Dye effluent is a major hazard to the surrounding environment. This hazardous condition is inevitable but the regulation of decolorizing could be done using reactors. In this study, we have designed a Packed bed adsorption column bioreactor to decolorize the dye effluent using natural adsorbents like Limetta peel and Groundnut shell powder. The toxicity study was done with the help of microorganisms. We had used the effluent from microbiological labs from our university and we treated them at the range from 100ppm to 400ppm. Standardization of dye removal was done primarily in small scale and later implemented in a large scale setup. Characterization studies for adsorbent were done using SEM analysis to get the nature of the pore size. In this study, we chose 200ppm of dye effluent to be treated and the extraction efficiency (%) of the treated dye was observed and the adsorption isotherm was studied.
