FIELD: chemistry.
SUBSTANCE: invention relates to devices for water purification by principle of reverse osmosis and can be used for preparation of dialysing fluid. Device for production of highly pure water by principle of reverse osmosis contains filter of reverse osmosis, which is divided into primary chamber and secondary chamber by means of membrane of reverse osmosis, and pump, which pumps liquid through primary chamber, as well as located upstream from membrane of reverse osmosis, necessary for creation of pressure in primary chamber hydraulic resistance. In primary contour there is, at least, one purification chamber with devices for water softening and discharge valve, and flow of liquid in primary contour is regulated by means of valve and primary contour is made with possibility of washing its volume in flooding type manner by opening valves.
EFFECT: increased efficiency of purification and reduction of energy consumption.
