Recycling of
nickel out of rinse water and selective ion exchange SE1465Me –
SE3072Me
- high enrichment of Nickel in the eluate
- fully automatic regeneration
- recycling of Nickel by external treatment or electrolysis
- compliance with the prescribed waste water limit values
- due to the removal of Nickel
the remaining aluminium sludge of anodization units is no hazardous
waste.

Ion exchange stationary recycling of Nickel / Nickel reclamation
Description
The unit consists of two ion
exchange cartridges which are operated in-line. After having completed
the regeneration the fresh regenerated cartridge is operated downstream
to the other cartridge (Lead-Lag-Operation). The process adheres at any
time to the prescribed limit values for nickel.
For regeneration sulphuric acid is used. In this procedure the
regenerating acid is used several times to create a recyclable
concentration.
A fraction of the Nickel-concentrate is removed at each regeneration and
replaced by fresh acid. No Nickel-loaded rinsing water will be disposed
as it remains in the system as feeding.
Acid and sodium hydroxide can be pumped from original containers if no
storage tank is available.
