Oxidation kinetics of phenolic and indolic compounds by ozone: applications to synthetic and real swine manure slurry
January 1, 2002By Jerry J. Wu
In this study, an oxidation model combining the mass transfer of ozone and ozonation kinetics was developed to predict the degradation of several phenolic and indolic compounds in a semi-batch...
Summertime concentrations and emissions of hydrogen sulfide at a mechanically ventilated swine finishing building
January 1, 2002
Hydrogen sulfide (H2S) concentration and emission at a modern mechanically ventilated swine finishing building with a deep pit were continuously measured for three summer months. The building is...
Simulating Swine Manure Transport in Soils Using the Mobile-Immobile Contaminant Transport Model
January 1, 2002By Victor B. Ella
Modeling swine manure transport is an important initial step not only in understanding the behavior of this potential contaminant in the subsurface environment but also in providing a basis for...
Swine Wastewater Treatment in an Integrated System of Anaerobic Digestion and Duckweed Nutrient Removal
January 1, 2002By J. Cheng
Organics destruction and nutrient uptake in an integrated pilot system of anaerobic digestion and duckweed nutrient removal for swine wastewater treatment were monitored under field conditions. Raw...
Solid-liquid separation of flushed swine manure with PAM: effect of wastewater strength
January 1, 2002By Matias B. Vanotti
Organic polymers are useful to increase separation of suspended solids and reduced carbon compounds from liquid swine manure. Along with the solids, there is a capture of the nutrients associated...
Precipitation of swine and cattle manure phosphorous using limestone dust
January 1, 2002
The effectiveness of SPS and PULPRO, fine limestone dusts, in precipitating swine and dairy manure phosphorous (P) was determined in the laboratory. Both manures were sieved before being treated with...
Quality-assured measurements of animal building emissions: Particulate matter concentrations
January 1, 2002By Heber A
Federally funded, multistate field studies were initiated in 2002 to measure emissions of particulate matter (PM) < 10 mu m (PM10) and total suspended particulate (TSP), ammonia, hydrogen sulfide,...
Nutrient recovery from swine lagoon water by Spirodela punctata
January 1, 2002
Spirodela punctata 7776, the best duckweed strain in total protein production selected from in vitro screening experiments with synthetic swine lagoon water medium was examined for N and P recovery....
Nutrient Transport as Affected by Rate of Overland Flow
January 1, 2002By John E. Gilley
Little information is currently available concerning the effects of varying flow rate on nutrient transport by overland flow. The objective of this study was to measure the effects of overland flow...
Effects of temperature, soil water status, and soil type on swine slurry nitrogen transformations
January 1, 2002
Manure N dynamics are affected by manure characteristics, soil factors, and environmental conditions. An incubation experiment was conducted to assess the relationship of these factors. The effects...
