摘要

The device (2) has a container (20) cooperating with a suction device (24) of pollutant liquid (15) for collecting the sucked pollutant liquid, and another container (21) cooperating with a pressurizing device (32). A filter element (30) is arranged in a flow direction (33) before the latter container, and a connection line (31) connects the former container with the filter element. The filter element has a filtering surface provided in a mantle surface and a cover undetachably connected with the mantle surface. A holding device mechanically supports the filter element at the latter container.
