Studies on Ozone-oxidation of Dye in a Bubble Column Reactor at Different pH and Different Oxidation-reduction Potential

Sukanchan Palit1

Abstract—A massive and considerable amount of effluent is generated in a textile industry and allied industries. Dyes used in the dyeing section of a textile industry is a constant, intense and persistent source of concern to the environmental engineer and to the common mass in general. This dye effluent/waste cannot be degraded with the help of primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment encompasses activated sludge process. So the importance, urgency and aim of a tertiary treatment process such as ozone-oxidation or ozonation. The present research engulfs the understanding of the dependence of order of reaction on pH of the solution and oxidation-reduction potential. The research on ozonation of dye is done in a bubble column reactor-fixed bed and without media. It gives an understanding and an innovative concept that dye degradation by ozonation is highly dependent on acidity or alkalinity of solution. Investigations in the variation of redox potentials in the course of ozonation reaction is also analysed. The vision, mission and objective of the area of tertiary treatment or degradation by ozonation will be greatly enunciated if the research endeavour progresses with the help of a tool such as bubble column reactor.

Index Terms—textile, ozonation, dye, bubble column, tertiary treatment.
