Filtration and Particle Discrete Data (glass beads < 160 µm) for 'Project Development of multivariant structure and process models for filter cakes, combining experimental methods of process engineering with digital computer based methods'

Abstract

This dataset contains primary experimental data investigating the filtration behavior and particulate properties of glass particles, spherical, < 160 µm. The data was generated through separation tests conducted in accordance with the VDI 2762 guideline (cake-forming filtration). The study aims to correlate particle morphology with specific filter cake resistance within a viscous medium. Soda-lime glass (SiO2, 2.55 g/cm³) from Sigmund Lindner GmbH, was used as the disperse phase. To ensure a defined particle size distribution, the material was pre-classified to a target range of 70 to 160 µm using a Nisshin Turbo Classifier TC-15M fine air classifier. The continuous medium consisted of a binary water-glycerin mixture: Glycerin content: 24 mass percent (wt%) Additive: 25 mM potassium iodide (KI). Both chemicals were sourced in analytical grade from Carl Roth GmbH + Co. KG. Complementary 3D-characterization data, including CT scans (Computed Tomography) and segmented individual particle data, are archived in the "Parrot" database of the TU Bergakademie Freiberg (https://parrot.tu-freiberg.de/).
