We would like to formally thank and credit such organizations as WQA, AWWA, WEF, Lenntech and other web glossary sources for providing some of the basis and background of this compendium.

Membrane

A thin barrier that allows some compounds or liquids to pass through, and troubles others. It is a semi-permeable skin of which the pass-through is determined by size or special nature of the particles. Membranes are commonly used to separate substances. The term membrane generally refers, not only to the barrier layer described above that is technically the membrane, but also to the entire engineered membrane separation device, including the micro-porous support, the non-woven support material, the carriers, product tube, anti-telescoping device, and the construction of the element. The most commonly used membrane element type is a spiral wound membrane element.
