A proposed saturator contains a saturation column 1, means to deliver liquid to the column, which includes a force-pump 3, means 23, 24 to supply carbonic acid, means to spray the liquid and means to discharge the saturated liquid from the column. Inside the saturation column 1 a pipe 2 is arranged. One of ends thereof is connected to a source 4 to deliver the liquid for saturation and to the force-pump 3. Around the pipe 2, and with a space as regards thereto, in the middle and lower parts of the column 1, a filtration netting with a cell of 25...35 ?m in size is arranged. The space between the pipe 2 and the filtration netting from above and from below is overlapped with elements opaque to the liquid. Spraying heads 6 arranged in the upper area of the column are connected to the pipe 2. The upper edge of the filtration netting is disposed at the level of 0.4...0.8 of the height of the saturation column, the lower edge in the area of the lower edge of the column. The netting is made as two net strips, made of steel or plastic, and turned as regards the axis, joint for them, as ôa pieö forming several layers. One of the strips has a cell of the above-mentioned sizes, the other a cell of 1...4 mm in size. Means for recirculation of the liquid contains an auxiliary pump 20 and back pressure valves 21, 22. The filtration netting ismade of two parts 11, 13 various in diameters thereof.
