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.
Researchers developed a two-stage AI pipeline to predict desalination performance efficiency losses due to climate factors in the UAE, achieving 98% accuracy. The model forecasts aerosol optical depth (AOD) and uses it to predict desalination efficiency, incorporating meteorological data. A dust-aware control logic was developed to optimize plant operations, and an interactive dashboard was created for decision support.
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.
Al-Miyah Solutions, a KAUST spin-off, has installed a decentralized wastewater treatment unit in Rabigh, Saudi Arabia. The mobile, modular technology converts wastewater into reusable water for areas lacking centralized sewer access, addressing a need for 40% of Saudi households. The technology, developed at KAUST's Water Desalination and Reuse Center, uses aerobic granular sludge and gravity-driven membrane filtration. Why it matters: This deployment offers a sustainable and cost-effective solution for wastewater treatment and reuse in remote areas of the Kingdom, reducing reliance on costly centralized systems.
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 Associate Professor Peiying Hong has developed a wastewater treatment method using anaerobic membrane bioreactor (AnMBR) technology, which converts organic carbon into methane. In partnership with MODON, a pilot program is operational in Jeddah, treating 23,000 liters of wastewater daily using UV light and hydrogen peroxide for disinfection. This system produces clean water suitable for agriculture and biomass for fertilizer, with a smaller footprint and lower energy consumption than traditional aerobic methods. Why it matters: The AnMBR technology aligns with Saudi Vision 2030's water reuse objectives, reducing reliance on energy-intensive desalination and offering a sustainable solution for water-stressed regions.
KAUST researchers have discovered that the bacterium Enterobacter sp. SA187, found in desert plants, enhances plant salt tolerance by triggering sulfur metabolism. Salt stress prompts the bacteria to release sulfur metabolites, which then generate the antioxidant glutathione in the plant, protecting it from salt-induced damage. A KAUST startup aims to commercialize SA187 as a probiotic treatment for seeds and crops. Why it matters: This research offers a biotechnological approach to enable saline agriculture, which is crucial for water-scarce regions like Saudi Arabia that rely on energy-intensive desalination.
KAUST and NEOM have signed an agreement to establish the KAUST-NEOM Center of Excellence for NEOM Research at KAUST. The center will focus on solutions for challenges in sustainable energy, urban planning, agriculture, seismology, water desalination, AI, big data, and sensors. NEOM will be backed by over $500 billion in funding. Why it matters: The partnership signifies a major investment in R&D and technological innovation within Saudi Arabia, aligning with the Kingdom's vision for economic diversification and development of cutting-edge technologies.
