Applications

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

Frequently Asked Questions

Flow characteristics for a spiral element and flat sheet membrane are significantly different and are really only comparable on a qualitative basis. Variability in the membrane manufacturing process, differences in water composition, test procedures, and test equipment, used in a factory, laboratory, or elsewhere, will impact water flux results.
