Modeling of enteric virus inactivation in fecal sludge

Microbiological prediction model-based infection risk management must be established to ensure the safety for the handling of fecal sludge in the Sanitation Value Chain. Although alkaline treatment and urea treatment are one of the most common practices for on-site treatment, emergence of a resistant population to alkaline and ammonia are still not examined. This study aims to construct pathogen inactivation model for on-site treatment and propose nondeterministic standard criteria in disinfection process, considering resistance of possible population. Furthermore, this study aims to identify a mutation on viral genome in order to elucidate the possible resistance and the resistance acquisition mechanism.
