Abstract: The inventions add a modified phase separator in the main line of a wastewater treatment process for enhanced BOD and nutrient removal with a membrane system. In addition, treatment methods and systems are described for high flux membrane filtration to meet secondary and tertiary treatment standards. Phase separation and membrane filtration techniques are employed to create concentrated return solids that are recycled in low flow volumes to reduce equipment sizing, reduce the physical space required for treatment and save energy costs without reducing treatment performance.

Abstract: The inventions describe a phased activated sludge treatment system that incorporates elements of batch treatment technology into a flow-through treatment process. Control of mixing and aeration systems are independent to facilitate the operation of the main reactor vessel in alternating aerated and anoxic conditions. Conditioning vessels in communication with the main reactor are employed to preferentially control the distribution and balance of nitrogen and phosphorus compounds in the reactor and to remove such biological nutrients concurrently with BOD and TSS in the wastewater. The inventions provide the beneficial results of providing greater operator control of flow-through treatment processes, power saving and reduced operation and maintenance costs in comparison to conventional flow-through treatment technologies.
