Investigation of Electrocoagulation Process Efficiency for Color Removal from Polyacrylic Textile Industrial astewater
Dyes due to coloring nature are appearance pollutants and destroys the transparency and aesthetic quality of surface waters even at relatively low concentration. Several processes have been used for dye removal from wastewater. In recent years, electrochemical methods have been successfully employed...

COD of wastewater was 1400mg/l. This study was conducted in laboratory scale. The sample was placed in to the electrochemical reactor contains 4 electrodes. The electrodes were connected to a DC power supply. Then the effect of the three operational parameters, electrolysis time (20-60 minutes), electrical applied current (0.5-2.5 Ampere) and pH (4-9) on color and COD removal efficiency has been investigated. The results showed that the color and COD removal efficiency is a direct relation with increasing of the reaction time and inverse relation with increase of pH. Optimum operation conditions were in applied current of 1.5 A, the retention time of 60 minutes and pH of 4. In this condition, color and COD removals were 86% and 85%, respectively.
