ORGANIC MUD FROM BIOGAS PRODUCTION: DIGESTATE
What is digestate?
From anaerobic digestion aimed at the production of biogas you get an organic matrix waste, exhausted in terms of biogas production at the pumpable physical condition here defined digestate .
The digestate is normally used in agriculture with particular attention to nitrogen value, in fact the nitrogen entering the digester is equal to the outgoing one.
With the aim to control the nitrogen and to facilitate the storage and spreading, by dehydrating the digestate you obtain two phases: a shoveling phase and a liquid phase, each one holding a percentage of nitrogen.
The liquid phase is more easily treated until total recovery of the plant, and by shoveling it can be spread on agricultural soils.
