Abstract
Deep bed filtration has been used successfully in the metallurgical industry for the filtration of melts prior to casting. At the high temperatures which exist in melt filtration, some of the contaminants may actually be liquid, so that the system resembles a dilute emulsion. A solids filtration model developed by Apelian and Mutharasan (1980) is experimentally tested for its application to low-temperature depth filtration of a dilute emulsion. The fundamental parameters characterizing filtration rate and filter capacity are tested for their dependence on fluid velocity, filter grain diameter and the wettability of the filter media. It was found that the model does characterize the operation of the filtration system. The kinetic constant, which represents the initial rate of filtration, was found to increase with velocity and had an average dependence on grain diameter of d exp --2.5 . The rate of increase of the constant with velocity was greater for the system where the droplets did not wet the filter grain. The filter capacity increased with velocity for the nonwetted filter grains, but decrease d with velocity for the wetted case. 23 ref.--AA.
