Special Issue Information

Dear Colleagues,

Membranes have important environmental applications ranging from water treatment to wastewater treatment and reuse, desalination, air filtration, etc. Various membrane-based processes have been involved, including reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), membrane bioreactor (MBR), membrane distillation (MD), forward osmosis (FO), membrane contactor, etc. These processes have been widely used for pollution control, resource recovery, and energy generation. They play a key role in the removal of pathogens, heavy metals, micropollutants, and other harmful contaminants. New membrane materials and structures have been developed to greatly enhance their permeability, selectivity, and stability in these applications.

This Special Issue on “Membranes for Environmental Applications 2020” of Membranes highlights the latest developments and future perspectives of various membrane-based environmental applications. Both reviews and original articles are welcome.

Performance Improvement and Biofouling Mitigation in Osmotic Microbial Fuel Cells via In Situ Formation of Silver Nanoparticles on Forward Osmosis Membrane

An osmotic microbial fuel cell (OsMFC) using a forward osmosis (FO) membrane to replace the proton exchange membrane in a typical MFC achieves superior electricity production and better effluent water quality during municipal wastewater treatment. However, inevitable FO membrane fouling, especially biofouling, has a significantly adverse impact on water flux and thus hinders the stable operation of the OsMFC. Here, we proposed a method for biofouling mitigation of the FO membrane and further improvement in current generation of the OsMFC by applying a silver nanoparticle (AgNP) modified FO membrane. The characteristic tests revealed that the AgNP modified thin film composite (TFC) polyamide FO membrane showed advanced hydrophilicity, more negative zeta potential and better antibacterial property. The biofouling of the FO membrane in OsMFC was effectively alleviated by using the AgNP modified membrane. This phenomenon could be attributed to the changes of TFC–FO membrane properties and the antibacterial property of AgNPs on the membrane surface. An increased hydrophilicity and a more negative zeta potential of the modified membrane enhanced the repulsion between foulants and membrane surface. In addition, AgNPs directly disturbed the functions of microorganisms deposited on the membrane surface. Owing to the biofouling mitigation of the AgNP modified membrane, the water flux and electricity generation of OsMFC were correspondingly improved. Full article
