摘要： A process and system for treating wastewater is described. The invention degrades sludge produced by treatment of the wastewater to reduce or eliminate the need for sludge dewatering and disposal. The invention also reduces the amount of nutrient additives required to sustain the aerobic wastewater treatment process. In one embodiment the invention includes the steps of (a) providing an aerobic treatment system receiving a supply of the wastewater; (b) treating a supply of the sludge to rupture microbial cells present therein to produce treated sludge having an increased liquid:solid ratio and an increased degradation potential in comparison to untreated sludge; (c) conveying a supply of the treated sludge to the aerobic treatment system; and (d) substantially degrading the supply of treated sludge in the aerobic treatment system. The treated sludge may optionally be subjected to anaerobic digestion prior to delivery to the aerobic treatment system.

摘要： A wastewater treatment plant that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor to a hydrodynamic separator (HDS) system, where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system via a first output to a clarifier, and the high concentration wastewater stream is passed via a second output back to the bioreactor. The clarifier performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.

摘要： The invention provides a system for treatment of wastewater. A pumping system pumps wastewater from a source basin to a recipient basin, while a conduit allows gravitational flow of water from a source basin to a recipient basin when the pumping system is inactive. A controller activates the pumping system to pump wastewater from the source basin to a recipient basin when a wastewater level in the source basin is at a first predetermined height or when a rate of gravitational flow wastewater from the source basin to the recipient basin is below a first predetermined flow rate. The controller also turns off the pumping system when the water level in the source basin is at a source basin minimal level and the water level in the recipient basin is at a recipient basin maximal level. The invention also provides a method for operating a wastewater treatment of the invention, and a pumping system for use in the system of the invention.
