With a large number of techniques particularly used in the treatment of sewage and water, knowledge about flow behavior of permeable agglomerate structures moved in the fluid phase plays an important role in the design of processes and plants. In mechanical separating techniques, this flow behavior has an influence on sedimentation of aggregates in the gravitational field. This knowledge is also necessary for the optimization and specific development of carrier systems for biological process levels with immobilized microorganisms. This paper focuses on the development and verification of a suitable investigation methodology to quantify relevant influencing factors with a view to both the rate of sedimentation of agglomerate structures and flow resistance.
