Mobile sewage treatment assembly, to fit into a container for transport, has a single injection unit with two flotation basins to treat the sewage with streams of micro bubbles

摘要

The mobile sewage treatment and flotation assembly has a sewage feed (17) into two flotation basins (2,3), for the sewage (7) to flow in at the side from below. An injection unit (4) delivers a gas under a high pressure, and preferably air or highly saturated water under pressure to give a stream of micro bubbles through release valves (5,6). The floating matter (10) is removed (9), and the treated water is taken off (8). The single injection unit and the two flanking horizontal and quadrilateral flotation basins are arranged on the floor surface area of a standard container (1), to give a recirculating flow in the basins.
