Waste water treatment


The name IONEX stands for ION-EXchanger, which is the very heart of this modern waste water treatment system. The Ionex is a modern and compact plant to treat rinsing water coming form the etching or through-hole-plating machines of a pcb laboratory. We offer 4 basic variants, which differ in rinsing water through-put and ion capacity. Type A and B are equipped with a cotton pre-filter, two cation columns and a ph neutralization column. Type KA and KB have three ion exchange columns.

The cation columns color red, when loaded with ferric ions and blue/green, when loaded with copper ions. Loading of anion column can be testet by measuring the conductance of the cleaned water.

Loaded columns can be sent to Bungard for regeneration or we support you to do the regeneration yourself. The drain water quality from this system is in accordance to German directives, which are of the highest standards world wide!

As an option the IONEX can be equipped with a conductance meter (IONEX KA/KB) or a ph-meter (IONEX A/B). This way you have the quality of the treated rinse water always under control.


Closed loop rinsing water:

IONEX KA and KB fi lter next to the metalic cations also the anionic halogens from the rinsing water, so you receive demineralized water. The demineralized water is collected and pumped back to the etching or throughhole-plating machine.

Of course the machines of the IONEX family can be adapted according to your needs. The IONEX XXL e.g. cleans 1500 l of rinsing water. The IONEX AU fi lters gold ions out of rinsing water from a nickel-gold-processing machine. These gold ions can be regenerated and returned to the gold bath.

Labion 2

Ion exchanger for fresh water cleaning. After treating your fresh water with LABION 2 you will receive demineralized water, which is necessary e.g. for through-hole-plating machines. Full system incl. µSiemens conductivity measurement and readout via diodes:

0,1 µSiemens - 1. green diode

5 µSiemens - 2. green diode

20 µSiemens - 1. red diode

50 µSiemens - 2. red diode
