Higher fibrous material in sludge means higher dehydration performance of the Shaft Sliding Screw Press Dehydrator used in the Value Sludge System. In Japan’s night soil treatment plants, fibrous debris contained in the night soil brought in was screened prior to sludge dewatering and then was independently disposed of. However, the System enables the fibrous debris to be dewatered together with sludge and successfully omit the screening system which contributes to the reduction of the capital cost.
