THE IMPACT OF OPERATING FACTORS ON EFFICIENCY OF COLOR TREATMENT FOR DYEED WASTE WATER BY USING ELECTROCHEMICAL FLOCCULATION

Abstract

In this study, factors affecting the efficiency of color treatment for dyeed waste water from dyeing shoelaces of Toan Hung Company by electrochemical flocculation using iron electrodes were investigated and evaluated. The results show that the current density, pH and reaction time significantly affect on the color removal efficiency. Electrical conductivity has an insignificantly effect but directly affects the power consumption. Color treatment efficiency reached over 90% when operating with a current density of 25A/m2, neutral pH, conductivity 2.5mS/cm and a reaction time of 15 minutes
