Large quantities of rinse water are used in production of cars and other vehicles for degreasing and surface treatment of the body. In these cases, it is of great importance that the water is compounded correctly in each of the processes. Apart from this, it is often desired to recycle the water. The purpose is to minimize water consumption and to prevent heavy metals from surface treatment processes to get to the wastewater. This can be done through the process of selective ion exchange.

Boiler water, cooling water, and water for humidification are yet another example of applicabilities within the automotive industry.

The technology for treating industrial wastewater produced in automotive industry makes it possible to separate out the aqueous paint, adhesives, and cutting emulsions released during the production process. The principle of industrial wastewater treatment consists in chemical stabilization, precipitation, and sedimentation, with subsequent filtration and dewatering in a filter press.

Our experts have developed specific water treatment solutions for automobile manufacturers, their suppliers and industries in the metallurgical sector. We provide innovative technological solutions to answer automotive industry needs:
