  • Reverse Osmosis (RO) Process Water Treatment

    2008-11-1 · Reverse osmosis (RO) has been shown to be a viable technology for water and wastewater treatment. It is a pressure-driven process in which the membrane acts as a semi-permeable barrier that rejects pollutants into a concentrated stream and allows the passage of a largely pure water stream to form what is called the permeate.
