TLDR
In this paper, the results of a 1-hour wet air oxidation (WAO) of red water at temperatures ranging from 200° to 320°C, and P O 2 from 0.13 to 1.31 MPa, in terms of contaminant reduction and intermediate appearance were presented.Abstract:
An effective use of the wet air oxidation (WAO) process at a temperature of 340°C and 0.8 MPa P O2(25°C) to treat diluted trinitrotoluene (TNT) red water was previously demonstrated. This study presents the results of a 1-hour WAO of red water at temperatures ranging from 200° to 320°C, and P O2 from 0.13 to 1.31 MPa, in terms of contaminant reduction and intermediate appearance. Also, comparison is made between the toxicity of the raw and the WAO-treated red water on two biological systems. Results show the WAO removal efficiency to be a function primarily of temperature and, to a lesser extent, of P O2 .

Treatment of 2,4,6-trinitrotoluene (TNT) red water by vacuum distillation.
TL;DR: GC/MS results showed that most of the organic components of TNT red water can be removed by distillation, and the acute toxicity of water sample after distillation reduced 96%, compared with that of unprocessed TNT redWater.

Efficient Elimination of Organic Liquid Wastes: Wet Air Oxidation
TL;DR: Wet air oxidation is ideally suited to liquid wastes which are too dilute to be incinerated and too refractory to be handled by chemical or biological oxidation as discussed by the authors, but it relies on high tempera...
