Hydrodynamic parameters from the Michaels and Bolger method

For different initial heights and solids concentration of flocculated calci um carbonate suspensions in the compression range, the variations of the su bsidence rates are discussed in accordance with the Michaels and Bolger met hod. A mathematical model based on the consolidation theory has been applie d to generalize the Michaels and Bolger method, and to discuss the relation ships between the permeability, the effective pressure and the solids conce ntration. In accordance with this model and the experimental results, it is deduced that the relationship between the effective pressure and the solid s concentration differs considerably from that obtained by other methods, w hereas the values of permeability for different solids concentration are cl ose to those deduced by different methods.
