Our achievements

The treatment process used is activated sludge in free culture with alternating phases
(anoxia and aerobia). The station consists of the following stations:

  • A wastewater pumping chamber (with pebble trap, screening basket
    and above ground self-priming pumps);
  • Screening: channel screen press (5 mm mesh) and storage container for the
    waste ;
  • A biological treatment: anoxic-aerobic basin aerated by fine bubble diffusers of
    Messner plate type and degasser;
  • Two blowers placed in the dry cellar supply the aeration frames;
  • A 7.80 m diameter clarifier with a central drive and radial scraper bridge;
  • Two pumps in dry cellar for recirculation from the bottom of the clarifier to the
    biological basin ;
  • A sludge silo with a storage capacity of 32 m³ corresponding to
    approximately 15 days of storage for a thickening to 30 g/l ;
  • A screw pump placed vertically on one of the sails of the dry cellar allows the purging of the sludge from the recirculation circuit to the silo thickener;
  • A venturi channel to measure the treated flow;
  • A low voltage panel installed in the operating room.
