physico-chemical settling tank using external sludge recirculation – Densadeg®

physico-chemical settling tank using external sludge recirculation – Densadeg
Combines a fast primary physico-chemical settling and a sludge pretreatment by thickening.

The Densadeg® is a compact system which includes stages of coagulation/flocculation, water clarification (lamellar zone) and settling/thickening of sludge. For the wastewater treatment plants the grit removal and degreasing stages can also be performed within the Densadeg®.
