How it Works
Flow is introduced tangentially into the side of the Storm King^® causing the contents to rotate slowly about the vertical axis.

The flow spirals down the perimeter allowing the solids to settle out. This process is aided by rotary forces, shear forces and drag forces at the boundary layer on the wall and base of the vessel.

The internal components direct the main flow away from the perimeter and back up the middle of the vessel as a broad spiralling column, rotating at a slower velocity than the outer downward flow. By the time the flow reaches the top of the vessel, it is virtually free of settleable solids and is discharged to the outlet channel. Prior to discharge, the overflow passes through the Swirl-Cleanse™ screen.

The Swirl-Cleanse™ screen captures all floatables and neutrally buoyant material greater than 6 mm. The air regulated siphon provides an effective backwash mechanism to prevent the screen from blinding.

The collected solids and floatables are then discharged by gravity or pumped out from the base of the unit to the sanitary sewer.

Typical Design Loading Rate: 25 to 100 l/s/m².
