Abstract |
By refining the existing ADM1 to incorporate a pH inhibition equation on methanogenʼs decay, the critical pH for acid failure was determined during anaerobic fermentation of food waste. The optimal operating conditions for efficient VFA recovery were established by simulating experimental data from other researchers. A range of pH parameters affecting methanogens was identified. For conservative operations, employing low pH inhibition parameters (pHUL=6.41, pHLL=5.47 and n=0.23) allows for stable methane fermentation against acid failure. On the other hand, optimistic curves (pHUL=5.55, pHLL=5.11 and n=0.24) can be utilized to decrease the specific decay rate of methanogens by 0.4 d−1, thereby promoting adequate acidification and maximizing VFA yield. Experimental results indicate that the optimal pH range for activity of acid-producing bacteria is between pH 5.5-6.2, which also benefits VFA recovery by significantly reducing VFA consumption due to acid inhibition. |
