MBR (Membrane Brio-Reactor) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. Set up of MBR plant is mainly utilizing a bioreactor and membrane filtration as one unit process for wastewater treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration, resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration | Hydro One SYSTEM DESIGN OPERATION MANUAL Membrane Bioreactor MBR System Membrane Bioreacotr Operation Maintenance Guideline Hydro One k MBR Introduction MBR Membrane Brio-Reactor can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. Set up of MBR plant is mainly utilizing a bioreactor and membrane filtration as one unit process for wastewater treatment thereby replacing and in some cases supplementing the solids separation function of secondary clarification and effluent filtration resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration. In summary the MBR system is the combination of traditional Actitived Sludge Treatment with the membrane technology. The design criteria of the system shall be base according to the traditional way of Activated Sludge Treatment principle. However on top of that the MBR modules are immersed and located in the air blow tank aeration basin biological reactor tank the clear water is pumped sucked out from the MBR modules. This shall possibly eliminate the needs of secondary clarifier. Advantages of the MBR Better control of biological activity Effluent that is free of bacteria and pathogens Smaller plant size Biodegradation efficiency enhanced 10 30 Short Hydraulic Residence Time HRT Long Sludge Residence Time SRT Activated sludge increase by 2 3 times No secondary settling and disinfecting tank required Higher organic loading rates Typical Applications Living wastewater treatment medical water treatment and reuse residential area hotel etc. Food industry wastewater bean factory cake factory etc. Beverage industry wastewater Agricultural waster Waster water of pharmaceutical Zoology toilet Working principle 3 pcs. of membrane modules are connected parallely through the header of the module to form a cassette frame . It is then connected the suction side of a permeate pump the membranes are subjected to a slight negative .
