Special Issue Information

Dear Colleagues,

Membrane separation has been widely applied to water/wastewater treatment in recent years due to high product water quality, little or no chemical/additive use and straightforward process handling. However, there are several challenges which limit the successful utilization of traditional membranes: membrane fouling and trade-off effect between permeability and rejection. Recent researchers have focused on developing novel membranes for water treatment, aiming to solve membrane fouling and break through trade-off effect between permeability and rejection. The integration of novel materials including functional polymers, nanofibers, 2D materials into membranes gives a promising solution to increase the membrane performance, such as reduced fouling, enhanced rejection and permeation, etc. The development of these novel membranes are expected to enlarge the application in membrane-based water treatment. We are seeking high-quality research and review papers in the special issue on “Recent Progress in Synthesis and Application of Novel Membranes for Water Treatment” of the journal Membranes. The special issue will specifically cover all aspects associated with the fabrication of novel membranes, their modifications/functionalization, and their applications in membrane-based processes for water treatment. Topics include but are not limited to: recent progress in novel membranes by functional materials, as well as membrane fabrication, novel design principles, theoretical simulations and various applications including desalination, energy storage, and environmental remediation. State-of-the-art and critical reviews are also welcome.

The performance of a Decentralized Wastewater Treatment System (DWTS) comprising an Anaerobic Baffled Reactor (ABR) and an Anaerobic Filter (AF) and Membrane Filtration (MF) module was studied for domestic wastewater treatment. The efficiency of the system was evaluated by running ABR at four different HRTs (14, 12, 10, and 8 h) resulting in COD removal efficiencies of 74, 72, 69, and 65%, respectively. The performance of AF using four different filtration media, i.e., PVC pipe (25 mm), PVC pipe (20 mm), PVC pipe (15 mm), and Kaldnes K3, was determined at optimized HRT (12 h). Among all the filtration media tested, the highest performance efficiency of the system was found with the PVC pipe (20 mm), which showed COD, TP, and TKN removal of 79, 32, and 63%, respectively. The efficacy of the system was proven via significant COD and turbidity removal of 94.6 and 87.2%, respectively, by the combined system. Full article

One of the main trends in the development of solar interface evaporation technology is the simple, efficient, and environmentally friendly bio-based evaporation device. However, the development of bio-based evaporators with high water evaporation rates and good pollution removal capability is a significant challenge. Here, we present a carbonized cattail–agarose hydrogel (CCAH) membrane with numerous microchannels resembling bamboo knots, exceptional hydrophilicity, outstanding light absorption capability, and potent adsorption. Under one solar irradiation, its evaporation rate and efficiency reached 1.93 kg m−2 h−1 and 95.8%, respectively. More importantly, the CCAH membrane produces steam water that is almost totally free of salts (Na+, K+, Mg2+, and Ca2+), heavy metal ions (Pb2+, Cd2+, and Cr2+), and organic dyes (Rhodamine B, methylene blue, and methyl orange). The CCAH membrane is highly promising for the use of saltwater desalination and wastewater recovery to help people in impoverished areas with water scarcity problems. Full article
