Industrial Wastewater Treatment by Electrocoagulation-Direct Anodic Oxidation System

摘要

This paper shows the results of experimental investigations in industrial wastewater treatment by electrochemical processes, the first one uses iron electrocoagulation and the second employs boron-doped diamond electrooxidation. The coupled treatment reduced chemical oxygen demand (COD) by 99 %, color by 100 % and turbidity by 100 %. The initial and final quality levels in the wastewater were monitored using UV-Vis spectrometry and cyclic voltammetry.
