Abstract: Ammonia-based feedback aeration control could avoid an unnecessary air supply and, therefore, save energy. However, this control method could be impacted by many factors such as solids retention time (SRT), nitrite oxidation ...

Abstract: Effects of solids retention time (SRT) on both steps of the nitrification process (e.g., ammonia oxidation and nitrite oxidation) and the nitrifier community in a complete-mix activated sludge process were studied. At a ...

Abstract: Weighted total least-squares (WTLS) adjustment is a rigorous method used for estimating parameters in the errors-in-variables (EIV) model. However, its computational efficiency is limited due to the large number of matrix ...

Abstract: A novel wastewater treatment configuration—the Baffled Bioreactor (BBR)—was tested for municipal wastewater treatment at pilot-scale. This patented BBR is characterized by a hydraulically driven sludge recycling mechanism ...
