Dependence of Order of Reaction on Ph and Oxidation-reduction Potential in the Ozone-oxidation of Textile Dyes in a Bubble Column Reactor

A large amount of effluent is generated in textile industries. Dyes used in the dyeing stage of a textile industry is a constant, ardent and keen source of concern to the environmental scientist. This dye effluent cannot be degraded through primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment encompasses activated sludge process. So the importance, urgency and vision of a tertiary treatment process such as ozone-oxidation. 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. 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,mission and goal of the area of tertiary treatment by ozonation will be greatly enhanced if the research endeavour progresses with the help of a tool such as bubble column reactor.
