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 and TU Munich researchers have published a paper on a novel carbon capture technique. The technique focuses on converting CO2 directly from flue gas using catalytic systems, addressing the challenge of CO2 conversion requiring purification, compression, and high temperatures. Catalysts are often seen as viable green technology options to increase the renewable rates of CO2. Why it matters: This research has the potential to advance sustainable energy solutions by improving the efficiency and reducing the environmental costs associated with carbon capture and utilization.
KAUST researchers led by Pascal Saikaly are developing microbial electrochemical technologies (METs) for wastewater treatment and energy recovery. The team combines METs with membrane filtration, creating a hybrid air-biocathode microbial fuel cell-membrane bioreactor (MFC-MBR) for simultaneous wastewater treatment and ultrafiltration. This system uses an electrically conductive ultrafiltration membrane as a biocathode for electricity generation and passive oxygen transfer. Why it matters: This innovation offers a sustainable approach to water reclamation by reducing energy consumption and producing reusable water, which addresses critical water scarcity challenges in the region and globally.
