A screen for separating solids and liquids is formed from parallel strips of wedge wire or similar material into a substantially cylindrical two-sided enclosure in a generally C-shaped profile. Unfiltered liquid containing solids contacts the screen surface on both the convex and concave sides of the C-shaped enclosure. The unit may be placed in a vessel adapted to accommodate two such C-shaped devices in concentric relationship. The vessel may function similar to a candle filter, or a more conventional flow may be used.
