Investigating the Effect of Packed Structures on Filter Cake Compressibility

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