Study of performances, stability and microbial characterization of a Sequencing Batch Biofilter Granular Reactor working at low recirculation flow

Abstract

The Sequencing Batch Biofilter Granular Reactor (SBBGR) is a promising wastewater treatment technologycharacterized by high biomass concentration in the system, good depuration performance and lowsludge production. Its main drawback is the high energy consumption required for wastewater recirculationthrough the reactor bed to ensure both shear stress and oxygen supply. Therefore, the effect of lowrecirculation flow on the long-term (38 months) performance of a laboratory scale SBBGR was studied.Both the microbial components of the granules, and their main metabolic activities were evaluated (heterotrophicoxidation, nitrification, denitrification, fermentation, sulphate reduction and methanogenesis).The results indicate that despite reduced recirculation, the SBBGR system maintained many of itsadvantageous characteristics.
