Toray Develops Reverse Osmosis Membrane

Toray Industries, Inc., has announced that it has developed a highly durable reverse osmosis (RO) membrane, which they say guarantees the long-term provision of high-quality water. It also maintains the superior removal performance of Toray’s existing membranes vital for reusing industrial wastewater and treating sewage.

The company is preparing to mass produce this membrane and launch it in the rapidly expanding Chinese market in the first half of 2024. It looks to develop products with the new membrane for the global market including Japan.

The broad applications of RO membranes include desalinating seawater and river water, reusing wastewater, and producing drinking water as a technology to ensure sustainable water sources. Reusing wastewater entails treating water of diverse quality levels with RO membranes. The downside is that an increased reliance on cleaning chemicals to purge contaminants on the membrane surface to maintain their operational efficiency deforms their pores, diminishing removal performance. This has spurred demand for more resilient membranes.
