" A 3-month field demonstration study was conducted on the hyperbaric oxyozosynthesis process for sludge conditioning and stabilization at the Monroe, Michigan, Metropolitan Area Wastewater Treatment Facility. The process involves contacting sludges, under pressure and at reduced pH of 3 to 4, with oxygen and ozone for periods of up to 3 hours. The primary objective of this study was to evaluate the process with respect to its effect on sludge dewaterability, as measured by the Buchner funnel specific resistivity test. The process had been demonstrated previously for sludge stabilization measured by bacteria destruction. The present study confirmed that advantage, also the ability to reduce odors. The findings of the present study, however, indicate that the oxyozosynthesis process did not improve sludge dewaterability, but actually decreased dewatering characteristics somewhat. Also, the oxyozosynthesis process did not achieve any significant reduction of sludge volatile solids or total chemical oxygen demand." |
