Toray Develops High-Efficiency Ultrafiltration Membrane

Toray Industries has introduced a high-removal ultrafiltration (UF) membrane designed to improve wastewater reuse by reducing biopolymer contamination. The new membrane maintains high water permeability while decreasing the strain on reverse osmosis (RO) systems, helping to stabilize long-term production of high-quality water. By limiting the build up of contaminants, the technology is expected to lower chemical cleaning requirements, extend RO membrane lifespans, and cut water treatment costs.

The membrane, which was tested in pilot operations at a sewage plant, demonstrated a reduction in RO membrane fouling by one-third compared to conventional UF offerings. Toray plans to launch the product in North America in mid-2025, followed by Japan and other markets. The company presented the technology at the Membrane Technology Conference in the United States in February.

Toray say that this development supports its broader efforts to enhance water treatment efficiency and contribute to sustainability. By minimizing chemical usage and improving system performance, the company expects the membrane to help lower carbon dioxide emissions from wastewater treatment by more than 30%.
