AERATION AND OXYGENATION EQUIPMENT INTENDED IN PARTICULAR FOR FISH FARM TANKS

摘要

The aeration and oxygenation equipment intended in particular for fish farm tanks (2) brings the possibility of aeration and oxygenation of water in a fish farm tank (2) without a need for a heavy weight and or any obstacles to fish harvesting. The fish farm tank (2) is fitted with a special thin-walled aeration adapter (1) with oxygenation which is not self-supporting but copies the walls (12) and bottom (11) of the fish farm tank (2). Under the bottom (13) of the aeration adapter (1) in the central part two distributing aeration rings (3, 3´) and one distributing oxygenation ring (4) are placed. The bottom (13) of the aeration adapter (1) is above the distributing aeration rings (3, 3´) and the distributing oxygenation ring (4) perforated by aeration openings (16) and oxygenation openings (17), through which air and oxygen bubbles are released into the fish farm tank (2).
