Abstract

Scarcity water has become one of the biggest problems facing the world in general and developing countries in particular.Therefore, the search for alternative and non-traditional water sources was the most important goal of the mission. In addition to that, the use of inexpensive and economical materials so that an alternative water source can be provided through wastewater treatment. Industrial contaminated with dyes. Four agricultural wastes, sugarcane bagasse, rice straw, cotton stalk and corn stalk were experienced as low-cost lignocellulosic materials for their ability to adsorb reactive red dye from its contaminated solutions. Batch adsorption technology was carried out in order to analyse sorption behaviour of dye-adsorbent systems at different wastes, initial dye concentration and solution pH. The acid pH treatment was detected to significantly enhance the adsorption efficiency of used lignocellulisic wastes to maximum removal efficiency (96 %). Bio-reactor technology was applied as up scaling experiments using sugarcane bagasse wastes (the best adsorbent under batch experiments) with different adsorbent dosage and flow rates. The maximum removal efficiency (89.65 %) was recorded by 448 g of SCB waste, hydraulic retention time of 24 h and 12.6 l/h flow rate. The SEM characterization illustrated that accumulation of dye molecules onto lignocellulosic structure. Also, elemental analyses by EDAX instrument confirmed absorption technology. Thus, the sugarcane bagasse wastes can be applied as low-cost and environmental safe absorbent for RR dye removal from its contaminated wastewater and introducing non-traditional water resource
