Effect of free ammonia nitrogen on the methanogenic activity of swine wastewater
(Pontificia Universidad Católica de Valparaíso, 2011)
Partial characterization of the polluting load of swine wastewater treated with an integrated biodigestion system
(Elsevier B.V., 2003-11-01)
The stabilization of swine wastewaters from swine confined housing by the combination of a upflow anaerobic sludge blanket (UASB) reactor and waste stabilization ponds is a viable alternative to minimize the environmental ...
SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
(Soc Brasil Engenharia Agricola, 2017-09-01)
The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are ...
The effect of different inoculums on anaerobic digestion of swine wastewater
(Elsevier, 2016-03)
Methane production from swine wastewater was evaluated by using three inoculums: rumen (I1), stabilized swine wastewater (I2) and sewage sludge (I3). Experimental design was based on four treatments by duplicate: T0: swine ...
Chemical attributes of soil fertirrigated with biodigester effluent of swine origin
(2015-01-01)
Swine production is a significant and growing part of Brazilian agriculture. Our objective was to determine nutrient availability in the soil after swine waste applications to pastureland and eucalyptus forestland and then ...
CORN FERTILIZATION USING SWINE WASTEWATER AND SOIL-WATER ENVIRONMENTAL QUALITY
(Soc Brasil Engenharia Agricola, 2017-07-01)
Soil application of swine wastewater for nutrient cycling may represent a correct destination of these residues and reduction in production costs. However, when applied to soil, such residue may cause environmental impacts. ...
Monitoramento sanitário de um sistema integrado de tratamento de águas residuárias da suinocultura
(2003-12-01)
Objective. To assess the potential for contamination of wastewaters from pig farming. Methods. Wastewaters from pig farming were stored in a tank. After 0, 30, 60, 90, and 120 days of hydraulic retention, they were added ...
SOIL CHANGES AND YIELD OF MAIZE FERTILIZED WITH SWINE WASTEWATER
(Univ Fed Rural Semi-arido-ufersa, 2019-01-01)
Swine wastewater can be used as a biofertilizer and promote significant improvements in soil physical-chemical attributes and yield. The objective of this study was to evaluate the effects of swine wastewater application ...
