Wet Oxidation: A Promising Option for the Treatment of Pulp and Paper Mill Wastewater

Wet Oxidation: A Promising Option for the Treatment of Pulp and Paper Mill Wastewater Wet oxidation (WO) is used to degrade persistent organic or inorganic impurities present in industrial wastewater. The process utilizes severe oxidation conditions (i.e., high temperature and pressures) to achieve the efficient degradation of pollutants. To obtain high degradation at lower operation conditions, catalytic WO process is being suggested. The wastewater generated from a pulp and paper mill contains several recalcitrant compounds like lignin, hemi-cellulose, phenols, sulfides etc. Therefore, pulp and paper mill effluent have low biodegradability and are not amenable for conventional biological process. With the implementation of stringent regulations, pulp and paper mill operators need a cleaner disposal route for the wastewater. In this mini-review, the results obtained from the recently published studies on WO treatment for pulp and paper mill effluent are compiled and presented. Finally, the recommendations for the future work are also given. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

Wet oxidation (WO) is used to degrade persistent organic or inorganic impurities present in industrial wastewater. The process utilizes severe oxidation conditions (i.e., high temperature and pressures) to achieve the efficient degradation of pollutants. To obtain high degradation at lower operation conditions, catalytic WO process is being suggested. The wastewater generated from a pulp and paper mill contains several recalcitrant compounds like lignin, hemi-cellulose, phenols, sulfides etc. Therefore, pulp and paper mill effluent have low biodegradability and are not amenable for conventional biological process. With the implementation of stringent regulations, pulp and paper mill operators need a cleaner disposal route for the wastewater. In this mini-review, the results obtained from the recently published studies on WO treatment for pulp and paper mill effluent are compiled and presented. Finally, the recommendations for the future work are also given.
