Removal efficiency (RE, %) of different parameters by T1 (acid precipitation at pH = 2.6), T2 (fenton oxidation for 120 min), and T3 (electrocoagulation by 500 mA). EC, TS, TOC, TN, and TP. Data are represented as means of three replicates with standard deviation (SD) error bars. The same letter in the same parameter indicates no significant difference at p ≤ 0.05
