The diffusion of dissolved oxygen is an essential step in wet air oxidation processes. The report is an investigation of the conditions under which this diffusion step becomes a limiting factor for such processes which use an air bubble column reactor for sewage treatment. The results show that the importance of oxygen diffusion as a rate-limiting step depends mainly on reaction temperature and pressure, chemical oxygen demand, bubble diameter, air supply rate, and reactor height. The implications of these results for shipboard waste treatment processes currently being considered by the Navy are examined. Author
