Toray's Water Treatment and Membrane Technology Solves Global Water Problems

摘要

Toray began research and development on membrane technology in 1968 and produced Japan's first reverse osmosis (RO) membrane in 1978. The ROMEMBRA, as it is referred to, employs spiral wound RO membrane that is resistant to impurities and can extract great amounts of water. At the dawn of membrane technology in the late 1960s, Toray began research on the most difficult of separation membranes, the RO membrane, and expanded its repertoire to include nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF). Toray gained experience in many fields of membrane technology, including ultra fine-fiber development, cultivation of polymer synthesis and polymer processing technologies. Toray currently is one of few companies in the world producing all four membrane types.
