physico-chemical lamellar clarifier – Densadeg®
Combines a fast primary physico-chemical settling and sludge densification.
The Densadeg®is a lamellar physicochemical settling tank with sludge recirculation which treats all types of water. It is a proven process which integrates the functions of:
- Coagulation (with hydrolyzing metal salts)
- Flocculation (with polymer)
- Lamellar settling (which increases the speed of clarification and decreases footprint)
- Sludge densification
For WASTEWATER applications, two models exist:
- Densadeg® 2D: primary treatment (45 m/h), wet weather (100 m/h)
- Densadeg® 4D: primary treatment integrating grit and grease removal(45 m/h)
2D version: settling + thickening
4D version: grit removal + grease removal +settling +thickening
key figures
- 5 to 10times smaller footprint than traditional settling unit
- Sludge volume 10 times lower than ballasted floc systems
- Sludge from Densadeg® > 20 g.L-1

profit
- Compactness of the equipment due to its modular and lamellar design
- Very high settling efficiency
- Integrated thickening (>20 g/l) eliminates the need to build an additional thickening structure
- Fast and easy operation even in case of great variation in flow and/or load
- Flexible fitting option: can be tailored to every plant size
