A device for clarifying wastewater, preferably on ships, having the following features: A tank for untreated water is connected to a pressure tank via a macerator and a feed pump. The pressure tank is connected to a compressed air source so that the untreated water in the pressure tank is saturated with air. The pressure tank is connected via a line to a decompression tank in which the flotate and clarification water can be separated from each other. An expansion valve is inserted in the line, and a dosing pump for flocculant is connected to the line between expansion valve and decompression tank. |
