Understanding the limits of H2S degrading biotrickling filters using a differential biotrickling filter
The removal of H2S in high performance biotrickling filters was investigated using a differential biotrickling filter. The differential biotrickling filter was designed to reach high gas velocities through a minature packed bed, in this case a single 4-cm open-pore polyurethane foam cube. External mass transfer was limiting below air velocities of 3000–4000 m h−1, with possible other parameters...
متن کاملCo-treatment of H2S and toluene in a biotrickling filter
Biological treatment is an emerging technology for the treatment of publicly owned treatment works (POTWs) off-gases. Most of POTWs off-gases contain H2S and a wide range of volatile organic compounds (VOCs). Since co-treatment of odors and VOCs in biotrickling filters is a relatively unexplored area, the simultaneous biotreatment of H2S and toluene (as the model VOC) was investigated. The expe...

regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
Biomass control in waste air biotrickling filters by protozoan predation.
Two protozoan species as well as an uncharacterized protozoan consortium were added to a toluene-degrading biotrickling filter to investigate protozoan predation as a means of biomass control. Wet biomass formation in 23.6-L reactors over a 77-day period was reduced from 13.875 kg in a control biotrickling filter to 11.795 kg in a biotrickling filter enriched with protozoa. The average toluene ...
