The lives of humans and animals are affected straight by the amount of harmful substances in water streams. Municipal wastewaters contains dissolved pollutant can therefore contaminate water resources and causes grave water/environmental problem. In the current study, sorption capacities of Coconut Shell, Corn Cobs, Rice husk and Sugarcane Bagasse were examined for the treatment of domestic wastewater. The percent removal of Biochemical Oxygen Demand, Chemical Oxygen Demand and Turbidity increases with increase in impregnation ration and temperature. Freundlich and Langmuir isotherms were employed to the obtained data to check for fitness of the models. The percentage removal for Biochemical Oxygen Demand, Chemical Oxygen Demand and Turbidity for Rice Husk are 89%, 100% and 100%, Sugarcane Bagasse: 89%, 100% and 100%, Coconut Shell: 78%, 97% and 70% and Corn Cobs: 78%, 97% and 63% respectively. A Langmuir and Freundlich model adequately fits the adsorption data with coefficient of determination (R2) near unity. The present data confirms that activated carbon from Rice Husk, Sugarcane Bagasse, Coconut Shell and Corn Cobs may be used as effective adsorbent for treatment pollutant from aqueous solutions.
