Investigation of Electrochemical Variables and Performance of a Continuous Upflow Electrocoagulation Process in the Treatment of Reactive Blue 140
This study presents an investigation of electrochemical variables in the operation of a continuous upflow electrocoagulation process in treating textile wastewater. Reactive Blue 140, which is porphyrin‐based, was used as a representative dye in the experiments. The optimal values of the design and operating parameters were found, from a batch mode, to be the following: iron anode, distance between electrodes of 8 mm, current density of at least 30 A/m2, and contact time of at least 5 minutes. These optimal values were used to design a continuous upflow electrocoagulation reactor. The pattern of liquid flow within the upflow reactor was studied using a computational fluid dynamics (CFD) program, which simulated the flow behavior inside the reactor using the finite volume method. For optimal parameter values, the water passing the electrode plates had a uniform distribution, and the reactor performance was satisfactory, with >90% color removal and energy consumption of approximately 1.4 kWh/m3.
