Membrane filtration is used to remove particles that are too fine for ordinary filtration techniques. It can also be used for concentrating, fractionating, purifying and regenerating liquids, replacing traditional methods of separation by evaporation and centrifugation. For more information, see Section 4.1 of the page New Energy Efficient Technologies That Are Applicable to Manufacturing Processes on the Natural Resources Canada Web site.
