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 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.
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.
KAUST's Sciencetown Episode 25 features Professor Pascal Saikaly discussing novel wastewater treatment approaches at KAUST's Water Desalination and Reuse Center. The episode highlights innovative methods for producing clean water for non-potable uses like irrigation. A recently installed portable pilot plant is designed to provide sanitation for rural Saudi areas with reduced costs. Why it matters: This showcases KAUST's contribution to sustainable water solutions, crucial for water-scarce regions like Saudi Arabia.
KAUST's Water Desalination and Reuse Center (WDRC) is expanding its partnership with the Saline Water Conversion Corporation (SWCC). The collaboration aims to advance water desalination technologies in line with national priorities. The partnership will also focus on training the next generation of experts in the Kingdom. Why it matters: This expansion strengthens Saudi Arabia's focus on sustainable water solutions through research and development.
QualSens, a KAUST startup, is developing a smart sensor for monitoring and enhancing process control in water desalination systems. The sensor uses fluorescent enzymatic sensing to detect bacterial activity and fouling at an early stage. The system alerts operators to start cleaning the system based on the sensor feedbacks, helping to decrease energy demand for drinking water production. Why it matters: This technology could significantly improve the efficiency and reduce the costs of desalination, a critical process for water security in the Middle East.
KAUST researchers are addressing the challenge of growing electricity consumption in cooling technologies, as the global demand for air conditioning increases by 3-4% annually. In Saudi Arabia, cooling systems account for up to 70% of electricity usage during the summer. Researchers at KAUST's Water Desalination and Reuse Center are exploring ways to improve the energy efficiency of chillers to reduce costs and CO2 emissions. Why it matters: Improving cooling efficiency is critical for reducing energy consumption and carbon emissions, especially in hot climates like Saudi Arabia and other GCC countries.
