Cake resistance formula

WebAs the pressure increased, the cake resistance was expected to increase as well. • Due to the buildup of cake on the filter, hindering flow. The data observed showed a trend that as the pressure increased, the cake resistance tended to rise as well. Resistance by the filter generally increased as pressure rose WebIn Eq. (12) p m and α m change with time (decrease) during the swelling. Eq. (12) differs the present paper from important works on the filter cake behavior after the filtration pressure release ...

WebThe membrane has a surface area of 17.3 cm 2; the membrane resistance and thickness are not known. The milk contains 4.3 kg/m 3 solids and has a viscosity of 0.001 Pa-s. We previously filtered this milk at an applied pressure drop of 20 psi and the following data was collected: Time (hr) 0.5. 1.0. WebIt is logical to assume that the resistance of the cake is proportional to its thickness L. The proportionality constant r (m −2) is called ‘specific cake resistance’. The resistance of the filter medium may be seen as the resistance of an additional fictitious cake thickness, L f. Substituting in Eq. (8.3), we obtain:
