Summary:Brewery waste (BW) is among the natural adsorbents that have been evaluated for different chemical pollutants removal present in the aqueous medium. In this work, we investigated the BW capacity to remove the commercial indigo blue dye (IB) from laboratory aqueous solutions and river water samples. Results utilizing laboratory distilled water showed a satisfactory maximum capacity (166.94 mg/g) of BW for IB. The ∆G value (-16.53 Kj/mol) and other parameters reveal a favorable adsorptive process. Furthermore, tests in glass columns using river water samples enriched with IB (1,000 mg/L) revealed high BW efficiency for IB removal (96.0 %). These results are important to demonstrate that BW can be more a new alternative for IB removal from water. In addition, this study provides an alternative for the reuse of BW.
