Decker ion exchange recirculation units with automatic regeneration are applicable in surface technologies and electroplating industries.
The regeneration process is connected with the internal waste-water treatment.

Example of use: Recycling of nickel out of rinsing water and selective ion exchanges

  • 2.5 – 10 m³/h recirculation water

  • semi- resp. fully automatic regeneration

  • Reduction of needed chemicals due to lift-bed method

  • Compact construction on a frame made of stainless-steel

  • Applicable up to 70°C

The unit consists of a cartridge with strongly acid cation resin and a cartridge with weakly base anion resin. For special requirements to pure water quality, or if the rinsing water contains cyanides, another cartridge with strongly base anion resin can be added.
If the conductivity exceeds a certain value (e.g. > 30 µS/cm) an alarm will be released and the automatic regeneration will be started by manual activation.

Acid and sodium hydroxide can be pumped from original containers if no storage tank is available.
The single steps of regeneration and washing can easily be adjusted to the local conditions.
