The invention provides apparatus for removing solids from a liquid stream, the apparatus comprising: a separating chamber (102) having a liquid inlet at an upstream end thereof, a central first outlet (136) at a downstream end of the chamber and a second outlet (138) disposed radially outwardly of the central first outlet; the liquid inlet being in communication with a source of pressurised liquid and comprising at least one angled channel (116) passing through a nozzle block (110) and opening out into the separating chamber (102); a spinner (126) rotatably mounted inside the separating chamber and having a plurality of vanes; the separating chamber (102) and spinner (126) being arranged such that, in use, pressurised liquid passing through the angled channels (116) of the liquid inlet is incident upon the vanes of the spinner so as to rotate the spinner and thereby swirl liquid entering the separating chamber to form a vortex, the pressurised liquid being the sole means of rotating the spinner, the vortex bringing about centrifugal separation of components of the liquid as it passes from the upstream end of the chamber to the downstream end of the chamber, the denser components of the liquid stream being directed out of the chamber through the second outlet (138) and lighter components of the liquid stream being directed out of the chamber through the central first outlet (136).
