AOP Advanced Oxidation > Waste Waters with Chelates
Destruction of complex waste water
Elimination of organic chelates

We destroy organic chelates for an easy elimination of metals

We eliminate organic chelates in waste waters. After that treatemnt dissolved metals can be precipitated in the exsisting waste water treatment process. By this pre-treatment new processes can be introduced by the client without bigger investments in the waste water facillity. Typiscal applications are:

  • Electroless Copper (bath and waste water) - EDTA, Tratrate, ...
  • Electroless Nickel (bath and waste water) - Citrate, Tartrate, Lactate, ...
  • TSAA - waste water and bath - Tartrate
  • Zinc-Nickel-waste water and Carbonate Freezings - Aminopolycarboxylate, EDTA, EDA, PETA, ...
  • Waste water containing Phosphonates - Polyphosphonates

The units can be designed as batch or continuous processes. Economic data will be the base of the process applied.

In the application "electroless Nickel" not only the chelates can be destroyd but also reduced phosphorous oxides like Hypophosphite and Orthophosphite can be oxidised to  Phosphate. Phosphate can be precipitated easily. By this legal limits for P can be complied with also.
