The residues produced on swine breeding farms, rich in organic matter and pathogens, are frequently responsible for the pollution of the soil, air and water. Among the alternatives found to solve the environmental impact caused by the large amount of residues produced on a pig breeding farms, the upflow anaerobic sludge blanket (UASB) reactor can be used as an alternative for the treatment of wastewaters with low solid content, to reduce the polluting power of the residues to a minimum. There is a concomitant production of biogas as subproducts of the process, which can be used for practical applications on rural properties. It was determined the concentrations of chemical oxygen demand (COD), phosphorus (P), nitrogen (N), zinc (Zn), copper (Cu) and sodium (Na) in swine wastewaters along treatment in UASB reactor. The biogas production was calculated to evaluate the energetic potential of swine wastewaters. The results shown that anaerobic technology with UASB reactor can feasible in the treatment of swine wastewater, reducing the volume and the polluting power of the residues to a minimum.
