Specific cake resistance in filtration
WebW = Mass of filter cake. R = 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 collection of solids. Minimum cake thickness of discharge for different types of filter is presented in Table 7.1. WebThe filtration area of the unit is 0.15 ft2 and the slurry concentration of solids per volume of filtrate is 10.124 lbm/ft3. Calculate the specific cake resistance and filter medium resistance. Viscosity of the fluid is 6.72 × 10-4 lbm/ft-s. a. Calculate the specific cake resistance, α, in ft/lbm b.

WebThe average specific cake resistance from the filtration period calculated with the mass fraction of sediment and that from the permeation period coincide very well. These values also coincide well with the former average specific resistances during permeation within the experimental error limits.
WebFrom interpretation of test data, a parameter called the specific cake resistance, which directly reflects the efficiency of a given diverting agent, can be computed. This parameter is related to cake and particle properties so that it can render a means of scaling up test data to field situations. WebSep 1, 2001 · The specific resistance can then be expressed as a function of particle ( (A4) shape, mean particle size, polydispersity, cake porosity and = 1- 6 n, expl 3]n d,, + In^ …
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 … WebAfter establishment of the theory of cake filtration by Ruth [1946], it has been considered that cake filtration is performed by filter cake and the role of filter medium is supporting the filter cake only. Grace [1953] stated that the filter medium resistance could be neglected when it is less than 1% of final resistance of filter cake. But ...
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.
Web1 day ago · In addition, filter cake thickness plays a vital role in fluid permeance. When particles and chemicals substantially deposit on the filtration cake, the cake thickness increases, but too thick filter cake is likely to increase drilling resistance and torque, even leading to differential pressure sticking. christian mccaffrey thursday nWebApr 15, 2024 · Figure 10 illustrates the effect of integrating a 3D printed (3DP) turbulence promoter into a filtration cell on resistance values. Reversible resistance was identified as a key component of the resistance, implying that membrane fouling occurred based on the cake layer model, which is more easily removable than irreversible fouling. christian mccaffrey to chiefsWebJun 1, 2013 · The specific cake resistance to filtration was found to vary between 1 × 109and 1 × 1011 m kg−1, depending on the applied pressure, and the corresponding filter cake volume concentrations were between 0.42 and 0.54 (v/v). christian mccaffrey to buffaloWeb3 rows · Jun 20, 2024 · Resistivity of filter cakes depends on the conditions of formation of which the pressure is the ...
