HRT determines production rate of the ion Fe2+ and Fe3+ from
the iron electrode. However, in our study, HRT showed no significant
effect on turbidity and TP removal using EC process, since
the slightest CD was sufficient for turbidity and TP removal. In this
way, it can be concluded that HRT of about 70.0 min and CD of
27.8 mA/cm2 are optimum for the iron electrode to the continuous
flow system proposed in this work.
