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.
