This paper report the actual performance of the shaft sliding type screw-press dehydrator enables low sludge moisture. In the 16 year of the Heisei era, as for the Ministry of the Environment, the combustion improver technology was admitted to the new recycle technology. The combustion improver means the dehydration sludge by which about 70% of water content was dehydrated, and it doesn't require supplement fuel when burning up at refuse incinerator plants. We achieved the low sludge moisture by dehydrating human waste carried in the treatment plant as well as excess activated sludge together, because while dehydration is difficult for the excess sludge, the human waste is capable of dehydration. Previously, when low sludge moisture dehydration was performed by a screw-press-dehydratoz the performance was difficult because sludge was blocked in a dehydrator On the other hand, the shaft sliding type screwpress dehydrator could settle this problem because to possess the mechanism that shaft slides. This dehydrator has five cases of operation good record of performance by fiscal year 2007, by the all cases.
