This study attempted to utilize bamboo residual, based on pyrolysis at 638°C under oxygen limited condition using the top-lit updraft furnace, to produce bamboo biochar. The characteristics and efficiency of bamboo biochar as low-cost adsorbant for COD removal in municipal wastewater were investigated. Different parameters affecting the adsorption process such as adsorbent dose, contact time and initial COD concentration were studied in batch mode to evaluate the adsorption capacity, kinetics and isotherm models. The maximum COD removal was found to be 81.9 % for 10 g/L of bamboo biochar dose after 4 hour with agitation rate of 150 rpm. Moreover, the experimental data was fitted to Freudich isotherm models and a pseudo-second-order kinetics. The results indicate that bamboo biochar could be employed as low-cost alternative for removing organic pollutant from municipal wastewater. |
