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®.

2D version : settling + thickening

4D version : grit removal + grease removal +settling +thickening

key figures

  • 8 to 10times smaller footprint than traditional settling unit
  • Sludge volume 10 times lower than ballasted floc systems
  • Sludge from Densadeg® > 30 g.L-1
