EVOQUA INTRODUCES NEW WHISPER™ BIOFILTER SYSTEM FOR QUIET AND EFFECTIVE ODOR CONTROL IN RESIDENTIAL LOCATIONS

Pittsburgh, PA - March 23, 2016

Evoqua Water Technologies today announced the introduction of the WHISPER™ Biofilter System for quiet and effective odor control in residential locations. The new WHISPER™ Biofilter System provides 99% hydrogen sulfide removal with quiet operation.

The WHISPER Biofilter is a one or two stage odor control unit which can treat airflows up to 1,100 cfm and H2S concentrations above 100 ppm. Its proprietary rotating irrigation system provides uniform water and nutrient distribution for optimal biomass growth. A variable speed fan ensures quiet operation.

WHISPER Biofilters are packed with non-degradable Bioglas™ Media, manufactured from acid-resistant recycled glass, for long-lasting performance.

Turn-key full service units are available on a monthly rental basis to reduce capital investment. Evoqua has six regional service centers with experienced personnel to ensure quick and effective odor control.
