Potential for Anammox Mainstream Bioaugmentation

The purpose of this research is to evaluate the effect of temperature shock (immediate activity loss) and long-term exposure (acclimation ability of the same population of biomass – long-term experiments did not allow enough time for population turn over) to reduced temperatures on AMX activity. This research aims to demonstrate that AMX activity is maintained at lower temperatures and quantify the reduction in activity by developing an Arrhenius coefficient for AMX. Determining the extent of decrease in activity (Arrhenius coefficient) will help to determine if mainstream deammonification with bioaugmentation would be successful. This study suggests that acclimation will help mitigate the effects of activity loss at lower temperatures and that AMX is able to fully and quickly recover activity loss after temperature shock. Both of these findings support the implementation of mainstream AMX.
