Web30 mrt. 2024 · The membrane is the heart of MD technology. Membrane hydrophobicity is a crucial characteristic for highly efficient MD membranes, as only water vapor is allowed to penetrate from one side (hot stream) to the other (cold stream). Typically, hydrophobic surfaces have contact angles larger than 90 °C according to the Young equation [ 16 ]. WebThe low throughput of the disperse phase is one of the issues in cross-flow membrane emulsification.
