KAUST researchers have developed an energy-efficient wastewater treatment process that generates high-quality effluent suitable for reuse. A pilot plant in Jeddah, operating since July 2022 in collaboration with MODON, treats 50,000 liters of wastewater daily off-grid, generating 1.5 kWh of electrical energy per 1,000 liters treated. The plant utilizes an anaerobic membrane bioreactor (AnMBR) coupled with UV disinfection, removing up to 99.9999% of microorganisms and producing less solid waste. Why it matters: This decentralized, energy-independent system offers a sustainable solution for water treatment in resource-scarce regions of the Middle East, aligning with Saudi Arabia's sustainability goals.
KAUST researchers have developed a passive cooling system that uses solar energy to evaporate water and regenerate salt for reuse, achieving temperatures as low as 3.6 degrees Celsius. The system uses ammonium nitrate (NH4NO3) due to its high solubility and low cost. The crystallized salt stores solar energy and can be reused for cooling when needed. Why it matters: This off-grid design offers a sustainable and inexpensive cooling solution for communities in hot regions with limited electricity access, addressing a critical need exacerbated by climate change.
Professor Peng Wang of KAUST has received the Mohammed bin Rashid Al Maktoum Global Water Award for his research using renewable energy for clean drinking water production. The award, given by Suqia UAE, recognizes projects with sustainable solutions to water scarcity, focusing on technologies that produce, distribute, and purify water using renewable energy. Wang's research focuses on leveraging solar energy to develop inexpensive, low-carbon technologies for clean water production suitable for off-grid communities. Why it matters: This award highlights the importance of innovative research in addressing water scarcity challenges in the Middle East and globally, aligning with the UAE's commitment to sustainable development goals.
