A method and device for treating liquids. |
摘要 |
The invention concerns a method and a device for treating liquids, such as wastewater. According to the invention the liquid is transported by help of a pump (10) from the lower area of a tank (1) through a vertically directed pipe (3) up to a 180 degree bend (5) located above the water surface and where air is sucked in through openings in the bend. The air-liquid mixture is then guided through a second pipe (6) having its outlet (7) close to the tank bottom (2). In this area the flow is once more linked 180 degrees and is directed through a third pipe (8) ending close to the water surface. Thanks to the linking through the pipe (8), a decrease of the static head is obtained against which the pump (10) operates. <IMAGE> |
