Failure of data taken in pilot plant filtration of liquefied coal to fit conventional analysis led to research summarized in this paper. Historically, the effect of migrating fine particles in cake filtration has been ignored in theoretical treatments. In usual development, the total resistance to flow has been broken into cake resistance R/sub c/ and medium resistance R/sub m/. Experiments have only measured the total resistance and have assumed that R/sub m/ remained constant. In this investigation, a filter with seven probes was employed to measure the individual resistances. Medium resistance is found to increase with time and mass of dry cake per unit area due to migration of fine particles into the interestices of a filter medium.
