Membranes to Secure Safe
Drinking Water for Everyone

Many regions in the world rely on seawater to obtain drinking water. However, typical desalination processes consume a great deal of energy in order to generate the higher pressures needed to desalinate seawater with a high salt content.

Using its background as a pioneer in the field of reverse osmosis (RO) membranes, Toray is developing water treatment membranes that filter seawater at lower pressures. These original membranes reduce energy consumption and bring down energy costs for producing drinking water in countries and regions that rely on seawater desalination, such as the Middle East. Toray will continue developing RO membranes that deliver equivalent performance at lower pressures.

In 2016, Hitachi, Ltd. adopted Toray's RO membranes for use in its water treatment systems, developing energy-saving seawater desalination plants and launching a pilot plant in Saudi Arabia. Toray will continue to develop low-cost, environmentally friendly solutions for producing clean, safe drinking water, helping to remedy the anticipated depletion of water resources.

Looking to Toray to Develop Solutions for Even Greater Performance and Functionality

Population growth, climate change, and economic growth in emerging countries are all contributing to acute water scarcity issues worldwide. More seawater desalination plants are being built to address the problem, but there is a great need to improve the energy consumption and environmental impact of these plants.

Toray is making the most of its original technologies to develop high-performance solutions that help address social needs like this one. Hitachi is also striving to develop systems that best leverage the performance of these newly developed solutions. We look forward to more innovation from Toray, yielding even greater performance and functionality.

The Toray Group is moving forward with water recycling strategies in order to address the increasing water needs accompanying the growth of its business. The Group is focused on securing environmentally friendly water sources and effectively utilizing water resources.

For instance, the Toray Group has installed water treatment facilities at its plant in Mexico to enable the self-sufficient supply of industrial water used by the plant. The system uses RO and ultrafiltration (UF) membranes to mainly treat on-site well water and spent water from the plant, producing 2,000 m3 of industrial water per day.
