ION EXCHANGE SYSTEMS & METAL RECOVERY

For sustainable production

Special filter technology and water treatment ensure clean process water. In addition to a large selection of solid filters, we offer ion exchanger systems from the IONEX series, which enable the continuous cleaning and reuse of rinse water from rinsing baths and economy rinses. This contributes to an increase in circulating water quality and significant water savings.
