چکیده انگلیسی
To develop this comparative, in this study was necessary to determine experimentally the HRT in which maximum methane production was reached (optimum HRT) using UFAF technology. Bio-hydrogen effluents resulting of the dark fermentation of OFMSW coming from a full-scale mechanical-biological treatment plant was used as feedstock. To determine the optimum HRT, a sequential decreasing of this operational parameter from 7.5 to 1.5 days was established. The results obtained indicate that the maximum specific methane yield, 0.26 and 0.28 LCH4/g CODr respectively, were obtained at 3 days HRT in mesophilic (35 °C) and thermophilic (55 °C) regime of temperature. Finally, the comparative analysis showed that the methane production of the new scheme based on methanogenic-thermophilic UFAF reactor is approximately 4 times higher than methanogenic-thermophilic CSTR (2.00 versus 0.48 LCH4/L/d respectively) and, in addition, higher methane percentage on biogas is reached (75.9% versus 70.6% respectively).
