Biogas Production from Wastewater Treatment Technologies are prevalence because there are advantages in two ways 1) wastewater treatment and 2) biogas production. Biogas is clean energy that important for national development. The popular for biogas production technologies are 1) Modified Covered Lagoon 2) Completely Stirred Tank Reactor (CSTR) 3) Anaerobic Activated Sludge (AAS) 4) Anaerobic Fixed Film (AFF) 5) Fluidized Bed 6) Anaerobic Hybrid Reactor 7) Upflow Anaerobic Sludge Blanket (UASB) 8) Extended Granular Sludge Bed (EGSB) and 9) Internal Circulation (IC). There are effective technologies due to easy to control, less sludge from system, and can be used for high organic loading rate (OLR). Moreover, these technologies are clean development mechanism (CDM), carbon credit, and less greenhouse gas for sustainable energy development.
