The aim of this study is to decolorize reactive dyeing effluent by of solar based photo-Fenton process coupled with lime flocculation, with an objective of reducing reagent requirement of Fenton process and improve the pH of the treated effluent. Coupling with lime flocculation has reduced forty percent of H2O2 reagent requirements of photo-Fenton process for 98% decolorization of simulated reactive dyeing wastewater after a reaction period of 60 minutes and improved effluent pH. It is clear from the literature survey that greater reagent dose of Fenton process is required to decolorize reactive dye effluents containing auxiliary chemicals compared to aqueous solution containing reactive dye alone, due to the inhibitive effect of excess chloride ion present in wastewater. Burnt clay bricks made from chemical sludge, produced during lime flocculation, by replacing 20% of brick earth have the same properties as a standard burnt clay brick and are acceptable from environmental point of view. © 2006-2020 Asian Research Publishing Network (ARPN).
