Water discharged treatment
Fluid effluents from our facilities are subjected to purification treatments to minimize their environmental impact and ensure compliance with legal requirements. The type of wastewater treatment process is specific to the activity and the characteristics of the site. Treatment may be a physical-chemical (primary) process, completed with a biological (secondary) process, or even include more advanced treatment (tertiary process) or other specific processes for contaminants that are non-degradable using non-conventional processing techniques.
Some 36% of water discharged undergoes advanced treatment processes, 18% undergoes secondary processes and the remaining 46% undergoes primary processes as the quality of the discharged water does not require more complex treatment.
Main contaminants discharged
The main pollutants discharged at our facilities are: hydrocarbons, suspended solids, and organic matter likely to undergo oxidation, measured as Chemical Oxygen Demand (COD).
