Surface Treatment

The water needs of surface treatment plants are significant and result in a large amount of effluents.

Supplying static and current rinses, assembling new baths, washing filters and tanks — there are so many operations that generate water rich in pollutants carried away from the treatment baths.

Although the use of commercial products with less harmful environmental impacts is becoming more widespread, water from rinsings still contains pollutants, which are often very toxic and must be eliminated.

We treat this water before they’re discharged into the environment or at the municipal wastewater treatment plant:
