A hybrid desalination pilot plant combining adsorption and multi-effect distillation cycles is under construction at KAUST. The integration aims to improve water production yields by up to three times using the same heat resource. The project is funded by a 2013 OCRF grant and builds upon previous research with a solar-powered adsorption pilot plant. Why it matters: This initiative advances sustainable desalination technologies, crucial for water security in arid regions like Saudi Arabia.
KAUST's Water Desalination and Reuse Center (WDRC) is developing solar-powered seawater desalination technologies, including the MEDAD cycle which combines adsorption desalination (AD) and multi-effect distillation (MED). The MEDAD cycle, developed by Professor Kim Choon Ng, doubles water production at the same temperature, reducing costs to $0.48/m3 compared to $1.201/m3 for multi-stage flash distillation. A 100 m3/day commercial-scale MEDAD project was commissioned in Riyadh in 2017 in collaboration with KACST, and a larger 2,000 m3/day project is planned for Yanbu. Why it matters: This highlights Saudi Arabia's move towards sustainable energy and the role of research institutions like KAUST in developing cost-effective desalination technologies suitable for the region.
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's Water Desalination and Reuse Center (WDRC) pioneers industry partnerships through its Center Industry Affiliates Program (CIAP). The program aligns industry interests with KAUST's research in desalination, wastewater reuse, new materials, hydrologic systems, and sustainable water technologies. Pilot plants enable intermediate-scale research and long-term assessments, bridging the gap between bench-scale testing and industrial implementation. Why it matters: This applied research model strengthens KAUST's impact on water sustainability challenges in Saudi Arabia and beyond.
A KAUST project on "Hybrid Multi-Effect Adsorption Desalination" won the Global Technology Challenge at the Saudi Water & Power Forum. The competition, launched by Aramco Entrepreneurship and GE ecomagination, focused on seawater desalination using renewable energy. KAUST's Water Desalination and Reuse Center (WDRC) is partnering with the National University of Singapore (NUS) to bring this technology to Saudi Arabia. Why it matters: This award highlights innovation in desalination, a critical area for Saudi Arabia given its high salinity seawater and need for sustainable water solutions.
