Dow Water Solutions, a business unit of The Dow Chemical Company, and PUB, Singapore’s national water agency, have signed an agreement to test-bed Dow’s next-generation FILMTEC membranes for use in water reclamation.
The joint collaborative research effort, which commenced at PUB’s Bedok NEWater plant in early October, is expected to validate preliminary data indicating that Dow’s newer 16-inch FILMTEC membrane modules are more efficient in water reclamation than current standard 8-inch modules. Once validated, the next-generation membrane technology will allow for more efficient and affordable water reclamation and reuse processes at large-scale treatment facilities.
Although not naturally blessed with an abundance of water or land, PUB has been investing in water technologies and R&D in the last four decades, and today, it has put in place a robust and diversified water supply strategy known as the Four National Taps. The four sources of water are water from local catchment, imported water, reclaimed water (branded NEWater in Singapore) and desalinated water.
In the process of finding solutions in the last few decades, Singapore has managed to turn its limitations into a strategic strength for the country and is fast becoming a global hub for water treatment products and technologies.
