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:

  • Water treatment, wastewater treatment
  • Sterilization
  • Fractionating, cleaning and concentrating aqueous molecular mixtures
  • Water desalination

Components of specific StanTech interest:

  • Membranes of flat sheet and hollow fiber design for special separation tasks
  • Problem-oriented module systems
