thermophilic digestion at 55°C - Digelis® Fast
Digelis® Fast is an optimized process for thermophilic sludge digestion combined with energy recovery equipment to accelerate the sludge digestion cycle.
Digelis® Fast is capable of accepting high loads and providing shorter contact time for the sludge and then smaller reactor size.
Spiral Heat Exchanger : A unique feature to preheat the fresh sludge and to avoid any energy over-consumption.
