Abstract

Equipment for gassing a liquid, preferably for the ozonization of water, comprises two gassing stages. In the first gassing stage, a part of the liquid to be treated and the process gas are introduced by means of a submerged gas distributor (6) into a bubble column having an inner chamber and an outer chamber. The major part of the liquid is fed to the second gassing stage which has a shower tray and is located above the first gassing stage. From the shower tray, the "depleted" process gas leaving the two chambers comes into interaction with the "fresh" liquid. Gassing of the liquid at a high absorption efficiency of up to about 95% is achieved in this technically simple and at the same time economical way.
