PORTABLE SELF-CONTAINED INSTALLATION OF EJECTOR AERATION OF WATER TREATMENT Russian patent published in 2024 - IPC C02F1/18 C02F9/00 

FIELD: various technological processes.

SUBSTANCE: invention relates to reagent-free treatment of water for drinking and industrial water supply. In particular, it can be used to purify water from natural sources in field and expedition conditions in the absence of an external energy source, as well as during water treatment in case of emergencies. Installation includes working equipment installed in a technological sequence and interconnected by units, which contains a receiving tank for water, a pressure injector, a nozzle. Tank is made of a cylindrical shape, performing functions of storing contaminated water entering the installation, supplying water uniformly and in a certain volume. Injector represents at least one pipe arranged vertically to increase hydrostatic water pressure by increasing the length of the water column. Nozzle has a variable cross-section and performs the function of converting hydrostatic pressure into a water flow rate and obtaining a high-speed jet. Into the nozzle there is a built-in suction branch pipe – a self-priming nozzle for supply of atmospheric oxygen from air and its mixing with water flow for the process of water ejection aeration. All units of working equipment are connected to each other in series by means of fasteners and are installed on water treatment device with filtering bed. End part of the pressure injector with a self-priming nozzle is installed in the aeration and degassing zone of the water treatment device. Aeration and degassing zone of the water treatment device has an outlet for removal of dissolved gases from the water.

EFFECT: obtaining drinking water from natural sources in field, expedition and emergency conditions in the absence of an external energy source.
