A new procedure for determining specific filter cake resistance from filtration data

A new procedure has been developed for the determination of specific filter cake resistance from experimental filtration data. Unlike the conventional procedure which treats constant-press Lire filtration data through the t/V v.s V plot and yields a single value of the average specific cake resistance (alpha(av)) from a given experiment, this new procedure allows the establishment of the relationship Of alpha(av) vs. the cake compressive stress (p(s)) over a range of p(s) values. Results from the new procedures were compared with those obtained from the procedure based on the t/V vs. V plot as well as those from compression-permeability (C-P) measure measurements. Discussions Oil the possible improvement of the new procedure are also presented. (c) 2006 Elsevier Ltd. All rights reserved.
