    Abstract :

    Lignin, being major contaminant in pulp and paper mill effluents, cannot be efficiently and economically removed by conventional treatment processes. Photocatalysis is a natural process of pollutant degradation in water. It has proven wide application potential in the field of water and wastewater treatment. This paper describes the performance study of Photocatalysis on the degradation of Lignin from Pulp and Paper industry wastewater. Experimentations were conducted on pure Lignin- water media to evaluate the performance of photocatalytic slurry phase reactor for Lignin oxidation. Experimentations were conducted for pH and Catalyst dose optimization. It has been found that most rapid oxidation is achieved at pH 5.5. A catalyst concentration of 2000 mg/l has optimized oxidation potential for 2% Lignin-water solution for 2 Hours of UV exposure. Utilizing the obtained optimistic values, other operational parameters can be evaluated for modeling the Photocatalytic Reactor.
