Studies on Degradation of Reactive Dyes in the Textile Dyeing Effluent in a Solar Photo Fenton Process Coupled with a Sequential Batch Reactor

Abstract

Effective management of water resources and control of water newlinepollution are becoming increasingly important for a healthy environment. Due newlineto industrialization, water sources are polluted to a considerable extent. newlineAlthough various industries are responsible for discharging hazardous newlineorganic wastes in to our water resources, the textile industry is of major newlineconcern. Since these textile industry wastewaters pose a high threat to the newlineaquatic systems, intensive research for novel technologies that pursue easy newlinedegradation of such substances with higher efficiency has been stimulated. newlineA promising way to perform the degradation of these types of newlinerecalcitrant pollutants is by the application of Advanced Oxidation Processes newline(AOPs), which are well known strong technologies for waste treatment newlinepurposes. Though, from an application point of view, they still require further newlineadvancement and refinement. A new promising application field is their newlineintegration with biological treatments, which allows taking advantage of the newlineindividual potentialities of each other. newlineIn this research, a new catalyst, steel scrap, has been employed as newlinepart of the Fenton process, replacing the conventional Fenton catalyst. newlineDegradation study of textile dyeing effluent has been conducted using three newlinelight sources viz., room, UV light and solar light sources. In order to meet the newlineregulatory requirements in terms of colour and COD removal, a biological newlinetreatment under the Sequencing Batch Reactor (SBR) was coupled to the solar newlinephoto-Fenton, with steel as the catalyst. newline
