The main problem during the fermentation process is competition between
microorganisms and provision of favorable conditions for archaea. The
elements like magnesium, sodium and calcium play an important role
during the anaerobic digestion, due to its capability to maintain normal
life activities. Besides magnesium can work like effective catalyst
during the fermentation process. Therefore, this work reports the
influence of the mentioned elements on methane production. Moreover,
mathematical model for biogas production for anaerobic digester was
presented, which based on a continuous technology. This high-activity
and cost-effective mathematical model could improve biogas production
efficiency as a tool support for understanding fermentation process.
