Title: Fouling and scaling resistant nano-structured reverse osmosis membranes
Usefulness: Fouling and scaling resistant nano-structured reverse osmosis membranes
Summary: For modifying a surface of a membrane or manufacturing a reverse osmosis desalination membrane useful as separation membrane for water desalination (claimed) and saline water desalting; and also useful in a reverse osmosis (RO) process, nanofiltration, and ultrafiltration.
Novelty: Modifying surface of membrane used as separation membrane for water desalination involves exposing surface to impinging atmospheric pressure plasma source to produce activated surface and exposing activated surface to vinyl monomer solution

*Abstract

Professor Cohen and his research team have developed a novel class of membranes capable of resisting organic- and biofouling, as well as mineral salt scaling. These novel membranes have applications in water treatment and desalination, where biomaterial buildup and salt scaling of reverse osmosis membranes represent major impediments to high recovery rates.
