SYSTEM, METHOD AND APPARATUS FOR WATER TREATMENT USING A PHYSICAL SEPARATOR |
| 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. |

1. An apparatus for selecting and retaining particles, the apparatus comprising:
a physical device such as a classifying screen applying a mesh-size in the 10-5,000 micron range to select particles from an influent, wherein the influent is at least one of a wastewater influent, an effluent from a solids-liquid separator, or a mixed liquor from a tank; and wherein the apparatus is configured to return at least some of the selected particles to an upstream portion. |
