In the US, many utility companies are specifying forced oxidation to help to stabilize the sludge from wet-limestone scrubbers. This technique is already used in Japan and West Germany. The oxidized sludge can be more easily dewatered and thus requires considerably less disposal area than is needed for ponding the FGD sludge. The solids can also be upgraded to a commercial-grade gypsum. The processes required and the systems currently in use in Japan and West Germany are described.
