“…Membrane bioreactor (MBR) is becoming an established technology in treatment of municipal wastewater, with a number of installations in the biological nutrient removal exceeding capacity of 50 ML/d (Canham 2009). Initially the membrane module was utilized outside the reactor in an external configuration.…”

“…This configuration, called a submerged membrane bioreactor (SMBR) was used to lower the energy costs in smaller installations (Ueda et al, 1997;Yamamoto et al, 1989). Today, most full scale larger MBR are conventionally designed as a system of a separate bioreactor tank with mixed liquor flowing to separate tank housing the submerged membranes (Canham 2009).…”

The occurrence of membrane fouling is still the major factor hindering the widespread use of membrane bioreactor (MBR) technology. Furthermore, enhanced biological phosphorous removal would be limited in MBRs applications. The main objective of this study was to develop the Submerged Membrane Electro-Bioreactor (SMEBR), for decreasing the fouling rate and increasing the performance in term of phosphorus removal. Combining biological, membrane and electrochemical processes in one operation SMEBR unit has achieved 52 % reduction in membrane fouling and more than 98% efficiency of PO 4-P removal.

Operating results from two full-scale membrane bioreactors (MBRs) practicing biological and chemical phosphorus and biological nitrogen removal to meet stringent effluent nutrient limits are analyzed. Full-scale results and special studies conducted at these facilities resulted in the development of guidelines for the design of MBRs to achieve stringent effluent nutrient concentrations-as low as 0.05 mg/L total phosphorus and 3 mg/L total nitrogen. These guidelines include the following: (1) direct the membrane recirculation flow to the aerobic zone, (2) provide intense mixing at the inlets of the anaerobic and anoxic zones, (3) maintain internal recirculation flowrates to maintain the desired mixed liquor suspended solids distribution, and (4) carefully control supplemental metal salt addition in proportion to the phosphorus remaining after biological removal is complete. Staging the various process zones and providing effective dissolved oxygen control also enhances nutrient removal performance. The results demonstrated that process performance can be characterized by the International Water Association (London, United Kingdom) (IWA) activated sludge model number 2d (ASM2d) and the Water Environment Federation (Alexandria, Virginia) chemical phosphorus removal model. These models subsequently were used to develop unique process configurations that are currently under design and/ or construction for several full-scale nutrient removal MBRs. Water Environ.
