Although biosorbents are ecofriendly, their potential on large-scale columns has not been assessed yet. This study evaluated the potential of sugarcane bagasse (SB) for the removal of Mn (II) from aqueous media. Firstly, batch experiments were conducted to establish the equilibrium data and predominant adsorption mechanisms. Secondly, a mathematical model was proposed to predict the breakthrough curves in a fixed-bed column. Alternatively, lab- and pilot-scale removal experiments were performed to validate the accuracy of the proposed model. Once the model was validated on both scales, it was employed to predict breakthrough curves for a semi-industrial column under actual conditions of a drinking water treatment plant. Langmuir isotherm (qmax: 2.82 mg/g) and Langmuir kinetic model (R2>0.98 and x2<0.01) reproduced the experimental equilibrium and kinetic behavior. The mathematical model successfully replicated the lab- and pilot-scale breakthrough data (R2>0.95 and x2[removed]es-ESAgricultural residuesFixed-bed columnLow-cost adsorbentManganese removalMathematical modelARTÍCULO10.1016/j.cherd.2023.04.019
