WATER AERATION DEVICE IN MEMBRANE TANK Russian patent published in 2022 - IPC C02F1/74 B01F35/513 B01F23/23 

FIELD: water saturarion.

SUBSTANCE: invention is intended to saturate water with atmospheric oxygen in iron removal and water treatment systems. The device contains a distribution head 4, which includes an interconnected mounting pipe 5, a safety group pipe 9, an air removal pipe 7 connected to an air separation valve 8, and a separate air pipe 13 with an air duct connected to it for supplying air from the compressor. The air duct is made in the form of a tube 10 with an atomizer 14 at the end. The tube 10 is placed coaxially with the mounting pipe 5 and passes through it and the upper pipe 6 of the membrane tank 1 with a gap 12, which ensures free passage of air between the walls of the tube 10 and the pipe 6. The atomizer 14 has a shape with smoothed corners, which excludes damage to the membrane 15 in the tank. The atomizer 14 is located in the lower quarter of the internal cavity of the membrane tank 1. The distribution head 4 is installed on the upper branch pipe 6 of the membrane tank 1. The compressor is electrically connected in parallel with the water pump. Saturation of water with air oxygen is carried out in a membrane tank and the use of a separate aeration column and a water flow switch is not required in the water iron removal system.

EFFECT: improving the efficiency of the device.
