“…However, recent research conducted by Kuhn et al 24 effectively showed that fitting the filtration curve nonlinearly to a root function is more precise both in terms of execution and results. Thus, the change in filtrate volume over time is described as:

true V = \sqrt{\frac{2 Δ p A^{2}}{η α_{normalK} k} t + {(\frac{R_{normalM} A}{α_{normalK} k})}^{2}} - \frac{R_{normalM} A}{α_{normalK} k}

Packed beds used in absorption columns have shown to increase filter cake permeability during specific filtration processes. Their effect on filter cake compressibility is evaluated. Different model systems are characterized using dead‐end filtration equipment and a modified universal testing machine. Compression experiments are conducted with different packings to assess the systems' response to compressive stress. The structural support of the packings reduces filter cake compressibility for the tested configurations. The extent of this effect depends on packing type, applied pressure, and material compressibility. These results help to understand the advantages of using packed beds as aids for filtration processes and represent a step further in designing tailored packings.

Specific parameters of cake filtration, such as the filter cake and filter medium resistances, can be determined using the pressurized housing cell standardized in the guideline VDI 2762 by measuring the filtrate mass on a laboratory scale. For reproducible measurements and an exact detection of the filtration start, an improved test setup is presented and compared with a standard setup according to the guideline VDI 2762. On the basis of measurements without and with a particle system to be filtered, it is shown that the characteristic nonlinear course at the beginning of each filtration, which can be seen in the t/V-V diagram, is influenced by the used measuring equipment.
