Why Capture Ammonia Released from Animal Manure?

Excessive emissions of ammonia (NH3 ) from animal manure negatively impact the environment with potential to pollute air, soil and water, and produce malodors. The objective of this study was to assess NH3 mitigation from liquid dairy manure (LM) using tubular acid-filled gas-permeable membranes (GPM) in laboratory experiments; and, to evaluate the possibility of scaling up the NH3 mitigation system for use on AFOs.…
