Biogas Pretreatment Process
Pretreatment methods and its main goal is to give an overview of the techniques that prove effective in enhancing the biogas production.
Utilization of organic wastes for biogas production using mono-and
co-digestion methods has been widely reported. Despite the multi-stage
reactions associated with the production, hydrolysis as the first step
is crucial and aids in increasing the overall yield. This is based on
the fact that, optimization of hydrolysis step results in decomposition
of complex organic matter into high amounts of monomeric and oligomeric
units that can easily be utilized under anaerobic condition for
generation of biogas.
The target of any pretreatment methods is to
make the available nutrients accessible to most microbial species
which speed up biomass utilization during anaerobic digestion process.
