Filter for a treatment apparatus

Abstract

A filter unit for separation of particulate matter from particulate-laden liquid, the filter unit comprising: a chamber defined by an upper axial end wall and an opposing lower axial end wall and a peripheral particle collection wall, the upper and lower axial end walls being spaced by the peripheral particle collection wall, the chamber being rotatable about an axis of rotation so as to impart rotational motion to the liquid; an inlet for delivering particulate-laden liquid into the chamber; an outlet in the upper or lower axial end wall for discharging filtered liquid from the chamber; a flow path from the inlet to the outlet; wherein the flow path includes a radial component from the inlet to the peripheral particle collection wall and an axial component along the peripheral particle collection wall.
