Implementation of Disinfection Standards in Bioga Plants-Impact for Practical Work
Most biogas plants are operated in the mesophilic temperature range and usual input materials were liquid manure and renewable primary products sometimes biological waste.Using these temperatures the inactivation of pathogens included in the input materials is not sufficient leading to an epidemiological risk of the fermentation residues (transmission to soil,groundwater etc.).To minimize this risk biological waste has to be pasteurized(70℃/1h)before it can be put into the fermentation process.One alternative to this procedure is the operation of the biogas plant in a thermophilic temperature range (>50℃).Nevertheless,the efficacy of the inactivation potential of this process variant has to be proved.This is done by the validation of the inactivation capacity tested against the typical process validation bacterium Salmonella Senftenberg.The validation process performed in one biogas plant is reported.
