“…The same observation was confirmed by a theoretical investigation by Sethunga et al, and they further revealed that the maximum outlet gas purity can be obtained with a lower G/L ratio reached by adjusting L rather than G [43]. Apart from the G/L ratio, it was found that the membrane inner diameter, which can change the linear velocity at a fixed G/L ratio, gives a direct impact on the CH4 transport when the liquid is fed to the lumen side [46]. When the membrane inner diameter becomes smaller, the D-CH4 recovery flux can be increased due to an increase of liquid velocity.…”

Increasing demand for water and energy has emphasized the significance of energy-efficient anaerobic wastewater treatment; however, anaerobic effluents still containing a large portion of the total CH4 production are discharged to the environment without being utilized as a valuable energy source. Recently, gas–liquid membrane contactors have been considered as a promising technology to recover such dissolved methane from the effluent due to their attractive characteristics such as high specific mass transfer area, no flooding at high flow rates, and low energy requirement. Nevertheless, the development and further application of membrane contactors were still not fulfilled due to their inherent issues such as membrane wetting and fouling, which lower the CH4 recovery efficiency and thus net energy production. In this perspective, the topics in membrane contactors for dissolved CH4 recovery are discussed in the following order: (1) operational principle, (2) potential as waste-to-energy conversion system, and (3) technical challenges and recent efforts to address them. Then, future efforts that should be devoted to advancing gas–liquid membrane contactors are suggested as concluding remarks.

“…Sethunga, Lee, Lee, Wang, and Bae (2019) studied the impacts of membrane physicochemical properties on the efficiency of dissolved CH 4 removal from anaerobic effluents. They postulated that increasing the mass transfer area decreases CH 4 flux, while a larger liquid flow rate results in an overall reduction in CH 4 recovery.…”

“…Membrane-based technologies used for water treatment can be an excellent alternative to handle wastewater including both conventional and emerging pollutants as they can provide technological (e.g., high quality of treated water) and economic (e.g., small footprint and low unit cost of production) advantages over other water treatment processes [ 8 , 9 , 10 ]. However, they still need to be further improved to ensure the relative price competitiveness and practical feasibility for highly efficient wastewater treatment, given that wastewater treatment is likely to require a much lower cost of treatment as compared to the production of drinking water.…”

Various pollutants of different sizes are directly (e.g., water-borne diseases) and indirectly (e.g., accumulation via trophic transfer) threatening our water health and safety. To cope with this matter, multifaceted approaches are required for advanced wastewater treatment more efficiently. Wastewater treatment using mixed matrix membranes (MMMs) could provide an excellent alternative since it could play two roles in pollutant removal by covering adsorption and size exclusion of water contaminants simultaneously. This paper provides an overview of the research progresses and trends on the emerging materials used to prepare MMMs for pollutant removal from water in the recent five years. The transition of the research trend was investigated, and the most preferred materials to prepare MMMs were weighed up based on the research trend. Various application examples where each emerging material was used have been introduced along with specific mechanisms underlying how the better performance was realized. Lastly, the perspective section addresses how to further improve the removal efficiency of pollutants in an aqueous phase, where we could find a niche to spot new materials to develop environmentally friendly MMMs, and where we could further apply MMMs.
