Abstract: Abstract In this chapter, we describe the history of development and commercialization of RO membranes at Toray. Stimulated by DuPont’s seminal achievement, Toray started its development activities for actualizing seawater desalination as a goal. We clarify that, in the middle of long-lasting development, the emergence of an ultra-pure water demand for semiconductor manufacturing provided economically viable markets and enabled Toray to continue its development. We also illustrate that a newly developed membrane, UTC-70, opened the way to the actualization of seawater desalination.
