REVERSE OSMOSIS PLANT Russian patent published in 2023 - IPC B01D61/02 

FIELD: jet devices.

SUBSTANCE: invention relates to a wider group of jet devices that implement the ejection principle of operation, and can be used in almost all areas of technology. The claimed device includes membrane elements connected at the inlet to the water inlet line for purification, which includes a pressure gauge, a cartridge filter, a pressure switch, a pressure gauge, an electrical conductivity sensor, an electromagnetic valve, a jet pump, a check valve, an electric pump, a pressure switch, a pressure gauge and a valve connected between themselves by pipelines and separating the initial solution into permeate and concentrate, which, in turn, is the initial liquid for the membrane element, and the concentrate at the outlet of the membrane element is the initial liquid for the membrane element. The concentrate line includes a pressure gauge, a valve and is divided into three pipelines, one of which includes a valve, a rotameter, a check valve and is connected to the branch pipe of the active medium of the jet pump. The second pipeline includes a valve, a rotameter, a third pipeline with a solenoid valve and is connected to the second pipeline, together constituting the concentrate outlet line. The permeate line includes a valve, a check valve, an electrical conductivity sensor and a rotameter.

EFFECT: increasing the productivity of the reverse osmosis plant and increasing its energy efficiency, due to the possibility of choosing a high-pressure pump with less energy consumption.
