mesophilic digestion - 37°C – Digelis®
The Digelis® is a 1 stage anaerobic digestion process for sludge coming from urban wastewater treatment plant.
An efficient temperature regulation and an efficient sludge mixing are essential to the good operation of the digestors.
Digelis® is adapted for the treatment of primary sludge, biological sludge, high, medium or low load, extended aeration and mixed sludge.
key figures
- Over 40 % of sludge potential energy can be valorized via energy produced from biogas
- Sludge volume divided by 2 compared to line without digestion

- Alexandrie Est (Egypte) – 4,500,000 PE (Digelis®)
- La Feyssine (France) – 300,000 PE(Digelis®)
profit
- Reduction of sludge quantity: 20 to 40% of dry matters
- Long-term sludge stabilization : nuisance reduction & sanitation
- Sludge recovery for green energy through biogas production which can be injected into the natural gas grid or used to produce biofuel.
- Increase of the dryness in dewatering
- Reduced maintenance costs
- Synergy with advanced heat treatments
