FILTRATION OZONE-MEMBRANE SYSTEM FOR WATER PURIFICATION AND DISINFECTION Russian patent published in 2023 - IPC C02F1/44 C02F1/78 C02F9/00 

FIELD: cleaning; disinfection.

SUBSTANCE: installation contains a contact tank for primary ozonation of water, equipped with a gas-liquid ejector. The ejector is connected to an ozone generator. The contact tank for primary ozonation of water in the top is equipped with a residual ozone destructor, and in the bottom it is connected directly to the outlet of the gas-liquid ejector. The contact tank for primary ozonation of water through the primary oxidized water supply pump is connected to the inlet of the secondary water ozonation unit, made in the form of two parallelly installed contact tanks of secondary ozonation of water. Each of the tanks in the bottom is equipped with its own gas-liquid ejector connected to an ozone generator. The outlet of the gas-liquid ejector is directly connected to the bottom of the secondary ozonation contact tank. The outlet of the secondary water ozonation unit is connected to a vertically installed filtration membrane module. Tubular ceramic membranes are placed in the membrane module. The bottom of filtration membrane module is equipped with its own gas-liquid ejector connected to an ozone generator. The outlet of the gas-liquid ejector is directly connected to the bottom of the filtration membrane module. The top of filtration membrane module is equipped with a fitting for draining the filtrate coming through the pipeline into the filtrate tank.

EFFECT: increasing the depth of purification of aquatic environments with the possibility of obtaining purified water of class 2 (with a pollution index of 0.2-1.0) at the outlet when purifying water of quality class 5 (with a pollution index of 4.0-6.0) and purifying water of quality class 1 (with a pollution index up to 0.2) in the treatment of moderately polluted waters with water quality class 3 (with a pollution index of 1.0-2.0).
