The present investigation studied the influence of time and current density for the removal of Biochemical Oxygen Demand (BOD5) and turbidity of the effluent from the paper machine of the paper company TRUPAL S.A, applying an electrocoagulation treatment. The process was carried out at different treatment times (40, 60 and 80 min) and different current density (5, 23; 10, 45; 15, 66 and 20, 90 mA/cm2). A 2, 6 L capacity batch glass material reactor was used, likewise, three iron electrodes were used as cathode and three aluminum electrodes as anode connected in parallel at a distance between electrodes of 1cm. We worked with an established pH of 5 and with a magnetic stirrer to avoid polarization of the sample during the treatment. From the results obtained, it was determined that the increase in time and current density significantly influence and increase the removal percentage for BOD...
