摘要： An apparatus and method for selecting, retaining or bioaugmenting solids in an activated sludge process for improving wastewater treatment using a screen device. If desired, the screen device may include a drum, and the rotating speed of the drum may be used to control the solids retained. Effluent including waste biomass may exit the screen device. No other discharge unit from the screen device may be required.

摘要： An apparatus and a method for removing constituents from an influent. The apparatus includes a biological processor that receives a water mixture as influent and outputs a liquor, a solid-liquid separator that receives the liquor and separates the liquor into a liquid and a solid; and a biofilm media that includes at least one media surface. The biofilm media may have a biofilm mass, biofilm volume, biofilm density, biofilm thickness, hydraulic retention time or solids residence time. The at least one media surface grows a biofilm that removes one or more constituents contained in the influent. The biofilm mass, biofilm volume, biofilm density, biofilm thickness, hydraulic retention time or solids residence time can be controlled by at least one of a physical process, a biological process or a chemical process.
