HOW DRY SCRUBBERS WORK

BIOREM provides dry scrubbers as stand-alone units or as a polishing stage following other pre-treatment technologies. Due to the relatively small bed volumes, media changeouts are quick and require little labor.

BIOREM develops custom blends of adsorbents to match the requirements of the specific application and types of compounds being targeted.

Virgin activated carbon is the most popular dry scrubber media type.

Sourced from coconut shells char or bitumous coal, it is steam activated to produce exceptionally high surface area. The high surface area results in the adsorption of high boiling point volatile organic compounds onto the surface of the media.

Adsorption can be described as enhanced liquefaction due to London dispersion forces. BIOREM engineers are able to predict the adsorption capacity of activated carbon for any volatile organic compound using the Polanyi/Dubinin Potential Theory of Physical Adsorption, including multicompound interactions and the effect of relative humidity.
