DEVICE FOR AERATION OF LIQUID (VERSIONS) Russian patent published in 2018 - IPC C02F1/74 C02F3/14 C02F7/00 B01F3/04 

FIELD: chemistry.

SUBSTANCE: system for aeration of water in the upper layers at a constant water level in the tank comprises a frame, a fastening, at least, one compressor, at least, one air supply line, and, at least, one aerator. The frame is made in the form of a prism or a cylinder, on the upper base of which there is a fastening. At least, one aerator is located on the lower base of the frame. The fastening is made with the possibility of rigid fixing the frame in the tank. The device for aeration of water at variable level comprises a skeleton (1), at least, one compressor, at least, one air supply line (3), at least, one float (2), and, at least, one aerator ( 4). The frame (1) is made in the form of a prism or cylinder, on the upper base of which, at least, one float (2) is placed. At least, one aerator (4) is located on the lower base of the prism or the cylinder.

EFFECT: invention makes it possible to shorten the duration of the water treatment process by aeration of its upper layers in the range of 2 to 4 m from the water surface.
