Many industries use dyes to color their products & also consume substantial volumes of water. Dyes are common constituents of effluents discharged by various industries, particularly the textile industry. Saving water to save the planet & to make the future of mankind safe is what we need now. Although considerable information has been collected for the adsorption of single component dyes by various adsorbents, many industrial situations involve the discharge of effluents that contain a mixture of several dyes; limited data is available on multicomponent dye adsorption. The study of multi- component adsorption presents a major challenge compared to single component adsorption mainly due to the increased complexity brought about by the increasing number of parameters needed for process description. Stirred tank and packed bed column study was carried at different parameters to investigate the competitive adsorption of Safranine and Methylene blue dyes. It was concluded that chemically modified rice husk can be an alternative economic material to more costly adsorbents used for dye removal in wastewater treatment processes.
