Abstract
Three dimensional fabric media of the present invention are used with moving bed biofilm reactors, and are generally constructed of an open weave substrate that allows the diffusion of gas, nutrients and food, while protecting and serving as an attachment site for a variety of microbial colonies in both anoxic and aerobic zones. The media is preferably constructed of high-density polyester fiber and has a specific gravity of approximately 0.96.
Claims6
A Moving Bed Biofilm Reactor system including:
- A. A body of water;
- and
- B. A plurality of woven media members each consisting essentially of two outer surfaces being less than three millimeters in thickness, having a specific gravity between 0.94 and 0.98, having a length between 25 to 75 millimeters, having a width between 25 to 75 millimeters, and connected with a multitude of interconnecting fibers in an open weave pattern, wherein said multitude of interconnecting fibers being curved and joining said two outer surfaces whereby said plurality of woven media members and said multitude of interconnecting fibers are spaced to define a plurality of recesses developing a sustained gradient of oxygen concentration within said media members, and wherein said woven media members having a surface area consisting essentially of approximately 1,000 to approximately 2,000 square meters per cubic meter and thereby adapted to provide a high surface area per unit volume to accommodate an amount of biofilm and withstand a mechanical force within said Moving Bed Biofilm Reactor system consisting essentially of impact with at least one mixer blade.
