  • What is reverse osmosis in water treatment & desalination?
  • 1. Introduction Reverse osmosis (RO) is gaining worldwide acceptance in both water treatment and desalination applications. It is a pressure-driven process whereby a semi-permeable membrane rejects dissolved constituents present in the feed water.
  • Why is organic fouling a major issue in Ro treatment?
  • Organic fouling is a major issue in RO treatment of wastewater effluent due to the high organics content (10–20 ppm) compared to surface waters (2–5 ppm) . Colloidal fouling can be effectively controlled through an ultrafiltration or microfiltration step.
  • How can RO membranes reduce the cost of desalination?
  • Moreover, innovative RO membranes have been designed to treat the highly concentrated brine of a conventional RO system, recovering 60% of that brine as potable water with a TDS of < 200 ppm and reducing the overall cost of desalination by 15–20% and the plant size by 30% . 8.
