TI  - Wet oxidation lumped kinetic model for wastewater organic burden biodegradability 
      prediction.
PG  - 3335-9
AB  - In many cases, treatment of wastewaters requires a combination of processes that 
      very often includes biological treatment. Wet oxidation (WO) in combination with 
      biotreatment has been successfully used for the treatment of refractory wastes. 
      Therefore, information about the biodegradability of wastewater solutes and 
      particulates after wet oxidation is very important. The present work proposes a 
      model that can describe the oxidation process via organic concentration 
      characteristics such as chemical oxygen demand (COD), biochemical oxygen demand 
      (BOD), and immediately available BOD (IA BOD) and so can allow the prediction of 
      biodegradability (i.e., BOD/COD ratio). The reaction mechanism includes the 
      destruction of nonbiodegradable substances bytwo pathways: oxidation to carbon 
      dioxide and water and oxidation to larger biodegradable compounds with their 
      further degradation to smaller ones measured via IA BOD. The destruction of small 
      biodegradable compounds to end products is also included in the model. The 
      experiments were performed at different temperatures (170-200 degrees C) and 
      partial oxygen pressures (0.5-1.5 MPa) in a batch stainless steel high-pressure 
      autoclave. The model of concentrated thermomechanical pulp circulation water was 
      selected for the experiments. The proposed model correlates with the experimental 
      data well and it is compared with other WO models in the literature.
