KAUST researchers are partnering with Saudi farmers and the Ministry of Environment, Water and Agriculture (MEWA) to develop tailored desalination solutions for agriculture. A new KAUST Center of Excellence project aims to integrate controlled environment agriculture (CEA) with desalination of non-conventional water resources for hydroponic farming. The approach focuses on selective ion removal to provide 'clean-enough' water, reducing energy use and costs compared to traditional desalination. Why it matters: This initiative could enable more sustainable and affordable local crop production in Saudi Arabia, potentially shifting the Kingdom from importing to exporting agricultural technologies.
KAUST researchers are developing innovative solutions for water treatment and desalination in Saudi Arabia. A pilot anaerobic membrane bioreactor in Jeddah treats 50,000 liters of wastewater daily at zero energy cost, producing water suitable for reuse and liquid fertilizer. Another KAUST team focuses on advancing desalination technologies by integrating renewable energy and reducing energy consumption and brine discharge. Why it matters: These advancements can significantly contribute to Saudi Arabia's water security and sustainability goals by reducing reliance on non-renewable groundwater and fossil fuels for desalination.
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.
KAUST researchers led by Mark Tester are developing new irrigation technology to enable crop production using semi-saline water, aiming to reduce freshwater reliance to 10% in greenhouse systems. The technology is eco-friendly and intends to cut agricultural costs by utilizing seawater, targeting a cost of 10 U.S. cents per cubic meter. A new company named Red Sea Farms is being developed to grow salt-tolerant tomatoes in diluted seawater in a greenhouse cooled with undiluted seawater. Why it matters: This research could significantly reduce pressure on freshwater resources in arid regions and offers a sustainable approach to increase food production using available seawater.
