The results of a methanogenic activity test (see figure 1) on a sludge to be used as an inoculum for a UASB reactor are shown in table 1. Additional data: Temperature = 35°C, Pressure = 0.974 atm Total solids of the mud sample 180 g/L, of which 50% are volatile solids. R = 0.082 L.atm/mol.K Determine: a) the maximum specific methanogenic activity of the sludge in gCOD/gSV.day b) Comment on the value obtained. Is it an expected value? explain Tabla 1 Time (h) 0 0.25 0.5 0.67 0.75 0.83 0.91 0.99 1.07 1.15 1.23 14.98 16.54 17.14 18.09 20.1 21.5 22.67 24.17 24.8 I. | | | VCH4 (mL) 0 4 6 8 9 50 9.5 10 11 12 12.5 13 212 249 263 269 271 280 291 291.5 292 FIGURA 1 Linea de biogás Digestor Agitutor Tubo trampa Digestor: Volume 500 mL Lodo-5 gSV/L en el digestor Frasco de Mariotto Probeta
