Ammonia emissions from swine feeding operations depend on the housing type; animal
size, age, and type; manuremanagement, storage, and treatment; climatic variables; and …

Sludge is nutrient and mineral rich residue of anaerobic treatment that is often utilized as a
fertilizer. Sludge management is crucial to maintain the function of anaerobic treatment …

Fluxes of atmospheric ammonia‐nitrogen (NH3‐N, where NH3‐N=(14/17) NH3) from an
anaerobic∼ 2.5 ha (1 ha= 10,000 m2) commercial hog waste storage lagoon were …

An accepted definition of antibiotic resistance as presented in 1998 by the Institute of
Medicineis a property of bacteria that confers the capacity to inactivate or exclude antibiotics …

New Zealand dairy and pig farms generate significant amounts of effluents that contain high
concentrations of nutrients such as nitrogen (N), potassium (K), and phosphorus (P), and …

Lagoon sludge, a byproduct of swine operations in the Southeast United States, poses a
management challenge due to its high mineral and metal content. Composting is a low-cost …

Concentrated animal production may represent a significant source for ammonia emissions
to the environment. Most concentrated animal production systems use anaerobic or …

A mathematical model to estimate ammonia emission from anaerobic swine lagoons was
developed based on theclassical twofilm theory. Inputs to the model are wind speed and …

This study determined the water quality improvements in swine lagoons by an innovative
swine manure treatment system operating at full-scale during five pig production cycles. The …

For removal of phosphorus (P) from swine liquid manure before land application, we
developed a treatment process that produces low P effluents and a valuable P by‐product …
