A mobile, skid-mounted biofilter was designed and built to determine the kinetics of
ammonia oxidation at a modern2400-sow farrow-to-wean unit. The biofilter system consisted …

Biofilter, dynamic modeling software characterizing contaminant removal via biofiltration,
was used in the preliminary design of a biofilter to treat odorous hydrogen sulfide (H2S) …

Pore volume clogging due to biomass growth from the biodegradation of volatile organic
compounds and other pollutants has significant implications for biofilter operation. As the …

Based on the ideal biofilter model, numerical simulation using lattice Boltzmann method is
carried out to investigate the effect of Darcy number and porosity on removal efficiency of …

BACKGROUND: Biofiltration technology has received much attention due to its
effectiveness, low cost and environment friendly properties. It is used to remove odors …

生物过滤技术因其具有有效性, 低成本和环境友好等优点引起了人们的广泛关注.

Abstract the influence of an adsorbent bed height made of tree bark on ammonia emission
reduction was investigated under two scenarios: for constant mass of adsorbent and for …

The biofilters are the ideal solutions for the biological treatment of air pollutants. However,
there exists strong flow heterogeneity in porous media that degrades the removal efficiency …

Biomass accumulation and its effect on biofilter efficiency were investigated. Ethanol, which
has a high solubility in water and is very biodegradable, was chosen as the model …

Biomass accumulation has been recognized as a limiting factor in the operation of biofilters.
As the biofilm thickens, portions at the base may no longer be exposed to contaminants and …
