DESALINATION PLANT FOR REVERSE OSMOSIS Russian patent published in 2019 - IPC C02F1/44 B01D61/08 B01D36/00 C02F103/08 

FIELD: water treatment.

SUBSTANCE: invention relates to purification and desalination of sea water. Desalination plant of reverse osmosis includes frame body 1, a reverse osmosis membrane 4, hydraulic drive 2, a hydraulic distributor of washing 6, a hydraulic distributor of preservation 7, container 8 with a liquid preservative, unit for filtration of mechanical impurities of supplied sea water, consisting of several filters 9, 10, 11 of mechanical impurities. Each mechanical impurities filter 9, 10, 11 includes a hydraulic distributor support 12, 13, 14 installed on the frame body frame 1 and a filter element. Through channels of support-distributors 12, 13, 14 of mechanical impurities filters 9, 10, 11 are in-series connected, forming common through channels of mechanical impurities filtration unit: for sea water, removal of particles delayed by filtering elements, and filtrate discharge. Through channel for feed of sea water of hydraulic distributor of flushing 6 and channel for removal of preserving agent of hydraulic distributor of preservation 7 are connected to single through channel for sea water of filtration unit of mechanical admixtures from opposite sides. Through channel for withdrawal of concentrate of hydraulic control valve 7 is connected with single through channel for removal of particles of filtering elements of filtration unit of mechanical impurities.

EFFECT: invention provides for compact design of plant with periodic washing of its blocks and elements, as well as preservation during pause.
