The relationship between (a) the slope of the aggregation rate, S, and Re1/3Sc when NPs (A = 5.57 × 10−19 J) sized from 95 to 105 nm, moved through mono-disperse packings at velocities of 200 and 500 µm, (b) the coefficient B and the particle concentration, C, when NPs (A = 5.57 × 10−19 J) with different concentrations ranging from 3.6 to 27.4 mg/L traveled through the mono-disperse sphere packing at the pore velocity of 500 µm.
