Mass transfer membrane distillation

WebJan 3, 2024 · Membrane distillation (MD) displays superior characteristics to other technologies to alleviate the ever-increasing freshwater crisis through seawater desalination and/or wastewater recycling. However, the critical challenge in MD is fabricating high-performance membranes. WebThe membrane distillation process is a thermal-driven membrane-based separation process that separates salts and other impurities from a feed solution (e.g., seawater or groundwater) using the partial vapor pressure difference across the membrane.
