Odor Reduction Study

Elevated levels of hydrogen sulfide (H2S) created health problems for animals at a concentrated animal feeding operation (CAFO). Reuse of the effluent in flush gutters also contributed to high odor and nutrient loads within the facility.

Challenges: 

Elevated levels of hydrogen sulfide (H2S) created health problems for animals at this swine production facility.  

The Approach Taken: 

The owner of the facility, in conjunction with assistance from Colorado State University (CSU), installed The BiO2 Solution™ system to control ammonia and hydrogen sulfide levels. This facility has multiple production units, each having its own lagoon system.  A single lagoon at one of the units, designated as Lagoon “A”, was not treated and was used as the control site. A single lagoon at a second unit, designated as Lagoon “E”, was treated with the BiO2 Solution™ and utilized as the testing site.

 

Results: 

Using Gerome meters to determine hydrogen sulfide (H2S) levels, researchers at CSU were able to determine that up to 97% of the odor producing compounds had been removed.
