网页How Membrane Filtration Works. The basic technology behind membrane filtration involves using a semi-permeable membrane to separate a liquid into two distinct streams. Pumping this liquid across the surface of the membrane creates a positive trans-membrane pressure that forces any components smaller than the porosity of the membrane to pass
