Development of a New Membrane with Highly Durable Reverse Osmosis and High Water Permeability used in Wastewater Treatment by TORAY
Use of Reverse Osmosis (RO) membranes have had a great success in water treatment plants in areas around the globe faced with water shortage problems, at the same time, there has been an growing demands to improve removal properties to ensure high quality water as well as enhancing water permeability capable of carrying the process with low power consumption. To meet this demand, Toray Industries has successfully developed a highly durable reverse osmosis membrane with highly water permeability capable of removing ions and organic compounds based on company’s know how in nano-technologies.
The new RO membrane is highly resistance against acids, alkali as well as chlorine which is used during cleaning operation. Inn developing the new membrane Toray has stabilized the pore structure against changing conditions through control of pore structure on a sub-nanometer scale. Toray has relied on four core technologies in developing its highly acclaimed RO membranes, which are organic synthetic chemistry, polymer chemistry, biotechnology, and nanotechnology.
