Brief:
| The StormScreen is a device that removes trash, debris, and large suspended particulates at high flow rates. The StormScreen consists of an inlet bay, cartridge bay, where the water is screened and discharged through flumes to the outlet bay and the outlet pipe.
The StormScreen is equipped with 20 cartridges (four discharge flumes with five cartridges per flume). The cartridges are equipped with a standard opening size of 2.4mm. The cartridges screen water by combining direct screening with the hydraulic aspects of the siphonic, radial-flow cartridge system patented by SMI. Water in the cartridge system passes through the cartridge screen and into a tube in the center of the cartridge. When the center tube fills, a float valve opens and a check valve on top of the cartridge closes, creating a siphon that draws water through the screens. The treated water drains into the discharge flume to the outlet bay, where it exits the sysem through the discharge pipe. The system resets when the cartridge bay is drained and the siphon is broken. Screened solids accumulate in the debris sump in the cartridge bay. |
