For media filtration, why is it important to have a particle size distribution of the suspended solids?
Different types of media filters produce different porosity or interstices sizes. Media filters work best when the particle size distribution is normal. That means there are particles of various sizes in various concentrations. In this way, the particles themselves can enhance removal and increase the efficiency of the media filter. If the particle size distribution shows that many of the particles are fine and make up most of the concentration, a media filter may not effectively remove those particles.
