Deionized water for galvanic baths

Deionized water is essential for the electroplating baths used to treat the surfaces of watch movement parts. The selective ion exchangers required for this are reprocessed by a regeneration service.

The faces of watches are created in the heart of Europe. High-quality dials and precision mechanical movement components for renowned national and international watch manufacturers. For over 65 years, Cador GmbH has specialized in the manufacture of fascinating dials for wristwatches, pocket watches, on-board clocks, dial gauges and precision milled parts. From in-house toolmaking to precision assembly, all specialist areas are united under one roof in Eimeldingen - in the border triangle of Germany, Switzerland and France.

The wide range of surface treatments such as polishing, various blasting and effects, combined with the electroplating baths, result in an almost inexhaustible variety of options for the production of dials and movement components. The electroplating processes used to refine and protect dials and high-quality watch components contribute significantly to the quality and longevity of the watches.

If you want to master the production of high-quality dials and watch components, you have to look above, below and next to the dial. This also applies to the electroplating processes, which require demineralized water (demineralized water), also known as demineralized or deionized water.

The quality of the water used must meet strict standards of purity and conductivity to ensure a uniform and flawless coating. This is because the quality requirements of watch manufacturers in terms of precision and perfection are subject to the highest criteria.

The experts at EnviroFalk have adapted to the different needs of industrial water purification and water treatment. This also applies to companies in the watch industry and watch component manufacturers. From compact water treatment plants for standard applications to individualized plant construction and a comprehensive range of services, EnviroFalk develops perfectly coordinated solution concepts.

Selective ion exchangers can be used to remove dissolved heavy metals from galvanic rinsing water. And to such an extent that the limit values for discharge into the public sewage system are easily met.

However, the special selective exchange resin inside the cartridge systems is exhausted after a certain loading time and requires professional regeneration. The experts at EnviroFalk have been offering a regeneration service for selective exchangers for more than 35 years. State-of-the-art technology and in-house water circuits ensure a resource-saving operating process in the EnviroFalk regeneration station for ion exchange resins. In addition, the regenerates and rinsing water produced are also treated in the special waste water treatment plant.

Numerous stacking tanks, extensive batch treatment tanks and sludge tanks are available for this purpose. The sludge produced is dewatered using chamber filter presses. The resulting clear water is then passed through selective exchanger lines and discharged into the sewage system in compliance with all limit values in accordance with the WHG.

Mobile selective ion exchangers are particularly interesting when small quantities of wastewater, low loading quantities and widely varying wastewater quantities are produced. EnviroFalk also has a permit that allows it to collect and transport selective ion exchangers loaded with heavy metals. The service does not just include ion exchanger regeneration. EnviroFalk collects the exhausted selective ion exchangers on site and returns them to the customer in a reconditioned state.

Andreas Reisch, Managing Director at Cador: "With EnviroFalk, we have a partner for water treatment at our side who understands the requirements of our electroplating processes precisely. And the fact that we have the option of having the ion exchangers loaded with heavy metals recycled is extremely important for us in terms of sustainability. After all, the responsible use of all natural resources is firmly anchored in our corporate culture." (OM-9/24)
