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.

Abstract: The present invention relates to odor control systems and more particularly to a system and method for treating air to remove odors and return the treated air to the atmosphere. In one embodiment, an odor control system includes an ionization assembly, which has several ionizers producing an ionized air flow. The system also includes a foul air intake providing a foul air flow, such as from a wastewater treatment or other processing plant. The system also includes a reaction chamber, which provides a reaction volume for reaction of the foul air flow and the ionized air flow. The ionized air reacts with constituents in the foul air to treat the foul air for release of treated air to the environment.
