Decker systems realise in an economically and environmentally conscious way    

  1. Product-related water treatment concepts for your rinse water

Treatment processes

Examples of use

Circulation of rinsing water using ion exchange units from < 0.5 m3/h up to 10 m3/h ith external regeneration (KR30-KR250)
or automatic regeneration (KR1465-KR3072)


Rinsing water containing chromates and cyanides

Selective ion exchange units according to the state of art as security filter downstream to waste-water-treatment plants or multi-layer-filters with <0.5 m³/h up to 10 m³/h. Available with external regeneration (SE30-SE250) or automatic regeneration (SE1465 – SE3072)

Removal of heavy metals to a residual content of < 0.5 mg/l copper, nickel, tin, zinc, chrome.
Ground water remediation with chemical bounding of chromate and cyanide.
Selective removal of nickel in anodization units

Cleaning of process baths with selective ion exchange resins and automatic regeneration

Chrome and FE(III) from chromium-plating.
Precious metals (Gold, Silver, Platinum, Palladium) from concentrated baths or rinses.

  1. Individual treatment concepts for your waste-water

Treatment processes

Examples of use

Neutralization and precipitation of heavy metal loaded waste water in batch treatment installations

electroplating industry, PCB-industry, electrical engineering industry, anodizing industry

Oxidation of cyanide waste-water
Reduction of chromate-containing waste-water

cyanide copper-/ gold-plating
electro-plating of plastics

Multi-layer-filter connected downstream to waste-water treatment plants

Restoration of old plants

  1. Demineralisation systems:
  1. Synthetic material construction bespoke for industry and private.
  2. Ion exchange resin (anion exchange resin, cation exchange resin, selective exchange resin (nitrate resin), mixed bed resin) and regeneration of ion exchange resins.
