Researchers at KAUST have developed a new polymer membrane for desalination that operates at ambient temperature and pressure. The membrane achieves high salt rejection with lower energy demand compared to conventional methods. It is currently being tested at pilot scale at KAUST. Why it matters: This technology could improve water sustainability and reduce energy consumption in desalination, addressing critical water challenges in arid regions like Saudi Arabia.
KAUST researchers have developed an ultrathin polymer-based membrane for water desalination with high water flux and salt rejection. The membrane utilizes two-dimensional porous carbonaceous materials with subnanometer-sized molecular transport channels. The membrane outperformed existing desalination systems using carbon nanotubes and graphene in forward and reverse osmosis. Why it matters: This innovation offers a promising alternative for efficient and cost-effective desalination, addressing critical water scarcity challenges in the region and beyond.
KAUST researchers have developed a new solar distillation device that prevents salt accumulation by using a centimeter-scale plastic cube containing glass fiber membranes and carbon nanotubes. The design incorporates vertically oriented membranes with hydrophilic microchannels to transport seawater to the top solar layer for distillation. This elevated design doubles the freshwater production rate compared to existing salt-rejection solar stills. Why it matters: This innovation improves the efficiency and longevity of solar-powered desalination, offering a sustainable solution for water purification in emergency situations and remote areas.
