The anodic oxidation and ozonation techniques for the reduction of Tot
al Organic Carbon (TOC) in phenol-containing wastewater have been stud
ied. The effects of applied current, initial phenol concentration, sur
face area of anode, and time of ozonation on the TOC removal have been
investigated. The percentage TOC removal increased with increasing ap
plied current, anode surface area, and as initial phenol concentration
increased up to 800 mg.l-1 using anodic oxidation technique. The perc
entage of TOC removal also increased iwth increasing time of ozonation
, initial phenol concentration, and decreased as the pH of the solutio
n is increased. Values of up to 65% TOC removal have been achieved.
