| Abstract |
The overall objective of the study was to provide plant-scale operating data on the wet-oxidation of municipal wastewater sludge utilizing the Vertical Reaction Vessel System and the effect of the return flow from the wet-oxidation process on the operation of the wastewater treatment plant. The Vertical Reaction Vessel System consists of a series of long concentric tubes placed in the earth using conventional oil field technology. Vertical construction produces a high hydrostatic head at the bottom of the system. The high pressure prevents boiling at temperatures of 250 degrees or higher required for wet-oxidation. By utilizing hydrostatic pressure, the only pumping required is that to overcome frictional losses. At temperatures above 260 degrees C total chemical oxygen demand reduction of about 80% and total volatile solids reductions of over 90% were consistently achieved. |
