Tiivistelmä
This research was done as an internal project for developing in-house knowledge for PROCES-Groningen B.V. The project is related to bio-digestion and factors affecting the process. The bio-digestion process is taken into account which includes the digesting of corn and ammonia removal which occur after digestion. The aims of this research are to analyze parameters affecting bio-digestion and provide the framework for a construction of a better bio-digester.
The digestion of corn analysis was done with thermophilic and mesophilic digesters where the gas production, pH, volatile fatty acids content and lignin content was analyzed. The ammonia removal was done with air stripping method where both flocculated and drain digested pre-treated chicken manure was used. The varying amount of air volume was also examined with the air stripping method experiments.
The result of this research will provide a framework for the construction of a better bio-digester. These results will also give a detailed analysis of digestion of corn and better way of removing ammonia which will provide the background for further research. This result will also provide more information about how other future research might be directed.
