“…For dehydration, the dry gas flux was analyzed in References [ 39 , 40 ]. In terms of water recovery from flue gas, the recovered water flux is usually taken as the index, which could be found in References [ 18 , 41 , 42 , 43 , 44 ]. These research studies focus on recovering water to solve the problem of water shortage, such as using recovered water for desulfurization to achieve zero water consumption in desulfurization.…”

Ceramic membrane method for moisture recovery from flue gas of thermal power plants is of considerable interest due to its excellent selection performance and corrosion resistance. However, manufacturing costs of commercial ceramic membranes are still relatively expensive, which promotes the development of new methods for preparing low-cost ceramic membranes. In this study, a method for the preparation of porous ceramic membrane supports is proposed. Low-cost fly ash from power plants is the main material of the membrane supports, and talcum is the additive. The fabrication process of the ceramic membrane supports is described in detail. The properties of the supports were fully characterized, including surface morphology, phase composition, pore diameter distribution, and porosity. The mechanical strength of the supports was measured. The obtained ceramic membrane supports displays a pore size of about 5 μm and porosity of 37.8%. Furthermore, the water recovery performance of the supports under different operating conditions was experimentally studied. The experimental results show that the recovered water flux varies with operating conditions. In the study, the maximum recovered water flux reaches 5.22 kg/(m2·h). The findings provide a guidance for the ceramic membrane supports application of water recovery from flue gas.

“…The pore size of the microporous film is smaller than water droplets but larger than water vapor molecules; therefore, water droplets can hardly permeate while steam easily penetrate. Microporous film exhibits excellent protective performance, but the water vapor transmission (WVT) is limited due to the quite small pore size. − Microporous films such as PTFE are often used as materials for medical protective clothing, but they do not bond well with other materials due to poor surface adhesion. Flash distillation nonwovens exhibit the highest protection level but at the expense of low comfortable property.…”

“…In parallel, air cooling based on membrane air-dehumidification has emerged as an alternative to conventional mechanical vapor-compression cooling, offering benefits in energy savings, environmental sustainability, and economic feasibility [ 11 , 12 , 13 , 14 , 15 ]. This approach involves hydrophilic membranes for isothermal water vapor separation from ambient air, allowing for efficient dehumidification and a comfortable humidity level [ 16 , 17 , 18 ]. Among various options, thin film composite membranes supported on porous UF membranes like PS are excellent candidates due to their flexibility, ease of fabrication, and high water/air selectivity.…”

Ultrafiltration (UF) polymeric membranes are widely used in water treatment and support desalination and gas separation membranes. In this article, we enhance the performance of Polysulfone (PSF) mixed matrix membranes (MMMs) by dispersing different concentrations of thermally reduced graphene (TRG) nanofillers. The UF PSF-TRG MMMs were fabricated via the phase inversion process, and the impact of TRG loading on the characteristics of the membrane, including hydrophilicity, porosity, roughness, and morphology, were analyzed using a contact angle measurement, atomic force microscopy (AFM), scanning electron microscopy (SEM), and dynamic mechanical analysis. Incorporating TRG into the PSF matrix led to favorable effects in the instantaneous de-mixing during phase inversion, increasing the porosity and hydrophilicity of MMMs and improving the mechanical properties of the membranes. Moreover, membrane performance was examined to remove dispersed oil from oil–water emulsion and support air-dehumidification membranes. MMM performance in terms of flux and oil rejection was superior to the control PSF membrane. Incorporating 0.25% TRG into PSF resulted in a 70% water flux increase and higher oil rejection compared to the control PSF membrane. As a support for air-dehumidification membranes, the MMM also demonstrated enhanced humidity reduction and an over 20% increase in water vapor permeance over the control PSF membrane. These results indicate that the PSF-TRG MMMs are an excellent candidate for reliable oil–water separation and as a support for air-dehumidification membranes.
