<p num="1"><br/><br/><br/>A pulp digester includes a vessel having an inlet, an outlet and a wall <br/>extending between the inlet and the outlet, the wall of the vessel having a <br/>curved interior surface. The digester includes a screen assembly positioned <br/>inside the vessel adjacent to the curved interior surface of the wall for <br/>removing liquid from pulp material. The screen assembly is movable relative to <br/>the curved interior surface of the vessel wall. The digester includes at least <br/>one support element permanently attached to the vessel wall for limiting <br/>movement of the screen assembly relative to the curved interior surface of the <br/>vessel wall. In certain embodiments, the at least one support, such as a ledge <br/>permanently attached to the vessel wall, supports a portion of the screen <br/>assembly. The screen assembly may have an inner face that is concave in a <br/>horizontal direction and convex in a vertical direction.<br/>
