Abstract:
Printing press effluent contains high concentration chromium and copper. Due to chromium and copper are major component in industrial operation. The propose of this study is continuous removal of chromium and copper from wastewater by electrochemical using graphite electrodes and Fixed flow rate 5.6 ml/min Experiment was divided into 3 parts First, experimental study of optimum reactor. Second, experimental study of optimum electrolyte. and Third, experimental study of optimum current density. The results show that first, The optimum reactor is left-right baffled channel can remove chromium and copper passed the control of industrial effluent standard allow to chromium and copper not exceed 0.25 and 2.00 mg/L at 20 and 30 min respectively Second, Using of NaCl 0.5 M showed better result. and Third, Choose the condition channel 2, 3 and 4 provide current density 7, 5 and 0 A/m2 respectively cause low consumption energy and low cost.
