- The screen modules are installed horizontally onto the storm discharge weir.
- Use of horizontally configured screens (as opposed to vertical screens) ensures that all flows, high or low, are screened with minimum velocities through the screen.
- The entire flow is in contact with the screen, so that the perpendicular flow path screens more efficiently.
- Horizontal orientation assures equal loading across the surface and thus symmetrical distribution of forces on the cleaning rakes. This minimizes jamming and breaking of comb tines.
Raked Bar Screen
The Raked Bar Screen is an efficient, reliable and cost-effective screening system for large combined sewer overflows (CSOs). It incorporates a horizontal fixed stainless steel bar-rack and a TIVAR* screen comb. The bars are continually raked by the hydraulically driven comb assembly. Maintenance of the Raked Bar Screen is minimal, and can be performed from the top/clean water side of the screen.
