Figure 4.8 Variation of methane production rate and methane production yield achieved 60
from CH 4-UASB reactor at different HRTs under thermophilic temperatures;
[1, 4] BA medium + sucrose 2 g/L, [2] (BA medium + sucrose 2 g/L) + effluent H 2
at 1:1 (%v/v), [3, 5, 7] BA medium + Effluent H 2 and [6] Effluent H 2 + NaHCO 3
2 g/L
Figure 4.9 Variation of pH in CH 4-UASB reactor which was operated at different 61
HRTs under thermophilic temperatures; [1, 4] BA medium + sucrose 2 g/L,
[2] (BA medium + sucrose 2 g/L) + effluent H 2 at 1:1 (%v/v),
[3, 5, 7] BA medium + Effluent H 2 and [6] Effluent H 2 + NaHCO 3 2 g/L
