Special Issue Information

Dear Colleagues,

Membrane bioreactors (MBRs) constitute a highly advanced technology for efficient municipal and industrial wastewater treatment all over the world, for wastewater treatment and reuse. In recent decades, outstanding progress has been achieved in the research and development of advanced MBRs, including new materials and hybrid processes. Among the cutting-edge technologies are highly efficient strains applied into MBRs for the enhancement of biological activity and fouling reduction, MBRs combined with microalgae growth, design and fabrication of novel anti-fouling composited membranes, hybrid MBRs combined with novel dynamic membranes or with other technologies such as advanced oxidation processes and high-retention membranes, and improved MBRs with the addition of hydrophilic and recalcitrant compounds for micropollutant removal. Other innovative MBR configurations that may additionally remove pharmaceutically active compounds are the use of improved MBR with activated carbon adsorption or with carrier media for enhanced biofilm growth. Moreover, advanced processes including the integration of anaerobic treatment processes and membrane bioreactors with microbial fuel cells may have a highly positive synergetic effect on energy recovery, power output, as well as treatment efficiency.

The aim of the Special Issue on "Cutting Edge Technologies in Membrane Applications to Improve Wastewater Treatment Performance" of the journal Membranes is to seek state-of-the-art contributions outlining the latest research dealing with advanced and hybrid MBR designs, processes, and applications. Authors are also encouraged to submit initial research works or review papers.

This study explored the use of a combination of hydrothermal and sol–gel methods to produce porous titanium dioxide (PTi) powder with a high specific surface area of 112.84 m2/g. The PTi powder was utilized as a filler in the fabrication of ultrafiltration nanocomposite membranes using polysulfone (PSf) as the polymer. The synthesized nanoparticles and membranes were analyzed using various techniques, including BET, TEM, XRD, AFM, FESEM, FTIR, and contact angle measurements. The membrane’s performance and antifouling properties were also assessed using bovine serum albumin (BSA) as a simulated wastewater feed solution. Furthermore, the ultrafiltration membranes were tested in the forward osmosis (FO) system using a 0.6-weight-percent solution of poly (sodium 4-styrene sulfonate) as the osmosis solution to evaluate the osmosis membrane bioreactor (OsMBR) process. The results revealed that the incorporation of PTi nanoparticles into the polymer matrix enhanced the hydrophilicity and surface energy of the membrane, resulting in better performance. The optimized membrane containing 1% PTi displayed a water flux of 31.5 L/m2h, compared to the neat membrane water value of 13.7 L/m2h. The membrane also demonstrated excellent antifouling properties, with a flux recovery of 96%. These results highlight the potential of the PTi-infused membrane as a simulated osmosis membrane bioreactor (OsMBR) for wastewater treatment applications. Full article

The increase in industry and population, together with the need for wastewater reuse, makes it necessary to implement new technologies in the circular economy framework. The aim of this research was to evaluate the quality of the effluent of an algae membrane photobioreactor for the treatment of the effluent of an urban wastewater treatment plant, to characterise the ultrafiltration membranes, to study the effectiveness of a proposed cleaning protocol, and to analyse the performance of the photobioreactor. The photobioreactor operated under two days of hydraulic retention times feed with the effluent from the Los Vados wastewater treatment plant (WWTP) (Granada, Spain). The microalgae community in the photobioreactor grew according to the pseudo-second-order model. The effluent obtained could be reused for different uses of diverse quality with the removal of total nitrogen and phosphorus of 56.3% and 64.27%, respectively. The fouling of the polyvinylidene difluoride ultrafiltration membrane after 80 days of operation was slight, increasing the total membrane resistance by approximately 22%. Moreover, the higher temperature of the medium was, the lower intrinsic resistance of the membrane. A total of 100% recovery of the membrane was obtained in the two-phase cleaning protocol, with 42% and 58%, respectively. Full article
