- Abstract
- This paper reports the results of an investigation aimed at evaluating the performance of
an innovative technology (SBBGR system - Sequencing Batch Biofilter Granular Reactor),
characterised by a low sludge production, for treating municipal wastewater at demonstrative
scale. The results have shown that even at the maximum investigated organic load
(i.e., 2.5 kg COD/m3 d), the plant removed 80% of COD, total suspended solids and nitrogen
content with relative residual concentrations lower than the Italian limits for discharge
into soil. The process was characterised by a very low sludge production (i.e., 0.12-0.14 kg
TSS/kg CODremoved) ascribable to the high sludge age in the system (qc >120 d). Molecular in
situ detection methods and microscopy staining procedures were employed in combination
with the traditional measurements (oxygen uptake rate and total protein content) to
evaluate both the microbial activity and composition, and the structure of the biomass.
A stable presence of active bacterial populations (mainly Proteobacteria) was found within
compact and dense aggregates. (literal)
