Executive Summary

size distribution, capillary pressure distribution.

  • Generation (proof of concept) of characteristic data of the pore system, e.g. pore
  • Image analysis of 3D-tomography data using VG Studio (expert software).
  • Generation (proof. of concept) of tomography images of filter cakes
  • Selection of compact and needle-shaped particle system
  • Formation of filter cakes with different prose structure due to wetting effects.

The actual state of the project is that the methods have been developed and the concept is investigations.

method, it delivers precise and reproducible surface properties for the scientific (wet) coating with highly hydrophobic silanes. Even though this is a quite time consuming solution. The second one is the modification of the particle surface. For this case, we do a in which we change the wetting properties by changing the ethanol concentration in the shape two scenarios). The first approach is to change the composition of the mother liquid, in particle-particle interaction, we defined two main filtration scenarios (for each particle analyse the overall effect of wettability change in our system, which plays an essential role Particle-particle interaction during the filtration process was another scope of focus.

measurements, thus the solids need to have a certain X-ray adsorption as well as a sample. The material selection also was influenced by the specifications of the Xray filler and plastics. In the case of compact particles, we selected Al2O3 T60/46 alphaalumina we selected Wollastonite, which is widely used in ceramics, friction products, painting a fibrous behaviour when creation the filter cake structure. For the needle-like particles, progress, we applied compact and needle-like particles. The needle-like particles showed In order to analyse the effect of particle shape on the filter cake structure and filtration characteristics.

This study was done on two main particle shapes, which generated different filter cake comprehensive research by producing and interpreting laboratorial and micro-CT data.

Due to the complexity of the parameters affecting the cake filtration process, we do a
