excellent settling properties, allowing shorter settling times for
good solid–liquid separation and requiring lower construction area; good biomass retention, allowing higher concentration in
the SBR and consequently lower reaction time and/or reactor volume;
ability to withstand toxicity and high organic loading rates,
making them attractive for industrial wastewater treatment applications;
aerobic and anoxic/anaerobic zones within the granules,
allowing organic matter, nitrogen and phosphorus removal in the
same system and potentially contributing to the process of azo dye
mineralization. Given the particular attributes of aerobic granules,
this compact technology has a great potential for the treatment
of the highly variable textile wastewaters, including the biodecolorization
of textile dyes that are generally resistant to aerobic
biodegradation, like azo dyes.
Despite the increasing reported applications of AGS for municipal
and industrial wastewater, textile wastewater treatment with
this technology has scarcely been reported
