Special Issue Information

Dear Colleagues,

Membrane bioreactor (MBR) has been well accepted and adopted for wastewater treatment and reuse over the last few decades.  Notwithstansing its advantages, R&D to resolve challenges such as alleviating membrane fouling and reduction in energy consumption has continued to be pursued by academic and the industry by improving the design of MBR system, optimzing the operation of MBR, developing better membranes, etc. To achieve energy and nutrients recovery, anaerobic membrane bioreactor for both domestic and industrial wastewater has received much attention lately. In additon, researchers have also explored novel alternative MBR design and fouling control such as forward osmosis MBR, membrane distillation bioreactor, membrane aeration bioreactor, quarum queching, etc.

This Special Issue on “Design and Development of Membrane Bioreactors” of the journal Membranes seeks contributions to assess the state-of-the-art and future developments of membrane bioreactor. Topics include, but are not limited to, fouling control, process control and optimization, energy reduction, new membrane material, membrane modification, module and reactor design, novel applications, novel alternative MBR, membrane aeration, anaerobic MBR, energy and nutrient recovery, demonstration efforts and industrial exploitation. Authors are invited to submit their latest results; both original papers and reviews are welcome.

A novel membrane bioreactor system utilizes Multi-Walled Carbon Nanotubes (MWCNTs) coated polyurethane sponge (PUs), an electrical field, and a nanocomposite membrane has been successfully designed to diminish membrane with fouling caused by activated sludge. The classical phase inversion was harnessed to prepare Zinc Oxide/Polyphenylsulfone (ZnO/PPSU) nanocomposite membranes using 1.5 g of ZnO nanoparticles (NPs). The prepared nanocomposite membrane surface was fully characterized by a series of experimental tools, e.g., Scanning electron microscope (SEM), Atomic force microscopy (AFM), contact angle (CA), pore size, and pore size distribution. The testing procedure was performed through an Activated Sludge-Membrane Bioreactor (ASMBR) as a reference and results were compared with those obtained with nanotubes coated sponge–MBR (NSMBR) and nanotubes coated sponge-MBR in the presence of an electrical field (ENSMBR) system. Observed fouling reduction of the membrane has improved significantly and, thus, the overall long-term was increased by 190% compared with the control ASMBR configuration. The experimental results showcased that sponge-carbon nanotubes (CNTs) were capable of adsorbing activated sludge and other contaminants to minimize the membrane fouling. At a dosage of 0.3 mg/mL CNT and 2 mg/mL of SDBS, the sponge-CNT was capable of eliminating nitrogen and phosphorus by 81% and >90%, respectively. Full article
