Filtration experiments were conducted using granular beds composed of nearly monosized filter grains and monodispersed suspensions. The experimental data obtained are histories of filtrate quality and pressure drop across the filter bed, from which local filter coefficient and pressure gradient were determined as functions of the specific deposit. The experimental results, together with the results of the analyses of the two limiting situations presented in Part I, were used to develop a general correlation which accounts for the change in filter performance caused by particle deposition.
