In this research the effect of current density and charge loading was investigated on the removal of total organic carbon (TOC)
from a synthetic water sample. It was noted that during Electrocoagulation (EC) at a constant current density, TOC removal
was increased when charge loading was increased. However, for a constant charge loading, the TOC removal was decreased
when the current density was increased. Therefore, the investigation pointed out anomalously, that the indiscriminate growth
of current density does not only decrease the TOC removal but also cause economic loss.
