- Abstract
- An innovative process based on ozone-enhanced biological degradation, carried out in an
aerobic granular biomass system (SBBGR e Sequencing Batch Biofilter Granular Reactor),
was tested at pilot scale for tannery wastewater treatment chosen as representative of
industrial recalcitrant wastewater. The results have shown that the process was able to
meet the current discharge limits when the biologically treated wastewater was recirculated
through an adjacent reactor where a specific ozone dose of 120 mg O3/Linfluent was
used. The benefits produced by using ozone were appreciable even visually since the final
effluent of the process looked like tap water. In comparison with the conventional treatment,
the proposed process was able to reduce the sludge production by 25e30 times and
to save 60% of operating costs.
Molecular in situ detection methods were employed in combination with the traditional
measurements (oxygen uptake rate, total protein content, extracellular polymeric
substances and hydrophobicity) to evaluate microbial activity and composition, and the
structure of the biomass. A stable presence of active bacterial populations was observed in
the biomass with the simultaneous occurrence of distinctive functional microbial groups
involved in carbon, nitrogen and sulphate removal under different reaction environments
established within the large microbial aggregates. The structure and activity of the biomass
were not affected by the use of ozone. (literal)
