Core Viewpoint - Toray Industries has developed a highly efficient ultrafiltration membrane that maintains high permeability while reducing the load on subsequent reverse osmosis membranes, leading to stable long-term production of high-quality reclaimed water [1] Group 1: Technology and Innovation - The new ultrafiltration membrane technology can lower water treatment costs and reduce carbon dioxide emissions from the replacement and disposal of reverse osmosis membranes by over 30% [1] - Traditional ultrafiltration membranes struggle to remove common biopolymers in wastewater, necessitating frequent chemical cleaning of reverse osmosis membranes, which increases both water production costs and carbon emissions [1] - Toray's membrane structure was carefully evaluated based on observations from large synchrotron radiation facilities and simulation technology, allowing for precise control of polymer materials and manufacturing processes [1] Group 2: Performance and Applications - The newly developed ultrafiltration membrane achieves superior removal performance and high permeability, with test results showing that it can reduce the permeation of pollutants to less than one-third of Toray's existing products [1] - This technology is applicable in the treatment of domestic wastewater as well as the reclamation of industrial wastewater in sectors such as chemicals, steel, and textiles, reducing the need for chemical cleaning and operational issues associated with reverse osmosis membranes, thereby extending their lifespan [1]
