Resumo(s)
Aerobic Granular Sludge (AGS) has been successfully applied for carbon, nitrogen and phosphorous
removal from wastewaters, in a single tank, reducing the space and energy requirements. This is especially
beneficial for, often space restricted, industrial facilities. Moreover, AGS holds a promise for the toxic
pollutants removal, due to its layered and compact structure and the bacteria embedding in a protective
extracellular polymeric matrix. These outstanding features contribute to AGS tolerance to toxicity and
stability. Strategies available to deal with toxic compounds, namely granulation with effluents containing
toxics and bioaugmentation, are addressed here. Different applications for the toxics/micropollutants
removal through biosorption and/or biodegradation are presented, illustrating the technology versatility.
The anthropogenic substances effects on system performance and bacterial populations established
within AGS are also addressed. Combination of contaminants removal to allow water discharge, and
simultaneous valuable products recovery are presented as final remark.
