Special Issue Information

Dear Colleagues,

An MBR is an efficient technology for industrial and domestic wastewater treatment, combining a membrane filtration system and activated sludge biological treatment. MBR technology seems to be a good choice as most of the solids including bacteria will be completely eliminated through membrane separation, which enables the final effluent to be directly discharged to the surface water or more easily post-treated for wastewater-reuse applications. Major limitations for the widespread application of membrane bioreactors (MBR) include membrane fouling and energy consumption. Membrane fouling reduces plant productivity, shortens membrane lifetime, and increases energy consumption and the need for chemical cleaning.

This Special Issue on “Advanced Membrane Bioreactors for Wastewater Treatment 2nd Edition” of the journal Membranes seeks contributions to assess the state of the art and future developments in the field of advanced membrane bioreactors. Topics include but are not limited to fouling characterization; new fouling mitigation strategies (quorum quenching, mechanical cleaning processes, etc.); anaerobic MBR; biofilm MBR; new membrane materials for MBR; gravity-driven MBR; hybrid MBR; micro-pollutants issues; and the theory, modeling, design, management, and applications of advanced membrane bioreactors. Authors are invited to submit their latest results; both original papers and reviews are welcome.

A simple model is developed for membrane fouling, taking into account two main fouling phenomena: cake formation, due to attached solids on the membrane surface, and pore clogging, due to retained compounds inside the pores. The model is coupled with a simple anaerobic digestion model for describing the dynamics of an anaerobic membrane bioreactor (AnMBR). In simulations, we investigate its qualitative behavior: it is shown that the model exhibits satisfying properties in terms of a flux decrease due to membrane fouling. Comparing simulation and experimental data, the model is shown to predict quite well the dynamics of an AnMBR. The simulated flux best fits the experimental flux with a correlation coefficient r2=0.968 for the calibration data set and r2=0.938 for the validation data set. General discussions are given on possible control strategies to limit fouling and optimize the flux production. We show in simulations that these strategies allow one to increase the mean production flux to 33 L/(h·m2),whereas without control, it was 18 L/(h·m2). Full article

Membrane fouling caused by complex greywater synthesized by personal care products and detergents commercially available for household applications was investigated using dead-end microfiltration (MF) and analyzed systematically by a multistage Hermia blocking model as a first attempt. The highest flux decline was associated with the smallest pore size of the membrane (0.03 μm). This effectiveness was more pronounced at higher applied pressures to the membrane. A cake layer was formed on the membrane consisting mainly of silica particles present as ingredients in greywater. Although organic rejection was low by the porous MF membrane, the organic compound contributed to membrane fouling in the filtration stage. With a 0.03 μm pore size of the membrane, dominant fouling mechanisms were classified into three stages as applied pressure increased, such as complete pore blocking, intermediate pore blocking, and cake layer formation. Specifically, during the early stage of membrane filtration at 1.5 bar, membrane fouling was determined by complete pore blocking in the 0.10 μm pore size of the membrane. However, the later stage of membrane fouling was controlled mainly by intermediate pore blocking. Regardless of the applied pressure, pore constriction or standard blocking played an important role in the fouling rate with a 0.45 μm pore size of the membrane. Our results also support that complex formation can occur due to the concentration of organic and inorganic species present in simulated greywater. Thus, strategic approaches such as periodic, chemically enhanced backwashing need to be developed and tailored to remove both organic and inorganic fouling from MF membranes treating greywater.
