Swine operations: comparison of biological filter media for odor control and wastewater treatment
January 1, 2000
Researchers at Mississippi State University have been studying the effectiveness of the attached growth process for swine wastewater treatment and odor abatement for the past three years. Organic...
Survival of zoonotic pathogens in soils and runoff water after application of swine manure
January 1, 2000By Sagar M. Goyal
Because of increased scrutiny of manure handling practices, it is important to determine the most appropriate practices for manure application on soil. This study was undertaken to determine the...
Two airspace building design to reduce odour and gas emissions from pig farms
January 1, 2000By S.P. Lemay
By keeping manure storage into the building and creating two independent airspaces within a room (main airspace and an enclosed dunging area [EDA]), it is suggested that the building air quality...
Odor and gas emissions from anaerobic treatment of swine waste
January 1, 2000
Odour and gas emissions from commercial swine lagoons were measured using a buoyant convective flux chamber (BCFC). Normal- and lightly-loaded lagoons were selected to determine the effect of loading...
Residual effects of composted and fresh solid swine (Sus scrofa L.) manure on soybean [Glycine max (L.) Merr.] growth and yield
January 1, 2000By G.M. McAndrews|M. Liebman
Applying livestock manure to soil can enhance soil fertility and crop growth; however, little information is available on the residual effects of manure on crop growth. The objective of this study...
Design and analysis of a pilot scale biofiltration system for odorous air
January 1, 2000By John J. Classen
Three pilot-scale biofilters and necessary peripheral equipment were built to clean odorous air from the pit of a swine gestation building at North Carolina State University. A computer measured...
Laboratory measurement of hydrogen sulfide and sulfur dioxide releases from swine manure of different solid contents
January 1, 2000
Releases rates of Hydrogen sulfide (H2S) and sulfur dioxide (SO2) from finishing swine manure of two different solid contents and two initial manure accumulation days were measured under laboratory...
Swine effluent application timing and rate affect nitrogen use efficiency in common bermudagrass
January 1, 2000By Read J. J.
Bermudagrass (Cynodon dactylon (L.) Pets.] hay production is integral to manure management on southeastern swine farms. But swine effluent timing must be synchronized with crop nitrogen (N) demands...
Phototrophic anaerobic lagoons as affected by copper and zinc in swine diets
January 1, 2000By J. E. Gilley
Odor emissions from anaerobic lagoons containing large populations of phototrophic bacteria are usually minimal. This study was conducted to determine whether copper (123 ppm) and zinc (2,310 ppm) in...
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...
