Abstract

PURPOSE: To secure high rate of dewatering without highly increasing dewatering pressure by adding dewatering agent to dewatered material and pressurizing to dewater.
CONSTITUTION: Sanitary waste that is pressure fed by the pressure of compressed air and dewatering agent from a supply tank 43 are supplied to a feed pipe 40, and after mixed in the feed pipe 40, they are supplied to the inside of the filter cloth 38 of the dewatering device 34. Sanitary waste supplied to the inside of the filter cloth 38 is filtered by the filter cloth 38 and discharged outside through a drain pipe 41. At this time, dewatering agent particles scattering in the sanitary waste form bridges one another, and so inside the filter cloth 38, the filling pressure of pressure fed sanitary waste becomes nonuniform. Therefore, the thickness, volume and density of the filter layer are not averaged over the whole surface area with the proceeding of dewatering, and so dewatering efficiency is not decreased although dewatering pressure is not increased.
