Abstract: The present invention relates to wastewater treatment facilities, and more particularly to an improved membrane bioreactor for treatment of wastewater. In one embodiment, a membrane bioreactor for treatment of wastewater includes first and second anoxic basins for anoxic treatment of such wastewater, and first and second aerobic basins for aerobic treatment of such wastewater. The bioreactor also includes a first flow path connecting the first anoxic basin and the first aerobic basin, and a second flow path connecting the second anoxic basin and the second aerobic basin, for flow of the wastewater from the respective anoxic basin into the respective aerobic basin. The bioreactor also includes a membrane chamber with a plurality of membrane tanks, the membrane chamber being arranged in series with the aerobic basins, and the membrane tanks being arranged in parallel with each other, and third and fourth flow paths connecting the membrane chamber to the first and second aerobic basins.
