What to do with sludge? This is a key question in the City of Orlando, as well as many other municipalities around the country, and much of the world. For more than twenty-five (25) years, the City has produced and land applied Class B residuals. We know the future will require a change away from our reliance on land application of Class B residuals. Numerous issues are currently impacting the City's land application program … 1) lack of reliable wet weather application sites, 2) restrictive Local Permitting requirements and new fee's related to land application sites, 3) dwindling availability of qualified, responsive contract haulers, 4) a significant decrease in Class B land application sites in rural agricultural communities surrounding Orlando, similar to many counties and regions across the country.

The curtain is falling on land application of Class B residuals; we all need to prepare for the inevitable! The focus of this paper is to present an overview of a new and innovative sludge oxidation process currently being refined and improved at the City's Iron Bridge Regional Water Reclamation facility … Supercritical Water Oxidation.
