DuPont has been awarded a three-year, $1.3 million USD grant from PUB, Singapore’s National Water Agency on behalf of National Research Foundation, Singapore (NRF) to determine how Closed Circuit Reverse Osmosis (CCRO) technology can be applied to desalination processes to make the purification of seawater more energy efficient, flexible and reliable.

DuPont Water Solutions, a leading manufacturing of reverse osmosis and desalination membranes, obtained the globally patented and unique CCRO process technology with the acquisition of Desalitech Ltd. in January 2020. CCRO leverages a standardized design, a smart software, and standard components to help customers purify and reuse more water through higher recovery rates, lower energy consumption and reduced maintenance compared to traditional reverse osmosis. CCRO has proven to deliver up to 90-98 percent water recovery with reduced energy usage and superior fouling and scaling resistance for the purification and reuse of brackish water within industrial, municipal, and wastewater applications.

The grant will enable DuPont to continue to advance and expand the applications of the CCRO technology to bring its benefits to desalination processes and make it commercially viable for seawater reverse osmosis systems. Through this project, the CCRO technology will be optimized for seawater desalination systems to operate at 15 percent or lower energy than conventional reverse osmosis systems using energy recovery devices. The project also intends to demonstrate additional benefits of minimizing maintenance through fewer cleanings, and the ability to automatically adapt to variable salinity feed source. Closed circuit reverse osmosis desalination systems, as more autonomous, data-driven solutions, will be well suited to support the clean water needs of regions with limited access to water operations and affordable energy.

“DuPont is working to help solve global water challenges with a sense of urgency,” said HP Nanda, global vice president, general manager, DuPont Water Solutions. “As we look to increase access to fresh water, we believe that closed circuit reverse osmosis will prove to be a more sustainable way to purify, conserve and reuse water, including saltwater.”

“We look forward to working with PUB, Singapore’s National Water Agency, to advance CCRO and membrane technologies to enable a seawater reverse osmosis (SWRO) desalination system with record-setting lowest energy consumption,” said Gary Gu, global technology leader, DuPont Water Solutions. “DuPont is fully committed to supporting Singapore in our shared sustainability journey through innovation and collaboration.”

The grant is part of Singapore’s Competitive Research Programme (Water) that supports Research and Development (R&D) for technologies with great potential to transform the water industry.
