Screening apparatus that provides improved dewatering of liquid slurries includes a plurality of spaced, ridge-shaped flow disruption elements secured to the vertical side walls of the screening apparatus and a plurality of deflector elements disposed along the back convex surface of the screen extending across substantially the entire width of the screen parallel to and in engagement with bar-shaped members forming the screen. The flow disruption elements cause the thick slurry which otherwise sluices along the side guide surfaces of the screening device without being completely subjected to the screen action to be directed or diverted inwardly towards the active surface of the screen. The deflector elements cause the thruput water flowing down the back convex side of the screen which has passed through the screen to be diverted and captured in a container underneath the screen without running the entire length of the screen and tending to inhibit the water from passing through the screen on the downstream side of the deflector. |
