The effectiveness of aerobes used as manure additives for swine manure odor control
January 1, 2000By JUN ZHU
The objective was to examine the growth of aerobic bacteria in swine manure when used as manure additives for odor control. Hydrogen peroxide was used as an oxygen provider added to the test manure...
Constructed Wetlands as Remediation Tools for Shallow Groundwater Contaminated by Swine Lagoon Seepage
January 1, 2000By Michael R. Burchell II
Constructed wetlands have been implemented as treatment systems for wastewater. Wetlands may remove nutrients and sediment through biogeochemical functions such as adsorption, nitrification,...

Impact of feeders and drinker devices on pig performance, water use, and manure volume
January 1, 2000By Michael C. Brumm
Objective: To determine the impact of feeder and drinker designs on pig performance, water use, and manure volume. Methods: Experiment One compared a wet/dry feeder to a dry feeder with...
Changes in Swine Manure Solids During Storage May Affect Separation Efficiency
January 1, 2000By JUN ZHU
A laboratory study revealed the dynamic changes of solids in swine manure during storage in order to determine the best time for efficient solid-liquid separation treatment. Data showed that...
Swine wastewater treatment in a two stage sequencing batch reactor using real-time control
January 1, 2000By K. V. Lo
A laboratory scale two-stage sequencing batch reactor (TSSBR) was used to study the effectiveness of pH as a real-time control parameter in swine wastewater treatment. A Ringlace media was inserted...
Nitrification treatment of swine wastewater with acclimated nitrifying sludge immobilized in polymer pellets
January 1, 2000By Matias B. Vanotti
Nitrification of ammonia (NH4+) is a critical component for improved systems of animal wastewater treatment. One of the most effective processes uses nitrifying microorganisms encapsulated in polymer...
Hydrogen sulfide production from stored liquid swine manure: a laboratory study
January 1, 2000By Jactone Arogo
The production of hydrogen sulfide from stored liquid swine manure as influenced by the manure settling characteristics and the initial sulfate concentration was studied in the laboratory. The...
Evaluation of two-stage anaerobic sequencing batch reactor systems for animal wastewater treatment
January 1, 2000
Anaerobic treatment of screened swine and dairy manure was studied in the laboratory with two-stage anaerobic sequencing batch reactor (ASBR) systems. The effects of anaerobic treatment on odor...
Dynamics of Pig Slurry Nitrogen in Soil and Plant as Determined with 15N
January 1, 2000
The fate of pig (Sus scrofa) slurry labeled with 15N was investigated when applied on a clay soil (fine, mixed, frigid, Typic Humaquept) and a sandy loam (loamy, mixed, frigid, Typic Dystrochrept)...
Corn response to composting and time of application of solid swine manure
January 1, 2000
Swine production in hoop structures is a relatively new husbandry system in which a mixture of manure and bedding accumulates. This manure/bedding pack can be applied to crop fields directly from a...
Ammonia Volatilization and Selected Soil Characteristics Following Application of Anaerobically Digested Pig Slurry
January 1, 2000
Ammonia volatilization occurs shortly following land application of pig slurry. Several slurry and soil characteristics modulate the intensity of this process, and their net effect on volatilization...
A field study on downwind odor transport from swine facilities
January 1, 2000
From the eight swine facilities studied [locations not given], power functions were found to be an appropriate description of the pattern of downwind odour transport for both swine buildings and...
