Designing biogas units for cleaner energy production from different wastewater effluents

摘要

Organic wastewater flows from different industrial sectors and categories represent substantial resources of biomass. An appropriate recovery of this biomass can ensure a renewable energy development and a sustainable process for waste management. In this work, different aspects related to biogas production and energy valorization were explored and presented. The governing fluxes involved in biogas plants were estimated based on their mass and energy balances and using substrate characteristics under different operating conditions. The produced net energy was directly related to process constraints including temperature, hydraulic parameters, and feedstock characteristics. The overall process performances were presented compared and discussed in order to assist design, dimensioning and control of several biogas plants.
