lamellar and sludge contact clarifier – Densadeg®
Clarifier with optimized flocculation using external sludge recirculation
The Densadeg® treats all types of water. In drinking water production, the Densadeg® is used for clarification (removal of suspended solids, colloids, color, micro-algae, etc.), carbonate removal (softening).
It combines the principle of lamellar settling with an integrated sludge thickener. No need of additional sludge thickening equipment before dewatering. The densification of sludge allows to reduce the volume of extracted sludge and thus limit the water loss.
For suspended solids removal to versions are available, 25 m/h or 35 m/h, depending on the raw water quality (from 5 to 2000 NFU)
key figures
- Sludge > 20 g/l
- 5 to 10 times smaller footprint than traditional settling unit
- Up to 95% of efficiency
- Application to river water or dam water (from 5 to 2000 NFU)

profit
- Compactness due to its modular and lamellar design
- Advanced treatment of Suspended Solids (SS) and organic matter
- Integrated sludge thickening - particularly suitable in case of small footprint or if water loss should be limited
- Fast and easy operation even in case of important variation
