Upgrade Waste Water Treatment 3

closed loop water circuit → no need for fresh water or connection to canalisation
Removal of solids and all heavy metals → waste water regulations can be met
Decrease of chemical oxygen demand
Special solutions on request

The machine is connected to an etching, developing or plating-through hole machine
Rinsing waters from the machines are collected in the AquaPur
Tank capacity: max. 250 l
Cleaning capacity: about 400 eurocards or 4000 pre-rinsed eurocards
Water throughput ion exchanger: 250 l/h
5 cleaning steps:
- Filter screen
- Active carbon filter 100 μm
- Active carbon filter 10 μm
- First ion exchange column with mixed bed resin for cat- and anions conductivity meter
- Second ion exchange column with mixed bed resin for cat- and anions
  Continuous cleaning process in by-pass-loop of the main pump.

Main quantity is pumped back to the rinse zone of the etching or plating through-hole-machine
