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

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.
