Abstract

An apparatus for partial dehydration of a sludge in the centrifugal field of a centrifuge wherein the residual moisture of the sludge is substantially reduced with a comparatively low compression of the sludge, and the non-effective cone length of the centrifuge is reduced without shortening the sludge dwell time. The invention includes an arrangement of agitator elements within the centrifugal drum, coupled with a following shearing centrifuge and decanter, the shearing centrifuge being connected at the discharge of the centrifugal drum.
