WebDec 18, 2024 · In cake filtration, important parameters are filter cake resistance and filter medium resistance. Resistance of cake and medium cause pressure drop in the fluid phase and, therefore, influence the filtration setup, such as choice of filter apparatus and suitable pumps as well as integration of filtration into the larger process. Webcosity of filtrate, aav is the average specific cake resistance, W is the mass of cake solid per unit filter area, and Rm is the resistance of filter medium. Taking the inverse of Eq. (1) leads to (2) This equation is used for analysing the experimental method “filtration-permeation” developed by the author [1986].
