aerated lagoons is usually less effective than in facultative lagoons because of shorter detention times. Nitrification of ammonia can occur in aerated lagoons or if the system is specifically designed for that purpose. Phosphorus removal is also less effective than in facultative lagoons because of more stable pH and alkalinity conditions.

CH4 AND N2O EMISSIONS FROM LIVESTOCK MANURE

caps for lagoons or tanks where manure is kept. This recovered methane is often flared or used as a fuel in a boiler, heater, or an engine-generator. Nitrous Oxide Generation Production of N2O during storage and treatment of animal wastes can occur via combined nitrification-denitrification of nitrogen contained in the wastes.
