D35/16 B01D61/02 B08B9/00 

FIELD: chemistry.

SUBSTANCE: device contains a receiving reservoir, the main forcing pump, an input three-way high-speed valve, a connecting pipe for input of water to be purified, a membrane unit, a connecting pipe for output of the purified sewage, an output three-way high-speed valve and a reservoir of the purified sewage, successively connected to each other by a pipeline for operation in a sewage purification mode. In their turn, the reservoir of the purified sewage, an additional pump, the output three-way high-speed valve, the connecting pipe for output of the purified sewage, the membrane unit , the input three-way high-speed valve and a settling tank are successively connected by an additional pipeline to operate in a mode of reverse osmosis membrane purification. The membrane unit is connected to an ultrasonic generator. A control unit, provided in the device, is connected to the input and output three-way high-speed valves, additional pump and ultrasonic generator.

EFFECT: increased efficiency of periodic purification of filtering elements and increase of their service term.
