Using full-scale duckweed ponds as the finish stage for swine waste treatment with a focus on organic matter degradation
The rapid increase in the number of swine has caused pronounced environmental impacts worldwide, especially on water resources. As an aggregate, smallholdings have an important role in South American pork production, contributing to the net diffusion of pollution. Thus, duckweed ponds have been successfully used for swine waste polishing, mainly for nutrient removal. Few studies have been ...

Swine Waste Treatment - Case Study
According to the National Pork Producers Council (NPPC), the United States has more than 60,000 pork producers that annually market more than 115 million hogs, leading to an average total gross income of more than US$20 Billion1. Supporting this industry requires an estimated water demand of 525,000,000,000 gallons/yr (1,990,000,000 m3/yr) according to a 2011 report by the Pork Checkoff ...

Optimization of the thermophilic anaerobic co-digestion of pig manure, agriculture waste and inorganic additive through specific methanogenic activity
The anaerobic co-digestion of three wastes (manure, rice straw and clay residue, an inorganic additive) at different concentration levels and their interactive effects on methanogenic activity were investigated in this work at thermophilic conditions in order to enhance hydrolytic activity and methane production. A central composite design and the response surface methodology were applied for ...

Genotoxicity of swine effluents
This study aimed at the investigation of genotoxic effects of swine effluents from different stages of a treatment system for swine wastes through bioassay of stamen hairs and micronuclei in Tradescantia (clone BNL 4430). No significant differences (p≥0.05) regarding the genic mutations were found in the bioassay of stamen hairs, independently of the effluent analysed. For the genotoxicity test ...

Removal of humic acid from composted hog waste by the white-rot fungus,
Phanerochaete chrysosporium The potential hazards of humic acid (HA) associated with hog waste effluent, coupled with increasing awareness of environmental problems, have prompted many countries to control disposal of effluents into water bodies and to maximize removal of HA. Here we employed the white-rot fungus, Phanerochaete chrysosporium, to degrade the HA in composted hog waste effluent, evaluated by the response ...

A Bayesian network model for assessing natural estrogen fate and transport in a swine waste lagoon
Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine ...

Treatment of synthetic wastewater and hog waste with reduced sludge generation by the multi-environment BioCAST technology
Simultaneous removal of carbon, nitrogen and phosphorus was examined along with reduced generation of biological sludge during the treatment of synthetic wastewater and hog waste by the BioCAST technology. This new multi-environment wastewater treatment technology contains both suspended and immobilized microorganisms, and benefits from the presence of aerobic, microaerophilic, anoxic and ...

4 Common Livestock Stressors (and Solutions!)
Stress occurs when animals are in situations that release their emergency signals for survival, which can be either physiological, behavioral, or physical elements – these situations are called stressors. Although stressed animals may be able to tolerate these for a short period, long-term or multiple stressors can be detrimental. Studies have shown that the effects of long-term ...

Season matters when sampling streams for swine CAFO waste pollution impacts
Concentrated (or confined) animal feed operations (CAFOs) are the principal means of livestock production in the United States, and such facilities pollute nearby waterways because of their waste management practices; CAFO waste is pumped from the confinement structure into a cesspit and sprayed on a field. Stocking Head Creek is located in eastern North Carolina, a state with >9,000,000 ...

Intake and digestibility of ‘Coastal’ bermudagrass hay from treated swine waste using subsurface drip irrigation
Waste handling systems for confined swine production in the upper South (approximately 32–37° N and 79–93° W) depend mainly on anaerobic lagoons and application of the waste effluent to cropland. The main objective of this study was to evaluate the quality of ‘Coastal’ bermudagrass [Cynodon dactylon (L.) Pers.] hay receiving effluent generated from a raw swine waste treatment system designed to ...

Revitalizing a hog waste lagoon
A North Carolina hog grower with a brood barn of 200 full grown sows contacted Reliant Water Technologies to see if we could assist him with one of his waste lagoons. All of his lagoons were identical, measuring only .05 acres in size, and designed to be 8 feet deep. When we arrived at the farm all of the lagoons looked like the one in Figure 1. Figure 1 – Small hog lagoon in North ...
