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: WebR = Resistance. α = Specific cake resistance. s= Compressibility factor. Filter media: The filter medium acts as a mechanical support for the filter cake and it is responsible for the …

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 … WebA filter cake is formed by the substances that are retained on a filter. Filter aids, such as diatomaceous earth or activated carbon are usually used to form the filter cake. The purpose is to increase flow rate or achieve a smaller micron filtration. ... With increasing layer thickness, the flow resistance of the filter cake increases. After a ... WebSpecific cake resistance c~n be found by a fourth method [3] resting oa the assumption that noc only the filtra- tion pressure, but also the filter cake thickness remains constant … shoes chino hills
