Abstract
The technology of two phase anaerobic digestion (TPAD) is different from the other new anaerobic reactors. It focuses on the changes of technologies, not on the reshape of reactors' structure. The phase-separation is theessential characteristic of this treatment system. Two-phase anaerobic digestion process fixes the acid-producing bacteria and methanogens respectively in two separate reactor in tandem and provide the own best conditions. The two-phase anaerobic digestion has several advantages over conventional one-phase processes, such as selection and enrichment of different bacteria in each phase, increased stability of the process, higher organic loading rates (OLR) and shorter hydraulic retention times (HRT). Furthermore, two-phase anaerobic digestion system has given the best performances concerning methane productivity, so this technology is helpful to alleviate current solution of the energy shortage and explore the new ways for clean energy.
