Abstract:
The paper reviews the effect of particle size distribution and pore size
distribution on granular bed filter and crossflow microfiltration performance. The
experimental results of the granular bed filter with pollen particles in suspension
showed that the presence of large particles improved the filter efficiency of
smaller particles in suspension. Microfiltration results with bi and tri-modal latex
suspensions showed that the permeate flux and the quality were significantly
affected by the particle size and its distribution, especially when the particle size
was smaller than the pore size of the membrane. The mathematical model simulation
results of granular bed filtration show that media pore size distribution is
an important parameter of filtration for the particle removal and pressure drop
across the filter.
