In this study, effect of the operational parameters on the EC and EF processes were evaluated based on removal efficiency and operating cost. The optimum operating conditions for LFW were determined as 50A/m2 and pH 6 for the EC process, and 50A/m2 and 25 mM of H2O2 concentration for the EF process at 45min. The EF process resulted in higher removal efficiencies (81% of TOC in 10 min, 96% of TP and 99% of color in 45min) than that of the EC process (79% of TOC, 73% of TP and 95% of color efficiency in 45 min). Amount of the sludge produced was higher in the EC process (2.42 kg/m3) than that of the EF process (0.65 kg/m3). However, the operating cost for the EC process was found to be 1.7 times lower than that of the EF process since price of H2O2 was affected the cost drastically. The obtained results indicated clearly that the EC and EF processes were very effective for the removal of LFW. Overall, the EF process was more successful for achieving higher removal efficiencies in terms of TOC, TP and color than the EC process and the EF process is a promising technology for applications in wastewater treatmen
