Current Cellulose Acetate (CA) membranes used in Reverse Osmosis (RO) desalination plants have poorer salt rejection as compared to polyamide membranes due to the presence of polymer impurities in the membrane from existing manufacturing processes. Researchers at the Bureau of Reclamation have developed a new generation of CA membranes that demonstrate higher rejection of salts than current CA membranes leading to reduction of operational cost of RO treatment.
