Membrane Filtration
StanTech Membrane Filtration:
Process description in principle
Membrane filtration is a process in which synthetic membranes and a hydrostatic pressure difference are used to separate particles and/or macromolecular components that are contained in an aqueous mixture from the solvent. The process so-called microfiltration deals with particles of a size in the range of 0.05 mm to 0.5 mm. The process so-called ultrafiltration is used to treat solutions containing particles/molecular components with sizes down to about 500 Dalton. To separate particles, i.e. molecular components exhibiting seizes below about 500 Dalton, from a solution the process of so-called reverse osmosis has to be performed.
Selected applications:
