Activated sludge process and system |
| abstract |
An activated sludge sewage treatment process and system: the process and system include an enclosed aeration chamber providing a vessel for a mixed liquor formed from a liquid biologically degradable waste and recirculated sludge, with an upper region in the enclosed chamber into which droplets of the mixed liquor are generated and a gas containing a major portion of oxygen is injected under pressure. The gas in the upper region is maintained under pressure and oxygen is transferred to the droplets and mixed liquor at an improved rate. |
