    摘要： Described are a method and apparatus for the biological treatment of wastewater in an activated sludge process that use a primary separator to produce a pretreated wastewater, a pressurized aeration tank which has a headspace pressure of between about 1 and about 10 psi, and a secondary separator to separate mixed liquor from the aeration tank into an activated sludge component and a clarified liquor component. The aeration tank has a rectangular or square base and may be cuboid. Embodiments contemplate making a package plant, and may use a screening tank, a membrane separator, air eductors to aerate a return activated sludge, and multiplier nozzles to introduce the return activated sludge into the aeration tank. The apparatus has a small footprint, is simple in design, and is low maintenance.

    摘要： Telescopic containers (10, 100) for containing fluids associated with hydrocarbon production are disclosed. Such containers (10, 100) may comprise a lower container section (12), an upper container section (14) moveable between a retracted position and an extended position in a telescopic manner relative to the lower container section (12) and a sealing member (40, 50). The sealing member (40, 50) prevents or substantially prevents leakage of fluid from the container (10, 100) between the upper container section (14) and the lower container section (12). The lower container section (12) may define an elongated and/or multi-sided shape.
