Abstract

The most important self-purification mechanism for removal of volatile compounds from rapid streams is gas transfer to the atmosphere. Various approaches to volatilization phenomena are included in a simple integrated model that considers the effect of temperature on volatilization kinetics. Thermodynamic properties related to volatilization are presented for 20 toxic priority pollutants. Only water temperature and a calculated reaeration coefficient are required for use of the model in natural streams and rivers. The proposed model was tested in a large-scale stream simulator and excellent agreement between theoretical and experimental results was obtained for two toxic compounds. As an example, the model was applied to the Rio Grande and results indicated that over 90% of the purgeable priority pollutants were removed in less than 36 hours (60 km) from the point of discharge.
