Preliminary Treatment
Medium gage Bar Screens
Medium gage Bar Screens range from 1 to 2 inches.
Medium gage Bar Screens will capture large debris, as well as some of the rags.
Medium gage Bar Screens can be manually raked, or could be equipped with an automatic
rake, powered by a motor driven sprocket and tracking mechanism.
The rake is parked at the top of the screen assembly, out of the wastewater when idle.
When the timing mechanism activates, the rake travels down the track and engages into
the bars raking and removing the accumulated rags and debris, depositing them onto a
conveyor or into a bin.
