Wet Digester

The digestion process can be separated in wet and dry fermentation. Particularly in Germany wet fermentation is the more common process for biogas production. Generally, fermentation with wet digester is cheaper, faster and easier to automate compared to dry fermentation. The reason for this widespread use is also because most biogas plants are built on agricultural farms. Here, the agricultural farms are operated primarily with renewable raw materials and manure. These are optimal conditions for the wet fermentation process.
