Bioethanol industries generate a large volume of high strength wastewater called vinasse. This study compares the performance of microbial fuel cells (MFCs), inoculated with a single‐strain or a binary consortium, to produce bioelectricity while simultaneously reducing the COD levels and removing the vinasse color. The MFCs achieved the power density of 124.0 ±0.2 mW/m2 when inoculated with a strain...
In this work, chemical oxygen demand (COD) removal and decolorization of polyester scouring effluent by coagulation-acidation have been studied experimentally. Acidulated bentonite was used as coagulant. The effects of bentonite dosage, PAM dosage, stirring time, and pH after acidation on the efficiency of COD and color reduction were studied by orthogonal methodology. Finally the optimum conditions...
Color is one of the main problems in wastewater and many techniques can be applied to remove it. In this work, nanofiltration, coagulation–flocculation and their combination were studied to remove color from five reactive dyes. Nanofiltration was carried out using an energy saving nanofiltration membrane in a 0.5L pilot plant at 10bar. Coagulation–flocculation experiments were performed in a jar test...
