摘要：

Treatment of radioactive waste at the Hanford site is dependent upon dead end filtration to prepare feed for ion exchange. Recent testing has indicated that the filter media that will be deployed for this treatment process is susceptible to depth fouling. A model was developed to understand the transition from pore fouling to cake filtration to provide insight into the planned operations of this facility. These results indicate that an initial transition takes place during which the filter is depth fouled. However, after the majority of the pores have been plugged the filter flux is governed by cake filtration on the surface of the fouled filter.
