Prevent 100% of combined sewer floatables and gross solids and 95% of grit and sediment from reaching the environment.
The Storm King® is an advanced hydrodynamic vortex separator and screen that delivers exceptional removal of TSS, BOD and other materials at combined sewer overflow sites, preventing damaging pollutants from reaching the environment during heavy rainfall and surge events.
A small-footprint, non-powered, low-maintenance unit with low capital and O&M costs, the Storm King® is ideal for satellite treatment at overflow sites and can reduce project costs by up to 50% compared to conventional technologies.
The Storm King® is an advanced hydrodynamic vortex separator and screen that delivers exceptional removal of TSS, BOD and other materials at combined sewer overflow sites, preventing damaging pollutants from reaching the environment during heavy rainfall and surge events.
Combining both a screen and a hydrodynamic separator, the Storm King® achieves exceptional removal of CSO pollutants, delivering 100% removal of floatables and gross pollutants and 95% removal of grit and sediment.
A small-footprint, non-powered, low-maintenance unit with low capital and O&M costs, the Storm King® is ideal for satellite treatment at overflow sites and can reduce project costs by up to 50% compared to conventional technologies.

The Storm King® delivers 100% removal in two directions of gross solids, floatables and neutrally buoyant material larger than 6 mm, and achieves 95% removal of TSS and BOD - equivalent to primary treatment.
The Storm King® incorporates both a screen and a hydrodynamic separator to ensure exceptional removal of CSO pollutants, and trials conducted in the USA at Columbus, GA and Saco, ME show that the unit can also be used to provide disinfection in 30% of the area normally required for conventional disinfection technologies - enabling the system to provide three treatment functions in a single unit.
The Storm King® is a small-footprint, non-powered, low-maintenance unit with low capital and O&M costs, and offers up to 50% project cost savings when compared with conventional technologies such as micro-strainers.
With no moving parts, no power requirements and self-cleansing components, the Storm King® is a low-maintenance CSO treatment and wastewater management solution.
Flow is introduced tangentially into the side of the Storm King®, causing the contents to rotate slowly about the vertical axis (blue arrow).
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 spiraling column, rotating at a slower velocity than the outer downward flow (red arrow). 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.
Floatables, gross solids, neutrally buoyant material: 100% of 6 mm in two directions
High rate disinfection in less than 8 minutes
Grit and sediment: 95% removal of grit 106 micron and larger can be provided; different size systems can be provided for different levels of grit removal performance.
Get high-performance, low-footprint CSO screening even under challenging overflow conditions.

In many parts of the world no regulations exist to protect the water quality and environmental integrity of rivers, and in those parts of the world where rules do exist they are often not enforced effectively or consistently.
