Sub-optimal conditions fermentation process

The operations of the WWTP can be more efficient.

In traditional fully mixed fermentation of sewage sludge, all sub processes take place simultaneously, resulting in sub-optimal conditions.

Ephyra is a frementation technology where sub-processes of the fermentation process run seperately. This leads to a decrease of influence between the sub-processes ensuring a more efficient fermentation process. This results in higher sludge degradation and biogas production.

• Ephyra is an optimization of the current fermentation process and therefore easy to implement.
• The residence time of the sludge in the fermentation reactor is considerably shorter.
