Wastewater treatment: Innovative solutions for surface technology

Effective and efficient, reusing process water (a mixture of water and compound) and feeding it back into circulation during mass finishing can help you both save costs and protect the environment.

Effective wastewater treatment solutions from Walther Trowal

In surface technology, efficient wastewater treatment is crucial in order to fulfil environmental standards and reduce costs. Walther Trowal offers customised wastewater treatment solutions based on decades of experience and innovative technology.

Why is wastewater treatment important?

The process water in mass finishing accumulates with abrasion from workpieces and abrasive media as well as oil and grease. In order to fulfil environmental requirements and reduce costs, this water must be purified. Walther Trowal's wastewater treatment technology offers an effective solution here.

Recirculation or continuous flow system: Which wastewater treatment is better?

The choice between recirculation and continuous flow systems depends on the specific requirements. In around 80 to 90 per cent of applications, the recirculation system is optimal. Here, the process water is permanently returned to the working tank and solids are removed in centrifuges. This saves water, compound and disposal costs.

Reliable disposal of process water

Walther Trowal relies on flocculation and filtration for wastewater treatment. Trowalpur flocculants efficiently remove oil, grease and solids from the water so that the purified water complies with legal regulations and can be safely discharged into the sewerage system. In some applications, the process water cannot be reused, e.g. if you pickle with acid or use different compounds. In these cases, the water must be purified in a flocculation plant and then disposed of.

Centrifuges

Our centrifuges can be used for a wide range of applications, including in paint booths, phosphating baths and for cooling lubricants. The centrifuge technology from Walther Trowal enables gentle cleaning of the process water. Solids are effectively separated while the compound used is largely retained.
