Abstract: In this study, treatment of simulated alkali decrement wastewater containing terephthalic acid (TPA) has been investigated by electrochemical treatment using stainless steel as electrode material. Five operational parameters, namely current density: 31.25-156.25A/m2; electrode gap: 1-2cm; NaCl concentration: 0-2g/l; pH: 7-12 and TPA concentration: 400-1000mg/l were investigated for their effect removal efficiency. For a solution having 400mg/l TPA and 560mg/l chemical oxygen demand (COD), 72% COD removal and ?77% TPA removal efficiency was obtained at optimal conditions of current density?118A/m2, electrode gap=1cm and pH?7. Presence of ethylene glycol in the wastewater was found to decrease the treatment efficiency. Settling characteristics of the slurry obtained at optimum condition have been studied. Thermal decomposition of residues has also been investigated. © 2013 Taiwan Institute of Chemical Engineers.
