Abstract
AbstractThe parameters characterizing and affecting anaerobic sludge digestion process in three Lithuanian cities are investigated. Results showed that digestion process was effective in all three objects: specific biogas production varied between 0.77 and 0.86 m3/kg volatile solids destroyed, methane content in the biogas varied between 64 and 67% and they complied with the values presented in the scientific references. The increase of VS loading (up to 2.6 kg VS/m3/day) led to the higher level of VS destruction which was up to 59%. The sludge retention time (hydraulic retention time) values must be in ranges of 20–25 days for the digestion process in order to get the design VS destruction, as well the biogas production. In a case of lack of raw materials, the application of wastes from food industry can help to reach the design parameters. The application of wastes from milk industry showed positive results in the digestion process.
