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.]]></p></abstract>

El reactor tuvo una capacidad de 14.4 L con lodos y carbón activado del 40% de volumen, con una carga orgánica de 6 Kg DQO/m3 - día y un tiempo de retención hidráulica de 1 día con un flujo ascendente. El objetivo fue medir la eficiencia de la remoción anaerobia del colorante en un tiempo de 28 días. Los resultados demostraron un incremento del 41% de los Sólidos Suspendidos Volátiles (SSV) de 12894 mg-L-1 a 21546 mg-L-1 bajo las condiciones del experimento, con una remoción del 57% de la Demanda Química de Oxigeno (DQO) de 484 mg-L-1 a 122 mg-L-1 y una remoción del 87% del colorante azul directo brl de 69.61 mg-L-1 a 9 mg-L-1.
