Abstract

Considerable amount of effluent is generated in textile industries. This dye effluent is recalcitrant to primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment encompasses activated sludge process. So the importance and urgency of a tertiary treatment process such as ozone-oxidation. The present research encompasses the understanding of the dependence of order of reaction on pH of the solution during dye degradation. The research on ozonation of dye is done in a bubble column reactor. The effect of oxidation-reduction potential  on ozonation of dye is also studied. It gives an understanding that dye degradation by ozonation is highly dependent on acidity or alkalinity of solution. Investigations in the change of redox potentials in the course of ozonation reaction is also analysed. The vision of the area of tertiary treatment by ozonation will be greatly enhanced and enunciated if the research progresses with the help of a tool such as bubble column reactor.
