  • Coating commercially available polyether sulfone (PES) membranes used in membrane bioreactors produces a four fold increase in membrane operation times.
  • With a fixed flux of 20l/m2.hr uncoated membranes reached a transmembrane pressure of 0.5bar after 27 hours. The G2O coated membranes required 105 hours to reach the same transmembrane pressure.
