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

Description
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.
