Correlation of C-P cell and filtration test data using a new test cell

Abstract

In this paper, two types of material forming filter cakes with different compressibility and compactness, namely CaCO3 and Kaolin were examined in a new test cell. Our measurements in the new test cell showed that C-P test data could predict reasonably well the actual filtration process. Taking into account the effect of side-wall friction, there were about 2-15 and 1-16% differences in average cake specific resistance for CaCO3-H2O and Kaolin-H2O system, respectively, between the C-P prediction and the actual filtration process in the pressure range of 1-8 barg. In terms of average cake porosity, the predicted values are found to agree within 3-4% for CaCO3 cake and 4-18% for Kaolin cake with those determined from actual filtration test. © 2002 Elsevier Science B.V.
