Hydraulic Conditions During Liquid Flow Through Sorbent Materials

This contribution presents an experimental analysis of the static
characteristics of selected sorbent materials under liquid flow conditions.
The study focuses on cenospheres—lightweight microspherical particles formed
as a by-product of coal combustion—tested in several distinct particle size
fractions, as well as on a ceramic granulate of defined fraction. A dedicated
experimental setup was constructed, featuring a modular filtration unit designed
to ensure the stable placement of the sorbent material. The sorbent was secured
within the filtration chamber using geotextile membranes. During the tests, flow
rates and the corresponding pressure drops were systematically measured for
each material fraction. Based on the collected data, characteristic curves showing
pressure drop as a function of flow rate were plotted. The results enable
a comparison of the hydraulic resistance of the individual sorbents depending on
their size fractions. The measured data will further support the selection
of optimal sorbent materials for filtration applications, with an emphasis on
minimizing pressure losses and maximizing sorption capacity—aiming at
the efficient design of energy-saving filtration systems.
