NanoH2O has been selected to supply reverse osmosis membranes for the Tainan Seawater Desalination Plant, a landmark project in development by Cox, water and energy utility that applies innovative technological solutions for sustainable development, that will become Taiwan’s largest SWRO facility. With a daily capacity of 200 million liters, the plant will deliver safe drinking water to over one million residents and support the island’s fast-growing semiconductor industry.

For this high-profile project, NanoH2O will supply 10,400 membrane elements, including its advanced SW 440 R G2 and BW 440 ES L membranes. The second-generation SWRO membrane offers high salt rejection, optimized energy efficiency, and enables a compact system design, reducing both energy consumption and membrane footprint. Combined with the reliable performance of the brackish water RO membrane, NanoH2O’s solution met the project’s stringent technical and economic requirements.

This achievement reinforces NanoH2O’s position as a trusted provider of innovative, energy-efficient membrane technologies, and highlights its growing presence in Taiwan and the Asia-Pacific region.

As global demand for sustainable water solutions continues to rise, NanoH2O remains committed to leading the advancement of seawater desalination technologies. Through continuous innovation and proven performance in large-scale projects like Tainan, we are shaping the future of water delivering reliability, efficiency, and resilience to communities and industries around the world.
