الملخص
This study presents experimental and simulation results for the adsorption of organic pollutants from real municipal wastewater using anthracite-based activated carbon adsorption. This work combines experimental design to investigate adsorption isotherms and kinetics with mathematical modeling to support process analysis and performance prediction for a fixed-bed adsorption column. The results showed that a Sips-type adsorption isotherm model was the most suitable for describing the adsorption curve (R2= 0.9782), with a saturation value of 156.38 mg/g, and the kinetic data of the adsorption of organic pollutants followed a second-order kinetic model (R2= 0.8998). Based on the experimental results, a transfer-dispersion-adsorption model was developed for a fixed-bed adsorption column to simulate the breakthrough curve and evaluate the dynamic performance of the adsorption process. The proposed model was used to predict column efficiency and service life, and to evaluate the impact of key design and operational variables (interfacial flow velocity, adsorbent bed height, and inlet pollutant concentration), providing valuable insights for process design and scaling. The integrated experimental modeling framework demonstrated the feasibility of selecting a fixed-bed adsorber for efficient treatment of real municipal wastewater. The current adsorbent emerged as a promising adsorbent for this type of treatment and performed successfully in simulation scenarios of fixed-bed adsorption units for various wastewater treatment applications.
