Biofiltration is continuing to gain popularity as a viable odor control alternative because of its overall effectiveness and ease of operation. Typical operations procedures consist primarily of biofilter bed headloss monitoring and bed humidification. This paper compares and contrasts humidification options for biofilters.

Humidification to maintain biofiltration is split into two main types: surface or bed humidification, and in-duct humidification. Bed humidification is needed primarily to replace evaporative losses from the biofilter bed surface. The in-duct humidification is needed to maintain moisture throughout the bed.

In-duct humidification options include, but are not limited to, spray or mist nozzle injection, steam injection, absorption tower humidification, and mist tower humidification.

In northern climates where odor control must be maintained during potential freezing conditions, supplemental heat can be added to maintain performance. In these installations, it is possible to couple the in-duct humidification system with a system to add supplemental heat.
