The present study aims to examine the electro-Fenton/electro-coagulation (EF/EC) process for the treatment of wastewater generated from Kraft pulp and paper mills. As a result of the experimental studies, the optimum operating parameters of the EF/EC process have been identified as follows: current = 1.0 A, initial H2O2 concentration = 1000 mg/1 and initial pH 2.5. It has been established that, under these conditions, the COD could be removed at 91.7%. It has been understood that the sludge produced from the EF/EC reactor possesses fairly good sedimentation characteristics and is significantly affected by the operating parameters. It has been established that the best sedimentation characteristics can be achieved when the current is >= 1.0 A, the initial pH value is between 2.3 and 3.2, and the initial H2O2 concentration is between 400 and 1800 mg/l.
