Investigation of filter cake characteristics regarding particle shape and wettability

M. Brockmann*, T. Lei├čner, U. A. Peuker, Technical University Bergakademie Freiberg, Germany

The filtration of cubical and needle-like particles plays a significant role in pharmaceutical and industrial applications. This research project focusses on two particulate materials different in particle shape and wettability in order to investigate the effect of particle features on filter cake characteristics.

An alumina (Al2O3) powder is used as representation for cubical particles. As needle-like particulate material, wollastonite (CaSiO3) was used. To investigate the influence of particle wettability on the filter cake structure, we hydrophobized the particles. The filtration experiments were performed using solutions of different ethanol vol.-% to analyse the influence of wettability on filter cake characteristics. It was observed that...
