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 Automatic control operation is possible Better control of biological activity Quality Effluent that is free of bacteria and pathogens Smaller plant size Higher organic loading rates | Wastewater and Effluent Treatment A Review of Membrane Bio-Reactor Technology PLUS-POINTS of MBR 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 Automatic control operation is possible Better control of biological activity Quality Effluent that is free of bacteria and pathogens Smaller plant size Higher organic loading rates Hydro One 1 MEMBRANE BIOREACTOR MBR FOR ADVANCED WASTEWATER TREATMENT Why MEMBRANE Technology M embrane technology has advanced significantly in the past decade for both water purification and wastewater treatment. Today membrane-based systems have become the preferred technology for many potable water purification applications Cryptosporidium and Giardia control color or suspended solids removal etc. Most recently the combination of membranes with the activated sludge process has redefined basic sewage treatment optimizing the biological treatment operation and yielding a treated effluent that is ideal for reuse. Two key advances in membrane technology are at the leading edge of this trend a. Quality bacteria-free effluent with high efficiency in removing organic inorganic matters b. Minimum plant size with elimination of conventional element c. Stable efficient biological process is maintained Membranes are low-pressure driven element and available in a diverse range of forms and configurations with membrane pore size or molecular weight MW separation being the primary characteristic of differentiation. What is MBR MBR Membrane Brio-Reactor can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. They have proven effective in removing both organic and inorganic contaminants as well as biological entities from wastewater. MBR systems may be used with aerobic or anaerobic suspended growth bioreactors to separate treated wastewater from the .
