Decker selective ion exchange units are stationary systems for the removal of ionogenic heavy metals

  • compliance with the prescribed limit values for ionogenic heavy metals such as copper, nickel, zinc, lead, cadmium etc.
  • easy to use
  • automatic regeneration after manual release
  • no blockings of the resins due to the automatic backwashing program
  • easy to maintain and robust due to chemical resistant steel tanks with nozzle floor and maintenance flanges

Capacity:
25 – 30 g metal / litre resin (mono-Na-form) or
15 – 20 g metal / litre resin (Ca-form)

Operating pH-range: 3-9, ideal range: 6-7
Metal loadings in waste water can be reduced to < 0.1 ppm (Me2+)

Description selective ion exchange (see also: Example of use: recycling of Nickel / Copper)

Usually both tanks are connected in series. This means the water to be treated passes through two filter cartridges.
If a breakthrough of heavy metals is detected after the first cartridge, regeneration for this one cartridge will be initiated.
During regeneration the waste water to be treated passes through the 2nd, less loaded cartridge.

Regeneration proceeds in three automatic steps

  1. backwashing of the filter cartridge
  2. regeneration with acid
  3. conditioning into the mono-Na-form with sodium hydroxide solution

After having completed the regeneration the fresh regenerated cartridge will now operate downstream to the other working cartridge. Thus the waste water will pass again through two cartridges which are connected in series.
