A 180 000 tons/year unit for the treatment of digestate has been started by France Evaporation for the Op de Beeck company in Belgium during the last quarter of 2016.
This installation combines :
- Hygienisation of digestates
- Falling film evaporator
- Finishing via a forced circulation evaporator
- Stripping of condensates
From a thermal point of view, the Mechanical Vacuum Recompression (VMR) unit combined with the recovery of hot water from the cogeneration engines makes it possible to control the energy costs of the unit, as well as possible.
