A wastewater treatment system includes a biological treatment plant and an auxiliary, non-biological treatment plant. The auxiliary plant receives overflow, which can be sanitary sewer overflow, combined sewer overflow or strictly storm overflow. Treatment is by coagulation and membrane separation, removing most bacteria. Following treatment the outflow can be discharged to streams.

Membrane wastewater treatment of combined sewer overflows and sanitary sewer overflows

A wastewater filtration device, the device including a tank having end walls, a first screen rotationally mounted adjacent one tank end wall, and a second screen rotationally mounted adjacent the other tank end wall, adjacent the fine screen. The device further includes an inlet in one end wall adjacent the fine screen and into the fine screen, and an outlet in the other end wall adjacent the second screen and out of the second screen. A dividing wall is between the first screen and the second screen, so that water in the inlet flows into the first screen, and then through the first screen out into the tank, around the dividing wall, and then through the second screen into the outlet.
