ABSTRACT:
The screen comprises a set of spaced parallel grating bars set at an inclination of about 35 degrees. The grating bars retain solids carried by the water flowing between the bars. These solids are automatically pushed down the bars and away into a collecting trough transverse to the bars by water streams flowing within longitudinal grooves formed from the top of the bars. The cross-sectional area of each groove decreases from the upper end to the lower end of the bar, so that the water accelerating down the bar grooves will constantly fill the same.
