AUTOMATIC REGENERATED FILTER Russian patent published in 2016 - IPC B01D29/52 B01D29/66 

FIELD: treatment plants.

SUBSTANCE: invention relates to filtration of fluids and can be used in various industries, where cleaning fluids of mechanical impurities in wide range of subtleties filtration in continuous process of filtration is required.
