obtained during an investigation aimed at transferring to the demonstrative
scale an aerobic granular biomass system (SBBGR – Sequencing Batch Biofilter Granular Reactor)
integrated with ozonation for the efficient treatment of tannery wastewater. The results show that the
integrated process was able to achieve high removal efficiencies for COD, TSS, TKN, surfactants and colour
with residual concentrations much lower than the current discharge limits.
