We are able to provide quality water and treat all known pollutants to ensure profitability and compliance for customers.

Water treatment for car industry - White car, doors opened, staff working.

We produce quality water for surface treatment.
We treat wastewater appropriately and specifically for the needs of the automotive industry.
We find value in used sludge through special treatments.

For customers concerned with preserving water on a global and local scale, we can provide technologies to further optimize use. We have a wide range of tools, specially adapted to the needs of car manufacturers, that can help minimize the amount of waste. Our continuous innovation generates productivity and profitability gains while reducing any negative environmental impacts.

Adaptable solutions for all automotive players

Process water

Our technologies produce process water and demineralized water, and treat polluting effluents using membrane processes for water treatment. These facilities can be permanent or temporary, providing relief in urgent situations. 

Zero Liquid Discharge

Aware of our customers' concerns, we manage and develop zero liquid discharge (ZLD) solutions. By implementing a global approach to the production circuit, we can optimally help you control water consumption and improve the water cycle during the industrial process. This provides a secured production while limiting water needs. Cost-efficient, zero liquid discharge is a defining technology when looking to meet strict environmental standards. 

Veolia Water Technologies ensures PWIS-free water

Silicones, substances containing fluorine, certain oils and fats can contain PWIS (Paint-Wetting Impairment Substances) causing craters, punctual, funnel-shaped depressions in the paint layer. Elements that are used in the automotive industry and especially in paint shops must be PWIS-free. 

Automotive wastewater treatment

Mechanical processing of metals and high-pressure die casting and foundry

  • Foundry effluent
  • Used cooling lubricant 
  • Release agent solution

Parts cleaning & washing water

  • Parts cleaning effluent
  • Washing place effluent
  • Container cleaning effluent

Metal surface treatment

  • Surface grinding
  • Hardening effluent
  • Crack testing effluent 
  • Degreasing bath

Coating technology

  • Activated bath

Recognized partner of major international car manufacturers

At Veolia Water Technologies we are recognized for our global expertise and are a proud partner to the largest automotive groups, including world-renowned manufacturers such as PSA, Volvo, and Renault.

As part of Veolia group, Veolia Water Technologies manages six main sites and 19 other sites for the PSA automobile group. Our experts are responsible for water treatment at all of these sites, helping reduce the manufacturer’s environmental footprint. Veolia group was awarded the “Industrial Equipment and Services Performance” trophy in 2017.

Veolia group worked alongside manufacturer Renault to create sustainable automotive facilities in Morocco. These facilities are among the most modern across the globe, particularly when looking at how they use water. With zero liquid discharge technologies in place, the site does not produce any industrial liquid discharge. This efficient reuse of water reduces the overall water needs of the facility by 70%, a major ecological breakthrough.

FAQ about water solutions for the automotive industry

When is water used during car manufacturing?

In automobile production, water is mainly used to rinse and clean treated surfaces. For example, a lot of water is needed to paint car bodies, but also to manufacture individual parts such as connectors, engine parts, gear parts and the like. As a rule, the automotive suppliers need more water in their production than the automotive manufacturers themselves.

How much water is used for car manufacturing?

If one looks at the entire supply chain of automobile manufacturing, from the extraction of raw materials, the production of the individual parts to the assembly of the vehicle at the automobile manufacturer, the water consumption per vehicle is estimated at around 400,000 liters. Of course, this is an average value which varies greatly depending on the vehicle size and equipment. 

Which processes are used for automotive wastewater treatment?

The most common processes for treating wastewater in the automotive industry are vacuum evaporation, chemical-physical wastewater treatment, membrane processes and mechanical treatment processes. The process is selected depending on how large the amount of wastewater is and which criteria the treated wastewater must meet or whether zero liquid discharge is required.

How can car manufacturers save water in their production processes?

The first approach to save water in production is to optimize the flushing processes of the individual processing steps so that as little wastewater as necessary is generated. Of course, the quality requirements for the product still have to be met. In the second approach, for example, a vacuum evaporator can be used to produce process water from wastewater and feed it back into the production process.

Which water treatment technologies are required for e-mobility battery production?

Large amounts of wastewater are generated when the raw materials are extracted for the batteries. Here, too, the process to be selected is heavily dependent on the volume of wastewater and the degree of pollution. A common method for treating wastewater from the production of batteries is, for example, vacuum evaporation. This also enables wastewater to be recycled, i.e. zero liquid discharge.
