Selective Ionexchanger units with external regeneration SE 30 – 250 for water treatment

For our ion exchanger units we offer ion exchanger 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 exchangers are used for

selective ion exchanger for the removal of heavy metals / pollutants
recirculation of rinsing water (type KR)

The transportation of the ion exchanger 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

complying with limit values
reclaim of metals
easy to handle

Application of selective ion exchanger 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 exchanger cartridges.
After having removed loaded ion exchanger cartridges ion exchanger the security cartridges move up and fresh regenerated cartridges are added at the end of the sequence.

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 exchanger 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.
