    Abstract: The object of the present invention is a method of mixing a liquid with a gas, in a gas-tight multi-tube reactor, and a device for mixing liquid with gas. The multi-tube reactor disclosed herein is used for mixing liquids, at least one of which is in a form of a gas or emits a gas, especially for introducing process gases into the liquids being treated, whether for oxygenating water or wastewater and sewage sludge. Furthermore, the multi-tube reactor according to the invention may be used in water treatment and wastewater disinfection technologies utilising ozone and/or hydrogen peroxide. It may also be used in existing wastewater treatment plants, as well as for the oxygenation of water in various bodies of water. The device is in a form of a multi-tube reactor provided with a main mixing chamber having a front part, a rear part, a bottom and a ceiling, wherein at least one propulsion injector nozzle, located at the bottom of the main mixing chamber, is introduced into the front part of the main mixing chamber, and an additional mixing chamber is led out of the rear part of the main mixing chamber, the additional mixing chamber having at least two times smaller cross-sectional area than the cross-sectional area of the main mixing chamber of the multi-tube reactor, characterised in that at the opposite end of the main mixing chamber (2), in the additional mixing chamber (5), a propulsion injector nozzle (3) is installed, directed with its tapering end towards the outlet from the additional mixing chamber (5), and from the ceiling (2.4) of the main mixing chamber (2), at least one bypass connection (6) is provided, which is connected at its other end to the additional mixing chamber (5).
