Deposition behavior of latex particles in filtration process through glass packed column

Most studies on radionuclide migration in groundwater have focused on the transport of dissolved forms of radionuclides. Colloidal particles, however, can play an important role in the migration. The colloids act as a third phase which is neither a liquid nor a solid phase. This phase can increase the amount of actinides that can migrate in a natural aquifer system. The deposition behavior of colloids from a flowing suspension onto a solid collector surface in filtration process was observed by conducting column experiments with polystyrene latex particles and glass beads packed columns. From the observed particle breakthrough curves, single collector efficiencies were calculated. By comparing the single collector efficiency obtained in the column experiment with the existing approximate expression, the effects of flow velocity on the deposition behavior was discussed
