ZAVALA-RIVERA, Christian et al. Anaerobic removal of the brl direct blue dye in Upflow Anaerobic Sludge Blanket (UASB) with activated carbon. Rev. colomb. biotecnol [online]. 2015, vol.17, n.2, pp.55-64.  Epub 09-Ago-2021. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v17n2.54276.

In this research the brl direct blue dye was used for anaerobic removal with a bacterial consortium of industrial effluents from Industrial Park Río Seco (IPRS), Arequipa, Peru; in an anaerobic reactor of UASB Upflow with activated carbon. The reactor had a capacity of 14.4 L with sludge and activated carbon of 40% of volume, with an organic load of 6 Kg COD/ m3-dia and a hydraulic retention time of 1 day with an upward flow. The objective was to measure the efficiency of the anaerobic removal of coloring in a time of 28 days. The results showed an increase of 41% of the solids suspended volatile (SSV) 12894 mg-L-1 up to 21546 mg-L-1 under the conditions of the experiment, with a removal of 57% of the chemical demand of oxygen (COD) from 484 mg-L-1 to 122 mg-L-1 and a removal of 87% of the dye Blue direct the 69.61 brl mg-L-1 to 9 mg-L-1. Results with activated charcoal granular only, they showed a removal of 61% of the dye Blue direct 70.67 brl mg-L-1 to 27.83 mg-L-1 at 28 days.
