Impact of hydrogen potential on anaerobic digestion of organic waste

The world’s waste deposit has become more important due to the growth of world economy and demography. Biomethanation is method choice for treatment fermentable fractions municipal waste. However, low methane yield operational issues process instability prevent this technology from being widely applied. It shows that biogas made up approximately 50-70% CH 4 ; 30-50% CO 2 traces other gases. Solutions improving production include controlling anaerobic digestion factors. These factors are essentially: methanogenic potential, carbon/nitrogen ratio (C/N), temperature, Hydrogen potential (pH) tightness reactor. Among these factors, one most important, pH, analysed in article order ensure production’s optimization. 02 substrates studied potato peel cow’s stomach waste: As results, varies constantly with variation pH. With a pH lower than 5 decreases. best productions were obtained value between 6.9 7.4. That said, it find way stabilize better sustainability. Eggshell been maintain balance good results have obtained.
