Textile wastewater treatment in anaerobic reactor: Influence of domestic wastewater as co-substrate in color and COD removal

Treatment of textile wastewater with domestic as co-substrate was investigated in this study. Combined and at different mixing ratios (100:0, 80:20, 60:40) treated under anaerobic reactor. The influence residence time, fraction initial pH were determined view COD color removal. Response Surface methodology (RSM) Box–Behnken design (BBD) employed to determine conditions for higher simultaneous removal color. highest satisfied 8.6, time 9 days while ratio 77:23. efficiencies realized 70% 72% respectively. In general, longer favored Furthermore, range 0.65 – 0.8 simultaneously high Therefore, co-digestion specific is a novel finding that can be further developed treating wastewaters. Moreover, technology promising approach enhance biological treatment wastewater.
