Radial flow rotary screens
Radial flow screens consist of a cylinder, the periphery of which is covered with a screen mesh. Fluid enters the screen axially at one end and exits radially through the mesh. The backwashing unit is placed on the outside of the screen at the top. Influent level in the screen is maintained low enough to permit the backwash trough to clear the water. The backwash trough catches the backwash water and carries it to a drain.
