Summary: In this study, a simple and highly effective method to enhance the water vapor flux in vacuum membrane distillation (VMD) was proposed and demonstrated by introducing a gas flow on the vacuum side. Experimental and modelling results confirmed that gas flow can effectively enhance mass transfer in VMD by minimizing the boundary layer effect. A higher gas flow velocity results in a much higher water vapor flux due to reduced boundary layer effect and temperature polarization. The study provides a cost-effective method to enhance the water vapor flux in VMD and contributes to understanding vapor condensation and mass transfer mechanisms in thermally-driven membrane processes.

Summary: The engineering of electrocatalytic membrane reactors integrates membrane separation with electrocatalytic technology for efficient removal of emerging organic pollutants from waste-water. Electro-responsive microfiltration carbon nanofibre (CNF) membranes were synthesized by electrospinning and subsequent carbonization, followed by oxygen plasma treatment to enhance their wettability and reactivity for electrocatalytic water treatment. The CNF membranes exhibited fine-tuned electrocatalytic performance and improved water permeance, resulting in significantly higher removal efficiency of methylene blue (MB) and acetaminophen (ACP) during combined microfiltration and electrocatalytic reaction compared to microfiltration alone. The success of this study lies in the enhanced wettability and raised electro-oxidation capacity of the oxygen plasma treated CNF membranes.
