WATER FILTRATION PLANT Russian patent published in 2024 - IPC C02F1/00 B01D29/50 B01D29/66 

FIELD: water treatment.

SUBSTANCE: invention relates to water treatment and can be used in natural water treatment systems for household, industrial and agricultural water supply. Apparatus consists of two series-connected filters providing a stepped water treatment mechanism. First filter cuts off the suspension of particles up to 20 mcm, the second filter purifies water from smaller particles with size of up to 5 mcm. Filtration elements of filters are made of stainless steel frame, on which a dense layer of stainless wire is wound, density of winding can be from 20 to 5 microns. System of flushing of filtering elements of filters is made by means of two valves with electric drives, which redirect water flows in reverse direction to filtering elements of filters. One of the taps is installed at the inlet of the water supply pipeline and is connected to series-connected filters and the pipeline for supplying purified water to the water supply system of consumers. Second valve is also connected to the water supply pipeline and the flushing water pipeline. Flushing holes of each filter are connected via solenoid valves with electric drives with drain pipe. Filtering elements washing system is controlled by control unit to which two electrically driven valves and two electrically driven solenoid valves are connected. Flushing of filtering elements of filters is performed due to pressure of water, washing away and removing impurities from surface of filtering elements through flushing holes of filters into drainage pipe. Water supply in the mode of filtering elements washing to the consumers water supply system is not stopped.

EFFECT: improving water quality, increasing the efficiency of the automatic cleaning system for filter elements, simplifying installation, ensuring autonomy that does not require periodic maintenance.
