Abstract
Described herein is aerobic granular sludge gravity-driven membrane system, methods of making and using thereof are described. The aerobic granular sludge (AGS) integrated with a gravity-driven membrane (GDM) filtration system is an energy efficient wastewater treatment system that takes advantage of AGS reactor systems integrated with gravity-driven membrane system to reduce membrane fouling and produce microbiologically and chemically safe water. The AGS-GDM system includes at least an AGS reactor tank containing raw wastewater and granular sludge and a membrane tank including one or more gravity-driven membrane(s).
Claims16
A wastewater treatment system comprising an aerobic granular sludge (AGS) tank coupled to a gravity-driven membrane (GDM) tank comprising one or more gravity-driven membrane(s), wherein the one or more gravity-driven membrane(s) forms a membrane unit that is attached to the bottom or near the bottom of the GDM tank, and
- wherein the AGS tank and the GDM tank are integrated in a single vessel and divided by a barrier, and the AGS tank and the GDM tank are configured such that when in use, an effluent overflows unidirectionally from the AGS tank into the GDM tank via the top of the GDM tank, wherein effluent cannot flow from the GDM tank into the AGS tank.
