Abstract

Predictive model equations of a “fixed-bed adsorption column” packed with particles and the Langmuir adsorption isotherm equilibrium model were considered. A Computational Fluid Dynamic (CFD) simulation using COMSOL Multiphysics sofware of the adsorption column for the removal of iron from groundwater was carried out. “The results were presented in a line graph. The effect of particle size on the breakthrough curve was investigated for particle sizes of 0.001m, 0.002m, 0.003m and 0.004m. Simulated results showed that as the particle size increases the adsorption capacity of the bed decreases and about 28 days operative performance of the bed could be achieved for a bed weight of 1500kg and particle size of 0.001m”. Predicted results were compared with results presented by Ruthven, 1984 and World Health Organization standards and the results were very acceptable.
