WC&P is proud to offer this comprehensive glossary to our readers and website visitors. This living document is intended to serve as an easy-to-use reference source for information on the POU/POE water treatment industry.
Any suggestions or input that would further enhance or expand the glossary are strongly encouraged.
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.
Flow of solution tangentially or parallel to the surface of the membrane. This contrasts with dead-end flow, in which the liquid flows perpendicular to the surface of the filter. In crossflow, only a fraction of the crossflow solution passes through the membrane. Reverse osmosis is an example of crossflow filtration: separation of the components of water is accomplished by a semi-permeable membrane through the application of press and tangential flow, which also minimizes particle build-up. Ultrafiltration, nanofiltration and microfiltration are crossflow filtration processes.
