Abstract

The experiment was conducted by using ozone and graphite electrodes to treat wastewater from industrial fried chicken re-processing peocesses with COD value ranges of 1600 - 2000 mgO2/L. A chamber of 20 liters was used in this study. The chamber height was 1 meter (the high response of 50-60 cm) in order to increase the diffusion of ozone into the wastewater. The study results showed that the amount of ozone needed for the reaction is 300 mg/h with COD removal efficiency of 40 % during reaction time of 45-60 minutes.The rate of BOD/COD increased within 1.55 - 1.80 times as compared with the BOD/COD rate of the initial wastewater. The experiments also showed that the COD removal efficiency of wastewater was not affected much by the pH value of the wastewater.
