Abstract:

Increasing attention, interest and demand by public for a cleaner environment have been a global concern now-a-days. Besides municipal discharges, industrial point sources make substantial contribution to the pollution of river waters releasing a wide range of organic contaminants. Pulp and paper industries are water intensive industries, releasing a lot of pollutants to water bodies with significant colour load. Although many process modification technologies and /or end-of-pipe treatment methods have been implemented out to satisfy the pollution discharge limit, still there is a search of proper technology for colour reduction in industrial scale. The oxidation of pollutants from pulp and paper industry post oxygen stage effluents has been done by ozonation to reduce the colour load. The kinetics of decolourization has been studied. The ozonation reactions follow a first order disappearance of colour and the first order rate constant increases with increase in ozone concentration. Ozonation in presence of catalytic amount of Fe3+ & TiO2 enhanced the colour reduction efficiency significantly. It is found that the ozonation of intermediate stage effluents having high colour load is more effective towards ozonation.
