A practitioner’s perspective on the application and research needs of membrane bioreactors for municipal wastewater treatment
چکیده انگلیسی

The application of membrane bioreactors (MBRs) for municipal wastewater treatment has increased dramatically over the last decade. From a practitioner’s perspective, design practice has evolved over five “generations” in the areas of biological process optimization, separating process design from equipment supply, and reliability/redundancy thereby facilitating “large” MBRs (e.g. 150,000 m3/day). MBR advantages and disadvantages, and process design to accommodate biological nutrient removal, high mixed liquor suspended solids concentrations, operation and maintenance, peak flows, and procurement are reviewed from the design practitioner’s perspective. Finally, four knowledge areas are identified as important to practitioners meriting further research and development: (i) membrane design and performance such as improving peak flow characteristics and decreasing operating costs; (ii) process design and performance such as managing the fluid properties of the biological solids, disinfection, and microcontaminant removal; (iii) facility design such as equipment standardization and decreasing mechanical complexity; and (iv) sustainability such as anaerobic MBRs.
