About the Seminar
Frequency and magnitude of natural disasters (e.g. hurricanes) increased globally over the past century. Clean water is a top priority for disaster-affected populations. However, existing emergency water treatment (EWT) methods are not all feasible or technically effective at many emergency situations. The recent Puerto Rican water crisis after Hurricane Maria highlights research needs and new challenges for new EWT technologies. This presentation will provide an overview of currently available EWT methods and then introduce the state of EWT research at MSU. Ferrate(VI) as an emerging treatment agent was recently investigated for the treatment of simulated disaster-polluted water. Results show that ferrate(VI) treatment could simultaneously and effectively inactivate bacterial indicators, remove metal and metalloid contaminants, degrade dissolved organic matters, and reduce turbidity, while insignificantly increasing total dissolved solids (TDS) to ensure an acceptable TDS ≤ 1,000 mg/L (the recommended minimum TDS standard for emergency water supply). Different from many traditional water treatment agents (e.g. chlorine), ferrate(VI) does not produce toxic disinfection byproducts (DBPs). Therefore, ferrate(VI) opens a new opportunity for EWT to provide safe and sufficient water for disaster-affected populations and rapid disaster relief.
