Abstract

Tese de doutoramento em "Chemical and Biological Engineering"Filamentous bulking and the presence of emergent antibacterial micropollutants in wastewaters are problems that a wastewater treatment plant (WWTP) may deal with. The present work aimed to give additional contributions to solve the problem of filamentous bulking in sequencing batch reactors (SBRs) through the addition of biofilm carriers as well as, to provide useful data for the application of biofilms in SBRs operated in the presence of antibiotics. The influence of the organic loading rate (OLR) on the overgrowth of filamentous organisms was assessed by operating three SBRs fed with different acetate loading rates: 4.3 ± 0.3 g COD L-1 day-1 (control unit), 1.0 ± 0.1 g C...
