Organic membranes are the most widely used membranes in industrial processes due to their high-packing density, small footprints, and lightweight characters. Among the organic membranes, porous poly(tetrafluoroethylene) (PTFE) membrane exhibits outstanding chemical stability, high heat resistance, strong hydrophobicity, and high fracture toughness  due to the strong C-C and C-F bonds and the carbon backbone, which is protected by the uniform helical sheath formed by the electron cloud of the fluorine atoms. These properties make it suitable for a variety of applications, such as exhaust-gas treatment, membrane distillation (MD), osmotic distillation (OD), and oil-water separation.The requirement for specific membrane properties varies with its targeted application. PTFE membranes were...

Persistent drivers of water stress, such as climate change and urban population growth, are motivating interest in potable reuse systems. For extreme environments (e.g., in space) or in locations with extenuating circumstances (e.g., military forward operating bases), water treatment systems that are compact and easily deployable are required. Furthermore, at forward operating bases, significant risk is associated with convoys supplying potable water and fuel to the base as well as convoys taking wastewater away; thus, a system that can reclaim wastewater for potable reuse with a low electrical energy requirement is of critical importance. The development of potable reuse systems tailored to meet these unique challenges has direct implications for development of municipal potable reuse sys...

Membrane separation technology is widely explored for various applications, such as water desalination and wastewater treatment, which can alleviate the global issue of fresh water scarcity. Specifically, carbon nanotubes (CNTs)-based composite membranes are increasingly of interest due to the combined merits of CNTs and membrane separation, offering enhanced membrane properties.Clean water is an essential resource for human life and our ecosystem. However, due to the increasing growth of population and rapid development of economy and urbanization, the increasing pressure on water scarcity issue highly requires cost-effective water treatment technologies to produce high-quality clean water. On the one hand, seawater and brackish water desalination technologies seem to be the most fundamen...

Recently, an increasing level of attention has focused on the emerging technology of anaerobic dynamic membrane bioreactors (AnDMBRs), owing to its merits such as low membrane module cost, easy control of membrane fouling, low energy consumption and sludge production, as well as biogas production.As such, the combination of an anaerobic treatment process and membrane filtration technology, the so-called anaerobic membrane bioreactor (AnMBR), has been successfully applied at various scales to maintain anaerobic microorganisms. Hydraulic retention time (HRT) and solids retention time (SRT) in AnMBRs can be independently controlled to extend process applicability for treating wastewaters of various strengths from industries  and municipalities  , as well as solid wastes (such as foo...
