摘要： A screen configuration is provided for the extraction of wastewater from a wastewater reactor, while precluding the entry of biological support media. The screen may be formed as a tubular structure, and may be drum-like or have wings in a T-shaped configuration. A flow modifier within the screen may include one or more tubes extending into the screen and forming annular sections around the tubes. Flow through the screen, then, is directed around the inner flow modifier tubes and through the tubes. The resulting pressures and flow velocities are such that slot velocities through openings in the screen are generally constant along the length of the screen, and the flow is more efficiently distributed. The screen may be reduced in length as compared to conventional wastewater treatment screens.

摘要： A wastewater treatment includes an elevated aeration system. The aeration system is used to provide air and nutrients to biological growth in a wastewater treatment vessel, and to promote circulation of the support media used for the biological growth. The aeration system is elevated from the bottom of the reactor vessel by supports that extend from sidewalls of the vessel, or from suspension systems that hang the aeration system at a desired height. Silt, debris and sludge may be removed from the free space between the elevated aeration system and the vessel floor. Mechanical collection or removal devices may be positioned between the elevated aeration system and the reactor floor.
