Case Studies

Innovative vacuum distillation technology from H2O reliably ensures compliance with strict limits for disposal of water into watercourses.

Innovative and space-saving evaporator technologies from H2O GmbH can achieve a high treatment quality for wastewater contaminated with mould release agents and cooling lubricants.

Less maintenance, better quality, more automation - that's what RDO Springs wanted to achieve with their new wastewater treatment. The decision was made in favour of an energy-saving VACUDEST system: "Now we can finally make better use of our resources!

While relocating its production line, a manufacturer of high-end sealing systems for powertrains in China considered a new wastewater concept. For the company, which specializes in precision seals and modules made of elastomer, metal, and plastic materials for the automotive industry, environmentally compatible processes and the efficient use of water as a resource are important aspects.

At Rabas Protec in Saint Nazaire, France, aluminium parts are produced, mainly for the aerospace industry. After mechanical processing, the parts are anodised and painted to protect them from corrosion. To do this, the surfaces of the parts are first prepared in degreasing baths, followed by sodium and acid pickling. Before the surface treatment, an NDT test can be carried out using dye penetrant testing. The final step is painting.

The demands placed on components in the automotive industry are becoming more and more stringent - as a result, the requirements placed on manufacturers and suppliers in terms of cleanliness are also increasing.
