Treatment of refractory nano-filtration reject from a tannery using Pd-catalyzed wet air oxidation

- Catalytic wet air oxidation of refractory organics in NF-reject.
- Removal of potential EDCs after CWAO.
- Mineralization higher with Pd/AC compared to Pd2+ and without catalyst.
- Pd catalyst stable under CWAO treatment, graphitization of support observed.
