Abstract:
The implicit backward Euler finite difference scheme was used to develop and numerically solve a mathematical model for a fixed-bed adsorption column. MATLAB R2012a was used to implement the simulations. The work systematically assessed both the design and operational characteristics of the column for the treatment of industrial wastewater and successfully produced the corresponding breakthrough curve. Results from the parametric study indicated that a decrease in bed porosity shortens the solute residence time within the column, thereby improving the adsorption rate. In addition, smaller particle sizes were found to reduce the breakthrough time, whereas higher flow rates led to a more rapid increase in the adsorbate concentration ratio. These behaviors are in close agreement with trends reported in previous studies on similar adsorption processes. The findings demonstrate that the proposed model accurately represents the performance of a fixed-bed adsorption column and is suitable for analyzing its behavior under isothermal conditions.
