Both processes are generally applicable to organic materials. They have somewhat different advantages and disadvantages:

  • Wet air oxidation does not perform a complete mineralization. The high organic content of the effluent water will require further processing (e.g., biological treatment).

  • Corrosion is expected to be a severe problem with both technologies, requiring control by suitable choice of material and/or control of pH. Corrosion is a particular problem with supercritical water oxidation, where pH control has thus far led to plugging problems.
