FIELD: filtration processes. SUBSTANCE: proposed porous ceramic filter has secondary distant elements forming net of branched-off passages for avoidance of hydraulic impacts at regeneration . At least one of secondary distant elements is opposite and coaxial relative to drain hole and is separated from it by free space; minimum size of cross section of secondary distant element is no less than diameter of drain hole. EFFECT: enhanced reliability of filter and avoidance of hydraulic impacts. 2 cl, 2 dwg
