| Title | 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 technology
characterized by high biomass concentration in the system, good depuration performance and low
sludge production. Its main drawback is the high energy consumption required for wastewater recirculation
through the reactor bed to ensure both shear stress and oxygen supply. Therefore, the effect of low
recirculation 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 (heterotrophic
oxidation, nitrification, denitrification, fermentation, sulphate reduction and methanogenesis).
The results indicate that despite reduced recirculation, the SBBGR system maintained many of its
advantageous characteristics. |
