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. As an interaction potential between these charged particles, we have employed the electrical interaction energy based on the electrical double layers formed around the particles. Although putting a numerous number of large particles enhances the adsorption rate, the number of inefficient large particles that do not contribute to the adsorption performance increases. If it is necessary to remove the dirty particles during a short period, adsorbing particles with larger diameter may be used. If it is desirable to obtain a significant adsorption performance even if a long time period is necessitated, adsorbing particles with smaller diameter may be adopted.
