A new insight for micropollutants in activated sludge: variability of influent concentrations and effects of operating parameters on removal performances

Une nouvelle approche des micropolluants en boues activéees : variabilité de la concentration dans l'influent et effet des paramètres opératoires sur les performances épuratrices

Résumé

We investigated how variable were concentrations in raw wastewater for 6 beta-blockers and 10 metals. Measured concentrations suggested a different consumption of 4 beta-blockers according to the season. We observed the same variability for metals. During a day, influent concentrations were not constant. However, daily concentrations seemed to be similar for consecutive days. So a robust understanding of a treatment process implied the knowledge of influent concentrations. We studied also the influence of operating conditions on micropollutant removal. We observed that a higher temperature, a lower MLSS concentration and a higher ammonium oxidation promoted micropollutant removal.
