Peiying Hong, an associate professor of environmental science and engineering at KAUST, has won the 2019 James J. Morgan Environmental Science & Technology Early Career Award. The award recognizes her contributions to environmental science, particularly her research on wastewater and its potential for addressing global water scarcity. Hong will receive the award at the 257th American Chemical Society National Meeting & Exposition in Orlando, Florida. Why it matters: This award highlights KAUST's contributions to environmental research and its focus on addressing critical global challenges related to water scarcity and sustainability.
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 Associate Professor Peiying Hong delivered a lecture on using wastewater testing to detect outbreaks earlier. The lecture explains how wastewater testing could lead to faster detection and more effective response to future pandemics. The research was presented at King Abdullah University of Science and Technology. Why it matters: Wastewater epidemiology can provide early warnings for emerging pathogens and improve public health preparedness in the region.
KAUST Associate Professor Peiying Hong has developed a wastewater treatment method using anaerobic membrane bioreactor (AnMBR) technology, which converts organic carbon into methane. In partnership with MODON, a pilot program is operational in Jeddah, treating 23,000 liters of wastewater daily using UV light and hydrogen peroxide for disinfection. This system produces clean water suitable for agriculture and biomass for fertilizer, with a smaller footprint and lower energy consumption than traditional aerobic methods. Why it matters: The AnMBR technology aligns with Saudi Vision 2030's water reuse objectives, reducing reliance on energy-intensive desalination and offering a sustainable solution for water-stressed regions.
KAUST researchers led by Professor Pei-Ying Hong reported new insights into bacterial transformation, potentially impacting wastewater treatment policies. Professor Havard Rue's group released a new statistical package for modeling non-Gaussian datasets, compatible with commercial software. These achievements highlight KAUST's contributions to environmental science and statistical computing. Why it matters: These research outputs strengthen KAUST's reputation as a leading research institution in Saudi Arabia, with practical implications for environmental policy and advanced data analysis.
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 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.
A panel discussion on women in biology was held as part of the 2016 Fall Enrichment Program at KAUST. Jasmeen Merzaban, Ashwag Abdullah Albukhari, Bettina Berger and Peiying Hong were the speakers. The event featured successful female scientists sharing their experiences. Why it matters: Showcases KAUST's commitment to promoting women in STEM fields and providing a platform for their voices.
