Our Challenge 

To treat 30,000 acfm of foul odors from the Friskies pet food manufacturing plant, a division of Nestle

Our Solution

A 30,000 acfm Biofiltair system was installed, the in ground concrete reactor is designed with in-plenum secondary pneumatic system spray humidification as well as surface irrigation. A below grade concrete bunker housing was constructed for the fan.

Our Success

Cooling of hot exhaust gases was achieved using a condensing economizer and heat recovered from air streams is used to heat the plant during the winter months. This has been providing excellent odor removal since its commissioning on January 5, 2000.
