For our ion exchange
system we offer ion exchange cartridges with fillings from 10 litres
resin up to 250 litres resin.
With our service regeneration we offer an economic-priced, fully
developed technology. A 2-shift operated recirculation system with a
flow rate of 1.5 m³/h saves expenses for fresh water of approx. 30,000 €
per year.
The ion exchange
systems
are used for
The transportation of
the ion exchange cartridges to our central
regeneration plant in
D-92348 Berg can be carried out by our pick-up / delivery service or by
a forwarding agency. For this we offer special transportation boxes.

Selective unit
Application of selective ion exchange units
-
selective removal of
heavy metals such as copper, nickel, zinc, lead, cobalt, cadmium, mercury,
chrome, etc downstream to waste-water treatment units, ultra- and
micro-filtration units, heavy-metal loaded rinses.
-
Selective removal of
heavy metals or Cyanides in groundwater remediation
-
Reclaim of precious
metals such as Gold, Palladium, Platinum
Description
The rinsing or waste
water is fed into a storage tank. A level controlled pump delivers the
rinsing or waste water over a filter (e.g. multi-layer filter), a
non-return valve and a flow meter through the ion exchange cartridges.
After having removed loaded ion exchange cartridges ion exchange the
security cartridges move up and fresh regenerated cartridges are added
at the end of the sequence.

drawing
Example of use: Subsequent cleaning to remove
the rest of solid and dissolved metals
Example: Waste water: 10 m³/day
Concentration of dissolved metals: 4 mg/l Ni, 3 mg/l Cu, 1 mg/l Cd
With a selective ion exchange unit with selective resin waste water
values of each 0.1 mg/l can be reached. A cartridge with 30 litres of
selective resin is loaded after approx. 125 m³ waste water = 2.5 weeks
until regeneration.
