tion of use with municipal sewage sludge was completed in 1985.

Possible corrosion problems must be examined when SCWO is considered. High-temperature flames observed during SCWO may present additional equipment problems in both surface and subsurface SCWO systems. There is some concern that these flames will cause hot spots which could weaken SCWO vessels (DOE 1991).

Status. Demonstration of use with municipal sewerage sludge completed in 1986.
