Goodwin, R. W.; Gleason, R. J.

Raw scrubber sludge is difficult to transport and is mechanically unstable when disposed of in a landfill. Stabilization eliminates these problems by converting the semiviscous sludge to a soil-like material which can be transported and land disposed. Blending, forced oxidation, and fixation are commercially offered processes for scrubber sludge stabilization. Blending combines dewatered sludge with flyash. Forced oxidation uses air to produce dewatered sulfate formations. Fixation adds lime to improve the mixture's physical properties. The cost and environmental acceptability of each of these processes are compared. It is concluded that a combination of oxidized sludge and flyash allows the least cost disposal for the user. (LCL)
