The effect of concentration on the early stages of deep bed filtration of submicron particles

The removal of mono-dispersed suspensions of 0.46 μm and 0.816 μm particles in the early stages of deep bed filtration was found be higher at a certain range of influent mass concentration. For both equal number concentrations and equal surface area concentrations of mono-dispersed suspensions of 0.46 μm and 0.816 μm particles, the removal of particles of 0.816 μm size was higher during the early stages of filtration than 0.460 μm particles, at lower concentrations. Specific surface coverage was higher for 0.816 μm particles compared to 0.460 μm particles, for influents of these mono-dispersed particles having same number concentrations. However, it was similar for influents of these mono-dispersed particle suspensions, having equal surface area concentration.
