How To Select and Size Filters

The selection and sizing of filters depends on the characteristics of the type of filter and the feed slurry. In addition, the rate functions of cake formation, cake washing and cake dewatering must be determined in order to design the filter station on the basis of desired performance. This chapter discusses the applied theory used to determine the rate functions and illustrates how to incorporate these into the filter cycle to obtain the required objectives. This also permits the sizing of the filter and auxiliaries as well as the selection of the proper type of filter.
