Title: Remediation of Kraft effluent by ozonation: Effect of applied ozone concentration and initial pH
Author: Assalin, MR

Abstract: In this study, the impact of ozone concentration (14 and 7mg/L-1 applied for 120min) and pH (10 and 12) on color removal, and reduction of dissolved organic matter (DOC) and total phenol of Kraft El effluent was investigated. The degradation kinetics for the all parameters at pH 12 were slower than of those at pH 10. The degradation at pH 10 ceased after approximately 120min, while for the ozonation at pH 12, ozone was still being consumed even after 5 h of treatment. When the ozone dose was increased, the removal efficiency increased; however, the DOC removal efficiency continued limited.
