Therefore, the landfill leachate is a serious environmental priority. The characteristics of the leachate are mainly related to the high ammonia concentrations, the low bioavailable carbon, the heavy metals and the inorganic salts. Consequently, the biological activated sludge treatment of landfill leachate is considered a low efficiency process in terms of nitrogen removal and of aeration transfer capacity and it is characterized by elevated stripping of ammonia. For these reasons, best operative practices have to be performed for the optimization of the removals and for the energy savings when, as in this case, the biological process is applied. First of all, the increment of the soluble free ammonia (up to NH3 of 13.9 mg/L) coupled with the dissolved oxygen limiting conditions (
