PURPOSE: To perform titled dehydration with high working efficiency and easy control of concentration, by supplying sludge water into a hose-like filter cloth cylinder, and concentrating and dehydrating the same then exerting rolling and pressing force by a rolling roll to the filter cloth cylinder and squeezing out and discharging the concd. sludge.
CONSTITUTION: A discharge valve 10 is closed, a driving valve 9 is opened to feed and supply sludge water forcibly into a filter cloth cylinder 1. While the sludge water is held filled in the cylinder 1, the valve 9 is closed. Filtrate is discharged for a while through the entire surface of the cylinder 1. The valve 10 is then opened; at the same time, a rolling roll 2 is moved downward from the top end of the cylinder 1 toward the bottom end under exertion of rolling and pressing force, so that the concd. sludge is discharged by the pressing force thereof. When the discharging down to the bottom end is completed, a winder 5 is driven by a motor M1 to return the roll 2 to the top end position. If necessary, a washing water valve 11 is opened to wash the inside of the cylinder 1 with washing water after the roll 2 is returned to the top end and the pressure thereof is released.
