Device for the flow-through separation of oil from water with meander-shaped flow

A device for the flow-through separation of oil from water consists of a tank with an inlet and outlet, and with baffles extending downwards and upwards into the water to be cleaned so that a meander-shaped flow is obtained through the tank. Overflow openings are provided in the upper zone of the tank for discharge of the separated oil. The device is designed in such a way that the separation is more complete and quicker than with known arrangements, and/or that the required cleaning is achieved even with a single pass. According to the invention, the top edges of the baffles directed from the bottom toward the top are at the same level as the bottom edges of the overflow openings so that in each case two consecutive chambers extending over the entire liquid level are formed, of which the upper zones are connected with one another in pairs but are otherwise separated from one another by baffles, in which case the lower zone of each second chamber is connected with the following chamber of the next pair. A tank with a volume of about 2 m3 is appropriate for a throughput of 2000 l/h, indicating that the device of the invention can be made relatively small while still having good efficiency. This enables the device to be transported easily to cleanup sites. 4 figs
