| Popis: | The paper presents four study versions: an aeration process and three stationary water oxygenation processes. In the aeration process, atmospheric air (21% O2 and 79% N2) is introduced into a pool of water. In the oxygenation process are introduced successively: - A gaseous mixture of atmospheric air and a certain volume of oxygen taken from a cylinder. - Low nitrogen air. - A mixture of atmospheric air and ozone. For the four versions, the experimental installations, the calculation results and the experimental obtained ones in case of the change of the dissolved oxygen concentration in the water are exposed. The electricity consumption for the four versions is analyzed at a certain time, when the initial concentration of dissolved oxygen in the water reaches the saturation concentration. |
