Abstract:

The concept of membrane bioreactor systems consists of – “Utilizing a bioreactor and microfiltration or ultra-filtration as one unit process for waste water treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration.” Early MBRs were based on pressurized modules in recirculation loops, but the current state of the art involves immersing the membranes in the activated sludge and drawing the treated water by suction. The idea of coupling activated sludge with membrane separation was conceived in the mid-1960s at Dorr-Oliver (Stanford, Connecticut), but the technology was not commercialized in North America. Thetford Systems (Ann Arbor, Michigan), which later became part of ZENON, accomplished this in the early 1970s. The company developed a membrane bioreactor system for on-site treatment and recycling of wastewater. The system, called Cycle Let was based on an aerobic – anoxic activated sludge process with tubular ultra-filtration (UF) in a two-pump feed and bleed loop. Permeate from the UF membranes was disinfected in a UV unit, and reused for toilet flushing.
