In present scenario many industries use Marigold flower as raw material in manufacturing of paints, cosmetics, perfumes, medicines etc.., the waste produced from marigold processing unit is in liquid form, which possess problems with excess BOD. The treatment facilities available in the existing unit does not meet the disposal standards. The raw wastes from marigold processing unit was collected and analyzed for initial characteristics. Reduction of BOD from marigold wastes was studied by using low cost adsorbents like laterite, charcoal and rice husk. The experiment was carried out using the process of adsorption. Since laterite, charcoal and rice husk are cheaply, easily and locally available materials, it works out to by an economical methodology. The Whole study of adsorption characteristics of above pollution parameters are done in column study. To see the performance evaluation by varying rate of flow, constant rate of flow and to compare the result of Removal efficiency of laterite and Charcoal and rice husk. The efficiency of BOD removal was found to be dependent on various parameters like flow rate (l/m), depth of adsorbent, contact area and contact period and by knowing the initial and final concentration, the percentage of removal was calculated. The results obtained were positive, quite encouraging and interesting
