The WHISPER® Biofilter is a one or two stage odor control unit that allows for optimal odor removal via variably controlled bed(s) that provide the proper biological environment for H2S and associated sulfur compound removal. Units are designed for quiet operation with high odor removal.
WHISPER Biofilters are packed with Bioglas® media. The Bioglas media is manufactured in the USA from acid resistant recycled glass material as the substrate for the biomass. Each media bed is intermittently irrigated with water and nutrients to provide optimal conditions for the biomass growth. The unique irrigation system uses a rotating arm to provide the most uniform water and nutrient distribution available. The incoming air is passed into the unit by a variable speed controlled corrosion resistant fan, which provides quiet operation, and then through an air distribution plate to provide even distribution throughout the media.
