THIN-LAYERED SUMP MADE AS PER CROSS CIRCUIT Russian patent published in 2015 - IPC B01D21/02 E03F5/14 

FIELD: construction.

SUBSTANCE: includes a housing, a sludge collector and a system of water supply trays with water distribution through a water discharge, a water supply tray with a jet guide wall, which is installed in the upper part of the housing, with that, the above jet guide wall is made in the form of a bent plate consisting of two vertical sections and one horizontal section adjacent with a gap to the vertical plate of the water supply tray. In the lower part of the housing there installed under the water supply tray is a sludge collecting part of the housing adjacent to the bottom part made with an inclination towards the sludge collecting part. On the side opposite to the water supply tray there located is a water discharge system made in the form of a vertical plate, the upper part of which is located on the water level of the sump housing, and the jet guide plate with a bend towards the rear wall of the housing, in which two drain tubes located on different levels from upper edge of the housing are mounted. The housing consists of two parts, the first one of which, which is connected to the water discharge, is made in the form of a sand collecting chamber with a sand collector in the lower part, and the second part of the housing includes a thin-layered unit made as per a cross circuit and located in horizontal plane parallel to the water discharge axis, in the lower part of which the sludge collector is located. A jet distributing device is located perpendicular to the water discharge axis and separates the first and the second parts of the housing from each other by means of horizontally located plates. A clean water outlet branch pipe is located in the second part of the housing.

EFFECT: improving waste water cleaning efficiency.
