Appropriate Use of Deep‐Bed Filtration Models

Abstract

A large number of deep‐bed filtration models have been proposed since the contributions of Iwasaki (1937). The reason behind the development of several deep‐bed filtration models has been the continuing necessity for a better description of the variation of the filtrate quality and the head‐loss development with the filter depth. These models are initially calibrated using observations of the filtrate quality and the head‐loss variation from pilot filter runs, and are then subsequently used to simulate the performance of operational filters. In view of the large number of models of deep‐bed filtration and the existence of conflicting remarks about the uses of many of these, the selection of the most appropriate deep‐bed filtration model and its proper use in the simulation process becomes an important issue. The present study deals with the various aspects of deep‐bed filtration modeling and the appropriate use of deep‐bed filtration models to aid the modeler in achieving simulation objectives.
