Forward Osmosis Cells

Forward Osmosis Cells

Sterlitech Forward Osmosis (FO) bench systems operate like traditional reverse osmosis membrane test cells but require less energy and lower pressure to function, which means better fouling resistance. FO cells are most frequently used for desalination and water and wastewater treatment in a variety of industrial processes. Click on the applications tab for more information on where FO cells are used.

Our FO cells are available in modified versions of the CF042 (Delrin Acetal, PTFE, Stainless Steel, or Acrylic) and the Sepa CF systems. The top and bottom of the FO cells feature the same ports (1/4” NPT) for easy connectivity as part of a bench system.

Forward Osmosis technology is most commonly used for an array of wastewater recycling and water reclamation applications. Areas in which an FO cell may be used include:

  • Water reclamation from oil and gas exploration
  • Landfill wastewater
  • Alternative energy/biogas wastewater
  • Medical/dental wastewater
  • Membrane bioreactors
  • Seawater desalination
  • Radioactive wastewater
  • Carpet manufacturing wastewater
  • Pressure Retarded Osmosis (PRO) to generate electricity


Other uses for Forward Osmosis Cells:

  • Pretreatment for Reverse Osmosis procedure
  • Concentrating juices (grape juice to wine, tomato paste)
  • Pharmaceuticals
  • Nutraceuticals
