thermophilic digestion at 55°C - Digelis™ Fast

thermophilic Digestion at 55°C combined with energy recovery equipment to accelerate the sludge digestion cycle – Digelis™ Fast
The Digelis™ Fast is an optimized process for thermophilic sludge digestion combined with energy recovery equipment to accelerate the sludge digestion cycle.

Capable of accepting high loads and providing shorter contact time for the sludge and smaller reactor size.
