Saudi Arabia has announced the establishment of a new International Water Research Center in partnership between the Ministry of Environment, Water and Agriculture and KAUST. The center will serve as a global platform for applied water research, addressing water economics, security, pollution, and digital monitoring. Headquartered at KAUST, the center seeks to foster national and international cooperation, leveraging KAUST's resources to develop sustainable solutions for water challenges. Why it matters: This initiative signals Saudi Arabia's commitment to addressing critical water challenges and solidifying its leadership in water research and technology within the region.
A KAUST and King Abdulaziz University research team is using superhydrophobic sand to grow crops like tomatoes with less water. Superhydrophobic sand reduces water consumption in agriculture, the world's largest consumer of freshwater. The sand was developed by KAUST's Himanshu Mishra and Ph.D. student Adair Gallo Junior. Why it matters: This research offers a promising solution for water conservation in agriculture, especially in arid regions like the Arabian Peninsula, addressing critical water security challenges.
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.
KAUST student Adair Gallo Junior won best poster at the Water Arabia Conference. The poster presented a patent-pending technique developed in Prof. Mishra’s Group. The technique reduces water evaporation from soils. Why it matters: This award recognizes innovative research at KAUST focused on addressing critical water resource challenges in arid regions.
KAUST Assistant Professor Peiying Hong is researching methods to improve the safety of treated wastewater for reuse, motivated by increasing global water scarcity. Hong's work builds on Singapore's success in achieving water self-sufficiency through desalination and wastewater treatment. She aims to apply similar solutions to address water scarcity in countries like Saudi Arabia, where freshwater is limited. Why it matters: This research addresses critical water security challenges in water-stressed regions like Saudi Arabia and promotes sustainable water management practices.
KAUST researchers are developing new solar desalination methods to increase efficiency and minimize heat losses, building on techniques dating back to Arab alchemists. KAUST Associate Professor Peng Wang and his team at the Water Desalination and Reuse Center are developing an innovative system that more efficiently vaporizes water using interfacial heating. The design uses a photothermal material to capture the entire spectrum of sunlight and convert it into heat with nearly 100% efficiency. Why it matters: This research could provide more sustainable and efficient methods for producing fresh water in arid regions like the Middle East.
KAUST's Water Desalination and Reuse Center (WDRC) held a research conference on wastewater treatment from March 27-29. The conference covered innovations in technologies and microbes to recover resources from wastewater. Keynote speakers included Bruce Rittmann, Bruce Logan, and Jurg Keller, with topics ranging from microbial fuel cells to microalgal biotechnology. Why it matters: The event highlights KAUST's focus on sustainable technologies for water management, addressing critical resource challenges in arid regions.
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.
