    Activated carbon (AC) is an adsorbent widely used in water treatment, however, it has some technical disadvantages, such as its high cost and difficulty to recover. To overcome these drawbacks, AC particles have been encapsulated within a polymeric support, mainly alginate-based. The use of these biological macromolecules results in composites with lower-cost, superior mechanical properties, and higher number of functional groups, advantages that have been attracted the attention of the scientific community. Four adsorbents, activated carbon (AC), alginate (AL), activated carbon/ alginate (AC/AL) and activated carbon, alginate, and bentonite (AC/AL/Bt) were proposed in this work to remove Methylene Blue (MB). The process parameters such as adsorbent diameter, column height, column diameter, mass composition and initial concentration of MB are investigated based on the dynamic simulation results using Aspen Adsorption V11 simulation software. The relationship between the five process parameters and saturation time were studied. Based on the optimized simulation results, AC/AL/Bt obtained the highest saturation time (63020 s) in a Fixed-bed column to treat water contaminated with 25 mg/L methylene blue concentration. Additionally, the suitable process parameters magnitudes are adsorbent particle, column height, column diameter, and mass composition of 1 mm, 2 m, 0.05 m, and 30% AC/ 15% AL/ 55% Bt, respectively. The outcomes of this study suggest the potential of AC/AL/Bt composite for cationic dye removal.
