Bringing the discharge standards of the LU cake factory up to standard

In 2016, MONDELEZ (LU cakes manufacturing) in the Hauts-de-France had a recurrent excess on its discharge standards. With its partner GEMAD, ExoCell proposed the aeration of the buffer tank and a separation of the sludge by dissolved air flotation.

Installed equipment:

  • Surface aerator on buffer tank,
  • Flotation tank: FloliBull XS
  • white-water generator: NanoBull S
  • reagent dosing: Dozel and PolyBull,
  • ElectriBell control unit to control the equipment.


Installation performance

Parameters Input Output
Flow m3/h 5
COD mg/L 8000 300
SS mg/L 3000 200

Highlights of the installation:

  • SA compact solution to meet space constraints,
  • Corrosion-resistant equipment,
  • No submerged elements for easy maintenance,
  • optimised reagent consumption.
