Removal Kinetics and Performance Evaluation of 3D Rotating Cylindrical Anode Reactor for Textile Wastewater Treatment

The removal kinetics of a batch electrocoagulation 3D rotating cylindrical anode reactor for reactive dye effluent was investigated. The cell used a new type of electrode arrangement having a rotating 3D Al cylinder as anode and long rod of aluminium as cathode. The performance of the reactor was studied via various operating parameters, such as current density, anode rotation speed, duration of electrolysis, nature of supporting electrolyte and rate of reaction. The dye removal process in this innovative system follows a second order kinetics with maximum COD removal of 96.40% in a pH range of 6-8 and having a current density of 6 mA/cm². The anode rotation provides the turbulence which helps in removal process.
