TL;DR: In this paper, the air-filled pore space was measured with an air pycnometer and also calculated from mass balance and CT data, showing that compaction-induced reduction in the cross-sectional area of vertical, arterial macropores and in the volume of marginal pores branching from these vertical pores.
Journal ArticleDOI
Pressure drop in biofilters as related to dust and biomass accumulation
TL;DR: In this paper, the relationship between filter pressure drop and accumulation of DBM in the filter was examined using a commercial available material: light expanded clay aggregates (Leca®) consisting of porous rounded aggregates with similar shape.
Journal ArticleDOI
A comparative study of mass transfer coefficients of reduced volatile sulfur compounds for biotrickling filter packing materials
TL;DR: In this paper, a study of overall mass transfer coefficients of volatile sulfur compounds for packing materials potentially used for biotrickling filters is presented, where the authors use online PTR-MS experiments of breakthrough curves, combined with a developed mass transfer model.
Journal ArticleDOI
Air–water mass transfer of sparingly soluble odorous compounds in granular biofilter media
TL;DR: In this paper, the authors investigated the impact of particle size, compound solubility, and contaminant chemical properties on the overall volumetric mass transfer coefficient based on direct measurements of volatile, sparingly soluble, odorous organic compounds in granular media.
Journal ArticleDOI
Relating Gas Dispersion in Porous Media to Medium Tortuosity and Anisotropy Ratio
TL;DR: In this article, a set of three different porous materials with similar particle size, as a func- tion of material tortuosity and anisotropy ratio, was investigated, where the materials were packed with different spatial orientations of the individual particles.
