A liquid treatment plant employing a gas - liquid mass transfer process includes a circulating pump for a liquid within a tank, and an injector pump which operates to entrain air in the liquid delivered by the circulating pump prior to return of the liquid/air mixture to the tank by way of a mixing pipe and a deflector which disperses the mixture. The cross-section area of the injector pump outlet is between 1.05 and 1.4 times that of the injector pump nozzle, and the cross-sectional area of the mixing pipe is between 4 and 11 times that of the injector pump nozzle.
