Anaerobic Treatment of Dye Wastewater using Upflow Anaerobic Sludge Blanket Reactor

Abstract

The textile dye wastewater removal in the environment is a greater problem by its harmful reasons. Dyes which obstruct the penetration of light leads to damage the quality and produce the poisonous effect in the aquatic ecosystem. Several studies were proved that the physicochemical methods were employed for treating the textile dye wastewater. Hence the biological processes are employed for treating the textile dye wastewater due to its cost effectiveness and less toxic effects. Bio filter can be an effective solution for producing high quality water and saving water for recirculation. In this article fujino spirals were mainly focusing as media in the reactor and operated at a hydraulic retention time (HRT) of 24h. The purpose of this study to analysis the overall performance of the UASBR which is achieved the maximum COD removal at 24hrs HRT respectively. From this study results, percentage of COD removal is directly related to the HRT. Hence the UASBR is suitable for treating real textile dye wastewater even upto 1000mg/l efficiency.
