“…Moreover, the reported literature for EC treatment is primarily based on batch experiments [28,126,133,149,152,153], therefore reporting higher investment per small amount of water to be reclaimed. An analysis of reactor design, hydrodynamics, applied current or potential, and treatment effectiveness shall be performed [104,181]. Thus, the prioritization of research focusing on the continuous treatment of real wastewater at higher fluxes should be further explored to clearly define the limit capacity of EC.…”
