Fig nbsp xA Effect of current density and treatment time

DOC removal efficiencies were also in the range of about 75–80% in 10–15 min for all the values of i studied. However, a current density of 100 A/m2 and a treatment time of 10 min were chosen as optimum values (92% CODMn and 79% DOC removal, respectively), taking into account the color remaining in the SWW (as discussed in Section 3.1.2), removal efficiency and electricity and anode metal consumption.
