The experiments were carried out in an electro coagulation reactor with aluminum as sacrificial electrodes. The influence of electrolysis time, current density, pH, NaCl concentration, rotational speed of the stirrer and electrode distance on reduction of color, COD and BOD were studied in detail. From the experimental results, 25mA/cm2 current density, pH of 7, 1 g/l NaCl, 100 rpm, 28 ◦C tempe...
