This presentation discusses a hybrid membrane bioreactor which does not use an immersion tank. Flow is inside out. Equipment detail is provided, together with two examples of real world applications. Wastewater quality, and effluent quality data are provided....

The MA DEP has stringent discharge limits on wastewater total organic carbon (TOC) concentration which is dictated by the ground water travel time from discharge point to the public water supply source. The use of a membrane bioreactor (MBR) and RO membranes in tandem is used by the City of Wayland to meet these requirements. The RO system achiev...
