FLUID CLEANING SYSTEM Russian patent published in 2018 - IPC C02F1/44 B01D61/12 B01D61/10 B01D61/22 C02F1/469 

FIELD: technological processes.

SUBSTANCE: invention relates to membrane cleaning and/or desalting systems for liquids and can be used in industrial, domestic and/or drinking water supplies, at industrial enterprises, liquid purification stations, in public institutions, in country and garden plots. System of cleaning fluid with a given ratio of purified and drainage fluid contains the line of source liquid 1, line of purified liquid 4, recirculation line 6 and line of drainage liquid 5. Pump 2 is installed on the line of source liquid 1. Membrane element 3 is connected to the line of purified liquid 4 and recirculation line 6. Pressure regulator 8 is installed on recirculation line 6. Liquid recirculation line 6 is connected to drainage liquid line 5. System is designed with the possibility of spontaneous maintenance of pressure not lower than that required for the implementation of the filtering process, and the ratio of the feed rate of the initial fluid to the total sampling rate of the purified fluid is always greater than 1. Pressure regulator 8 is made in the form of a mechanical spring-loaded valve. Fluid flow regulator 7 is installed on line of drainage fluid 5. Ratio of the diameters of the cross sections of the lines of the drainage liquid and the purified liquid is 4:1.

EFFECT: invention provides ergonomics and stability of the system.
