Biofilm Growth-Percolation Models and Channeling in Biofilter Clogging
Biomass accumulation is a load-limiting factor in the operation of biofilters used for air pollution control. As the biofilm thickens, portions at the base are no longer exposed to contaminants and oxygen and, thus, provide no treatment. Smaller pores are filled with biomass so that air no longer flows into them. As airflow paths are restricted, air may be prevented from reaching some pores even ...

Wet scrubbers air pollution control devices
Wet scrubbers are effective air pollution control devices used to remove particulates and/or harmful gases from industrial waste streams. Wet scrubbers operate by introducing a dirty gas stream into the scrubbing liquid (usually water + neutralizing liquid). Particles or gases are collected in the scrubbing liquid. Wet scrubbers are often the most suitable air pollution control equipment for ...
