| titleOfInvention | Biogas process with nutrient recovery |
| abstract | The present invention is a method of two-phase anaerobic digestion in which monitoring and adjustment of nitrogen status (carbon to nitrogen molar ratio, ie C/N molar ratio or total nitrogen or total ammonia nitrogen content) enables optimum conditions to be maintained during the process. The method improves the use of various feedstock materials or facilitates single digestion of a feedstock. In particular, the introduction of nitrogen-rich feedstock materials in the process is modified. The communities of hydrolyzing and acid-producing microorganisms in the first-stage digester undergo ammonification, that is, the release of organic nitrogen into ammonia. Nitrogen and phosphorus are removed and recovered from the digestate, which then undergo biogasification in the second stage of the process. Wastewater from biogasification can be recovered within the process. |
