Quantifying and assessing wet-weather resilience of urban water resource recovery facilities

There is a need to advance the resilience of wastewater treatment systems to extreme weather events because many cities are expected to experience an increase in intensity of extreme rain events coupled with a decrease in the number of rainy days [1]. In this study, we use process models to quantify wet-weather resilience for suspended growth, activated sludge as well as for two biofilm technologies: the moving bed biofilm reactor (MBBR) and the membrane aerated biofilm reactor (MABR). From this, we will have a better understanding of how resiliency metrics are used to numerically quantify resilience, using historical flow data.
