| description | A rotary screening device is disclosed which may be advantageously used to increase the solid content of influent. The apparatus includes a rotating cylinder having an inlet end, an outlet end and, depending on the material to be screened, a cylindrical wall formed at least partly from a screening surface, such as a woven wire mesh screen. The cylinder is journalled for rotation about its central axis, which may be either in a horizontal position or inclined up to 40 degrees from horizontal towards either the inlet or outlet end. Each end of the screening cylinder has its lowermost portion covered to restrict outward movement of the influent from the cylinder and maintain a minimum layer of retained solids therein. |
