    摘要: Embodiments described methods, systems and apparatuses to utilize a plurality of membrane cartridges and a housing frame comprising a lightweight corrosion resistant material (e.g., non-corrosive metals, non-corrosive composites such as PVC, HDPE and FRP). The anti-corrosive properties of said frame allow of it to be re-used (e.g., with replaced MBR filters). Said MBR frame may be used in a single function or multi-function wastewater treatment container. Said container may also include a corrosion resistant liner coupled to interior portions of each of the base and side walls of the basin, an inlet to receive wastewater treatment influent into the basin, and an outlet to output wastewater treatment process material from the basin.

    摘要: A media bed reactor may be used to remove selenium from water. An exemplary reactor has a fluid injection system with one or more outlets located within the media bed. The fluid injection system may be connected to a source of gas, liquid or both. In a selenium treatment process, a denitrification zone forms above a selenium-reducing zone in the media bed. Operation of the reactor includes a step of flowing a fluid upwards through only an upper part of the bed. This upper part of the bed preferably contains at least most of the denitrification zone.
