Preliminary Treatment
Step Screens
Step Screens provide two sets of fine screening that are ½ to ¼ inch.
The two sets of screens operate constantly.
The two screens intermesh with each other and are self-cleaning.
The two sets of screens are configured like stair steps, slowly moving the captured
debris up to the top of the mechanism where it is deposited onto a conveyor or
dumpster.
