Abstract
In the present study, we treat the dirty (small) and the adsorbing (large) particles as charged and anti-charged spheres and investigate the behavior of these particles under the gravity field by means of Brownian dynamics simulations. We here have discussed mainly the dependence of the adsorption rate on the particle diameter ratio, the volumetric fraction of large particles and the input amount of large particles. The large particles adsorb much more small particles, but the total number of small particles adsorbed by the large particles is larger for large particles with smaller diameter. Hence it is seen that putting a numerous number of adsorbing particles with smaller diameter into water is more effective for removing the suspended substances or dirty particles. Even if the input amount of large particles is increased, an adsorption performance cannot significantly be improved; the number of inefficient large particles that do not contribute to the adsorption performance increases. From these results, we understand that there is an optimal input amount of adsorption agents from a commercial point of view.
