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 seize 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
seizes 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:
• Water-treatment, Wastewater-treatment
• Sterilization
• Fractionating, cleaning and concentrating aqueous molecular mixtures
• Waterdesalination
