 Water Pollution and Contro l: Membrane Separation: Membrane separation is a process that uses thin, semi-permeable membranes to separate molecules based on their size, charge, and other characteristics.  Working ·               Membranes are made from materials like polymers, ceramics, and metals.  ·          The pressure difference across the membrane determines which substances can pass through.  ·          The process can be used to separate dissolved solutes from water.           Membrane separation uses a pressure difference across a membrane to separate molecules. The type of membrane separation process depends on the size of the molecules being separated, the desired separation efficiency, and other factors.  1.       High pressure is appl...
