Granular activated carbon (GAC) filtration is a very important treatment unit operation in drinking water production processes. GAC filtration is widely used for its filtration and adsorption capabilities as a barrier for undesired macro and micro-pollutants. GAC filtration consists of two ascending procedures: filtration procedure, capturing the impurities from the water, in conjunction with a backwash procedure, flushing these impurities out of the system. The prediction of the bed expansion of GAC is complex since the particles are non-spherical, porous and polydisperse. It is complicated to find GAC particle properties such as the wet density, wet mass and the minimum fluidisation porosity. To be able to predict the porosity these values must be known.

This data set contains numerical data of fluidisation experiments for various flow rates, water temperatures for nine different GAC types. In addition, a large data-set is shared with drying log (evaporation) values. Also, photographic and video material as well as morphological measurements (Camsizer, ImageJ, sieve and microscope) are provided.
