The monopolar electrocoagulation unit consisted of ten electrodes,
each electrode was 120mmh70mm, the electrodes were dipped in the electrochemical reactor to a depth of 80 mm,
and the distance between electrodes was 10 mm. In this discontinuous system, 1 liter leachate was injected into the
water cell and the solution was agitated with a magnetic stirrer bythe speed of 200 rpm. During the experiments, we
changed the electrode material, current density, electrolysis time, pH of solution and concentration of Cl
-. After 90
minutes settling, we measured the COD and NH3-N of the effluent.
