| Abstract |
The present work consisted of the energetic valorization of sludge from wastewater treatment plants and dis-charges from the wine sector by means of anaerobic co-digestion. The valorization was approached through the application of two different processes: a) single-stage mesophilic anaerobic digestion process (35 degrees C) and, b) Temperature -Phased Anaerobic Digestion (TPAD) with separation of microorganisms: thermophilic acidogenic (55 degrees C) and mesophilic methanogenic (35 degrees C) phases.Mesophilic methanogenic biodegradability tests (BMP) were developed to determine the biogas (methane) production yield in single-stage process and sequential thermophilic hydrogen (BHP) and BMP were developed to study the biogas (hydrogen and methane) production yield in anaerobic co-digestion processes in TPAD process.The results obtained showed that the single-stage mesophilic anaerobic co-digestion process was more effective for methane generation with yields of 55.39 mL CH4/g VSadded for the sludge and vinasse mixture, compared to 45.79 mL CH4/g VSadded for the TPAD process. |
