KAUST researchers have developed a method using high-intensity pulses of light to remove carbon-based organic micropollutants from wastewater. By using a pulsed light system previously used for semiconductor materials, the team dramatically accelerated the photodegradation treatment. The high-intensity pulsed light (HIPL) triggers decomposition of organic micropollutants (OMPs) with extraordinary degradation rates within milliseconds. Why it matters: This treatment offers a potentially scalable solution to the increasing environmental problem of OMPs in waterways, addressing a critical need in water treatment technologies for the region.
KAUST researchers have discovered that combining ultraviolet sunlight with phages increases the susceptibility of antibiotic-resistant bacteria to sunlight disinfection. This breakthrough addresses the growing threat of antimicrobial resistance, as the rate of discovering new antibiotics has slowed. The team demonstrated this method's effectiveness against a pathogenic E. coli strain found in Saudi wastewater. Why it matters: This research offers a promising alternative to traditional antibiotics, particularly relevant in regions like Singapore and the GCC where treated wastewater is a crucial water supply source.
KAUST researchers have developed a novel wastewater treatment method that recovers energy while removing ammonium. The process harnesses anammox bacteria to oxidize ammonium and generate electrical current or hydrogen gas. Pilot-scale reactors are being tested at KAUST, coupled with photovoltaic panels for solar-powered wastewater treatment. Why it matters: This approach could lead to more energy-efficient and sustainable wastewater treatment, aligning with circular economy principles.
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 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.
