Documentation of the data
datacite.description.TechnicalInfo

The repository contains the filtration logs as TDMS files, which can be processed with LabVIEW or common Python/MATLAB plugins. The filtration test rig scheme is enclosed in the dataset. The Video data is recorded in .avi format with a resolution of 1024x1024 pixels. A field of view (FOV) of 5x5 mm was used to capture the particles. The Sympatec measurement range M6 with the cuvette with a gap size of 0.50 mm was used. Characteristics such as projection-area-based size distributions and shape factors (sphericity, aspect ratio, and convexity) can be extracted. See readme.txt for further information.

Description of the data
datacite.resourceType

The dataset is divided into two main categories: Filtration Data (VDI 2762), Measurement protocols of cake formation under varying filtration pressures. The raw data includes synchronized channels for filtrate mass, time, temperature, and pressure. These parameters allow for the determination of the specific cake resistance and filter medium resistance. Dynamic Image Analysis (Sympatec QICPIC): High-resolution particle characterization data. Dynamic Image Analysis was performed using the Sympatec WINDOX 5 software suite, ensuring compliance with ISO 13322-2 for automated image analysis. See readme.txt for further information.

Abstract of the dataset
dc.description.abstract

This dataset contains primary experimental data investigating the filtration behavior and particulate properties of quartz particles. 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. Quartz (SiO2, 2.7 g/cm³) from Strobel Quarzsand GmbH, product name BCS201, was used as the disperse phase. To ensure a defined particle size distribution, the material was pre-classified to a target range of 50 to 200 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/).

Project abstract
opara.project.description

A central question in the design of filtration processes still is: what are the filtration properties of a given particle system? The state of the art, like the established Carman-Kozeny-equation, is not capable to calculate with technically sufficient accuracy the specific cake resistance or the capillary pressure distribution form a given particle size distribution. That is why there are still several empirical correlations in this field, which are only valid in a small field of definition and which therefore cannot be seen as universally valid. In the context of process simulation it is therefore not possible to implement the step from particle properties to the properties of the corresponding pore system, i.e. the corresponding filter cake. The aim of this project is the correlation of the distribution of multi-dimensional particle properties, where both the particle size and the particle shape are regarded as distributed properties, with the distribution of properties of the 3D morphology of the filter cake built up from these particles. Tortuosity and pore size are examples for distributed cake properties. For this purpose, methods from experimental process engineering are combined with digital computer-based methods. Analytical particle characterization as well as tomographic image data of the investigated particle systems and of the resulting filter cake structures serve as the basis for characterizing the particle properties and the 3D morphology of two- or three-phase filter cake structures using parametric stochastic models. On the one hand, the multi-dimensional distribution of particle property vectors (e.g. particle size and shape characteristics) and the properties of the resulting multi-phase filter cake system are modeled with parametric copula approaches. On the other hand, parametric 3D structure models are calibrated, which can then generate virtual 3D particles or multi-phase filter cake structures, so-called digital twins, that are equivalent in a statistical sense to the tomographic image data. Both copula models and 3D structure models are described with only a few parameters, which enables efficient characterization of the underlying particle and pore systems. Then regression techniques are used to determine transfer functions, which map parameters of the models describing the particle systems onto the model parameters describing the filter cake structure. In this way, it will become possible to predict the process behavior (e.g. de-watering, cake washing, dispersion) of a filter cake, solely from the knowledge of the underlying (multivariate) probability distribution of multi-dimensional particle properties.
