The combination of biological nutrient removal (BNR) with fluidization technology has demonstrated advantages over suspended growth systems. Previous studies about fluidized bed bioreactor (FBBR) mainly focused on the BNR performance, rarely paid attention to the operation and energy consumption, while high energy consumption is the main hurdle for the industrial application of FBBR systems.
In this work, the BNR performance of a novel inverse fluidized bed bioreactor (IFBBR) treating synthetic wastewater was studied. TCOD removal efficiencies of ˃84% were achieved, concomitantly with complete nitrification. Compared with other FBBR systems, the energy consumption for this IFBBR system was an average 59% …
