Electrocoagulation is a common method for removing nitrate from water. In this research, using Design expert software and the CCD method, 48 experiments were performed in different parameters, including initial nitrate concentration in the range of 10-30 mg/L, 5-11 for pH, 2-10 cm for electrode distance, 5-30 V for voltage, and 20-120 min for process time. The electrodes were made of aluminum (anode) and iron (cathode), and the reactor volume was 2 liters. The highest nitrate removal was obtained in Ci = 16 mg/L, PH = 9.3, ED = 4 Cm, V = 23 v, ET = 90 min, reached . Then, the effect of sodium chloride salt, mechanical stirrer, and the number of electrodes was investigated in optimal points.
