Odorgon: Overhead Spray System to Neutralize Odors

Reprinted, with permission, from the proceedings of: Mitigating Air Emissions From Animal Feeding Operations Conference.

This Technology is Applicable To:

Species: Poultry, Dairy, Beef, Swine
Use Area: Animal Housing
Technology Category: Chemical Amendment
Air Mitigated Pollutants: Ammonia, Hydrogen Sulfide, Odors

System Summary

Odorgon is a water based formulation that is applied in confined animal feeding operations through a high pressure mist system. Odorgon is sprayed on an automated timer basis from the ceilings through high pressure nylon lines and nozzles to neutralize malodors.

Applicability and Mitigating Mechanism

  • Unique class of cationic surfactants
  • Atomized solution sprayed at 600 psi
  • Buffer resulting in non volatile organic salts
  • Greatly reduces ammonia & hydrogen sulfide
  • Creates better environment for animals to thrive in resulting in lower mortality, less culls and less days to finish.
  • Better conditions for workers/employees
  • Mitigates neighbor/social issues


  • Water based, subject to freezing
  • Summer use may be curtailed in

open buildings during windy conditions


Equipment cost for a 42 by 200 foot finishing building with all components installed is approximately $4900. Annual usage for this facility would average $2100 of Odorgon concentrate or .73 per animal unit but could vary with region/climate. Nursery cost for swine is .19 per animal unit. Odorgon is mixed with water at a rate of 50 parts water to 1 part concentrate resulting in a cost of $1.50 per gallon diluted. Cost also varies based on building dimensions and desired results.
