EDTA wsate treatment ??
EDTA wsate treatment ??
(OP)
Lady and gentlemen,
If anyone have the experience to treat the EDTA waste by The thermal hydrolysis technology ?? We want to destroy completely the EDTA waste (about 4000 mgr/l) by The thermal hydrolysis, what is the optimal condition ? I will appreciate if someone can share with us this experience.
Thanks

Is it complexed with hazardous metal cations?
EDTA is most commonly destroyed using hypochlorite at pH 10.
Other methods (ozone, hydrogen peroxide + UV, anodic oxidation) are all slower, more complex and expensive.
I'm sure that heating would speed up all of these methods, and adding an oxidizer would lower the necessary T & P for thermal hydrolysis.
see pp. 247-254 in Handbook of Effluent Treatment and Recycling for the Metal Finishing Industry, 2nd Edn., L. Hartinger, Finishing Publications Ltd. and ASM International (1994).

Tks for your feedback, our EDTA wastes is EDTA-Ni, it is very stable ! the pilot test was ran at difference conditions (pH, oxidation (H2O2) thermal hydrolyze (high T&P), the complex EDTA-Ni was not be destroy !

Good luck.
