Removal of color and cod in ozonation process treating corrugated boxes manufactory wastewater

Abstract

This research aims to study the removal of color and chemical oxygen demand (COD) from the corrugated industry with the ozonnation. The use of ozone with capacity in the range of 24.5-59.0 mg per hr. By studying the factors and conditions that are suitable for the treatment of COD in wastewater which consists of the following factors.pH 4, 7 and 10 ozone exposure period of 120 minutes and initial COD concentration of 200-720 mg per liter. Have conducted experiments using real wastewater from the plant mentioned above affect the performance of the reactor COD with the ozonnation. At pH 4 to provide maximum efficiency in the treatment of COD compared to pH 7 and pH 10. In addition, the concentration of the starting COD higher performance of the reactor is reduced. The results suggest that, the treated of COD up to 81.6 percent. COD in wastewater treatment is started at 200 mg per liter. When the concentration of COD in wastewater from the 450 mg and 720 mg per liter. Found that the performance of the reactor, the COD decreased to 71.2 and 64.4 percent, respectively. For effective treatment of wastewater with turbidity and color ozone process Nation to be aligned with the performance of the reactor COD. The performance of the reactor is decreased when the concentration of the starting COD higher
