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 ...

WebConstant-Rate Filtration The scale-up of conventional cake filtration uses the basic filtration equation (eq. 4). Solutions of this equation exist for any kind of operation, eg, constant pressure, constant rate, variable pressure—variable rate operations (2). The problems encountered with scale-up in cake filtration are in estabHshing the effective values of the … WebOct 12, 2024 · In Equation 1, ΔP is pressure drop across the filter, µ is viscosity of liquid, α is specific cake resistance, w is weight of dry cake solids per unit volume of filtrate, V volume of filtrate, A is area of filtration, … has more than one overload
