Trouble-free operation is guaranteed by the Decker regeneration service for exhausted demineralisation cartridges.
Examples of useMixed-bed ion
exchanges with regeneration service are ideal for the production of
demineralised water with a requirement of up to 2m³ per week (e.g. for
the new preparation of electrolutes in the electroplating). For the purification after reverse osmosis systemsReverse osmosis systems remove up to 97% of dissolved salts, i.e. with a conductivity of f. ex. 400 µS/cm of the inflowing water a demineralisation up to 12 µS/cm will be achieved. With a mixed-bed exchange installed downstream a demineralised water with a conductivity < 1µS/cm can be generated with long operation time of the mixed bed resins. For the recirculation of pure water, as final rinsing to achieve stain-free drying of the product surfaceBy combining activated carbon, cation exchange and anion exchange and downstream mixed-bed exchanges pure water of high quality can be produced (conductivity < 0,1 µS/cm). Recirculation of final rinses is possible at temperatures up to 70°C. The recirculation of the hot rinse at the end of the rinsing sequence has proven of value especially for manufacturers of sanitary fittings. Recirculation of demineralised water used in electrical discharge machining (EDM)EDM processes require demineralised water which has to be constantly replaced. The exhausted mixed bed resins can be recycled with a service-regeneration. Single-use resins will be disposed as hazardous waste. Regeneration/External regenerationThe exhausted mixed
bed cartridge resp. the resin filled in a transport container will be
delivered to Decker Verfahrenstechnik. A pick-up service is also
possible. In the central regeneration plant cation and anion resins will
be separated and regenerated with hydrochloric acid or sodium hydroxide.
After proper rinsing the resins will be mixed again.
