Swine effluent treatment using anaerobic digestion at different loading rates REA
Amaral,André C. do; Kunz,Airton; Steinmetz,Ricardo L. R.; Cantelli,Fábio; Scussiato,Lucas A.; Justi,Karin C..
The industrial swine production is characterized by generation of significant effluent amounts that require treatment. The most adopted practices by Brazilian swine farmers have been wastewater storage in lagoons and its subsequent use as a biofertilizer. Nutrient accumulation in soil and water creates the need for an effective management of these residues. The anaerobic digestion process is an important alternative and low-cost treatment for organic matter reduction. However, its efficiency is limited by the digester capacity of solid degradation, especially at low hydraulic retention times. Thus, the present study aimed to verify the behavior of an upflow anaerobic digester by increasing the organic loading rate. This was accomplished in three stages...
