Practices to Reduce Ammonia Emissions from Livestock Operations
ثبت نشده
چکیده
filtration may be costly, biofiltration can effectively and inexpensively reduce exhaust odors. Biofiltration costs for a 700-head farrow-to-wean swine facility are estimated at $0.25 per piglet, amortized over a 3-year life of the biofilter. Reductions of ammonia emission at that operation are approximately 74 percent, whereas reductions in both hydrogen sulfide and odor emissions are about 90 percent.

Ammonia Emissions from Agricultural Operations: Livestock
The global abundance of N fertilizer has dramatically increased agricultural productivity. However, when N escapes to the atmosphere as ammonia (NH 3 ) gas, NH 3 loss can cause undesirable effects. In addition to a loss of a valuable resource, it can have negative impacts on air quality, ecosystem productivity, and human health. Animal production is the largest source of NH 3 emission in North ...

متن کاملGas-to-Particle Conversion Process between Ammonia, Acid Gases, and Fine Particles in the Atmosphere
Ammonia emissions are associated with many agricultural operations including animal and poultry operations, waste and wastewater treatment operations, and fertilizer and manure land applications. The fate of ammonia released to atmosphere is affected by interaction with other gases, aerosols, and fine particles. These interactions affect the gas-to-particle conversion. This process alters ammon...
