Installed equipment:

  • Flotation tank: FloliBull S,
  • white-water generator: NanoBull M.

Installation performance

Parameters Input Output
Flow m3/h 20
SS treated water mg/L 800 10
SS floated sludge g/L 25

Highlights of the installation:

  • A compact solution to meet space constraints,
  • Corrosion-resistant equipment,
  • No submerged elements for easy maintenance,
  • Optimised energy consumption, 4 times more energy efficient than the previous installation.
