Treatment of groundwater on the EOLE construction site

In 2018, ExoCell designed the treatment of groundwater required for the EOLE works at Saint-Lazare, Porte Maillot and La Défense. For each site, ExoCell delivered a lamellar settler to thicken the sludge produced and, at Porte Maillot, a dosage of oxidant to eliminate hydrogen sulphide H2S.

Equipment installed:

• Settling tank: ClariDull M
• reagent dosing: PolyBull
• ElectriBell control unit to control the equipment.
