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.
