Decolorisation of Reactive Congo Red Dye Solution by Electro Coagulation Process

The decolourisation of the reactive Congo red dye from synthetic wastewater was studied using ElectroCoagulation (EC) technique. In an effort to increase removal efficiency, effects operating parameters including flow, inter electrode distance, conductivity, voltage, and Hydraulic Detention Time (HDT) were investigated. An electrochemical cell initially created with aluminum cathode anode. Following that, each variable's impact examined independently wastewater. colour efficiency 93% when initial concentration 4 mg/L, conductivity 300 ppm, temperature 24 oC, interelectrode spacing 1 cm, HDT electrolysis 120 min.
