Resumo

Textile industry is a worldwide economic activity that generates high volumes of harmful effluents used in fabric processing that are discharged in theenvironment causing potential damages to the aquatic ecosystems [1]. These discharged effluents loaded with synthetic dyes, salt and other chemicals, areresistant to biodegradation and persistent in water, and are responsible for toxicity and mutagenic effects on the aquatic life [2]. Biological methods aregenerally considered more environmentally friendly and of major relevance [3]. Therefore, biological alternatives to aid the decolorization of dyes in textilewastewaters need to be implemented. Aerobic granular sludge (AGS) technology has excellent potential in biodegradation of many pollutants, due to theanoxic/anaerobic zones within granules and their increased tolerance to toxicity [4].The aim of this study is to assess the effectiveness of decolorization of textile effluents using a bioaugmented aerobic granular sludge reactor. A proveddecolorizing yeast, isolated from a textile wastewater treatment plant, was selected for its dye decolorization capacity, and used to bioaugment the bioreactorwhile forming the granules from activated sludge. The incorporation of the yeast with the granules was followed by plating and following the yeast within themicrobial community. A commonly used textile azo dye was added to the reactor to follow the biodegradation by the bioaugmented aerobic granular sludge andthe efficiency of the process in decolorizing the effluent at varying operational parameters was followed to assess if this is a solution for a safer discharge ofsuch effluent
