METHOD OF LIQUID TREATMENT WITH SIMULTANEOUS CLEANING OF FILTER ELEMENT Russian patent published in 2016 - IPC B01D29/62 

FIELD: wastewater treatment plants.

SUBSTANCE: invention relates to filtration, namely, to methods of filtering elements regeneration, and can be used in fluids cleaning of suspended and other impurities in industrial water supply systems. Method of liquid treatment at simultaneous cleaning of a filter element consists in that the gap of cone-shaped section is made between walls of the housing of the filter and the filter element, fed fluid for treatment is divided into two flows, one of which is supplied for cleaning through the filter element, and the second one is used as flushing fluid for the filter element from contamination, purified liquid is sent to the consumer after passing through the filter element, without interruption of fluid cleaning, high-voltage discharge is periodically transmitted into a mesh of the filter element by means of a discharger, installed inside the filtering element, contamination is washed out in the bin-cyclone by flushing fluid flow, then it is pumped by an ejector at the filter input, and it is returned into the washing cycle of the filter element, sludge is accumulated in the bin-cyclone, from where it is removed at a time.

EFFECT: technical result is improvement of cleaning quality of the filter element of impurities and contamination.
