Treatment of wastewater generated by the automotive manufacturing process
Effluents come from various process stages, with the bulk of the pollutant charge steaming from:
- Bath purges
- Rinses after phosphatation
- Rinses after passivation
- Eluates from the recycling installations
Surface treatment discharges numerous types of pollutants depending on the type of treatment used. Those most commonly found in effluents are oils, chromium and phosphates to which are added the solvents and binding agents discharged by the cataphoresis baths (heavy COD charge).
A physical-chemical treatment (oil removal, metal abatement, etc.) is usually used to treat the effluents, followed by a biological treatment for COD abatement.
