Membrane separation is a technique that uses a semi-permeable barrier to selectively separate specific components from a fluid mixture. Unlike traditional separation methods such as distillation or evaporation, membrane processes do not require thermal energy to effect a phase change. Instead, they rely on physical properties like molecular size, charge, or diffusivity, making them highly energy-efficient and sustainable alternatives for modern industrial engineering.
Uses a high-concentration "draw solution" to naturally pull water across a membrane without external hydraulic pressure. 3. Electrically-Driven Processes
Concentration of macromolecules and proteins.
