Odor Control + Get Alerts

The Whisper Biofilter is a one- or two-stage odor control unit that allows for optimal odor removal via variably controlled beds that provide the proper biological environment for H2S and associated sulfur compound removal. Units are designed for quiet operation with high odor removal.

How it works
Whisper Biofilters are packed with Bioglas media. The Bioglas media is manufactured in the U.S. 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, corrosion-resistant fan, which provides quiet operation, and then through an air distribution plate to provide even distribution throughout the media.

The Whisper Biofilter removes 99 percent of incoming H2S and effectively reduces other common odor compounds. The Whisper Biofilter can treat airflows up to 1,100 cfm, and H2S concentrations above 100 ppm. The units are designed and fabricated in the U.S. with skid-mounted controls for easy installation and operation.
