Abstract

An apparatus for separating solids and liquid mixtures such as to form concentrated sludge including a solid bowl worm centrifuge which has a slurry admission inlet and outlets for a liquid fraction and for concentrated sludge. A detector for detecting the consistency of the sludge leaving the centrifuge, a conduit for bypassing slurry being supplied from a source to the centrifuge and a control valve for controlling the amount bypassed as a function of the consistency of the sludge fraction and in some instances also a conduit for feeding a dilution liquid to the sludge leaving the centrifuge.
