ACO StormSed Vortex - pollutant removal

From residential to industrial and infrastructure projects, the ACO StormSed Vortex removes pollutants such as floatable and sediment bound contaminants from surface rainfall. The removal of sediments from surface water is a crucial stage of a suds project, with around 75 percent of chemical pollution, such as metals and residual oils bound to sediment. 

Used either as the preliminary or independent treatment, the ACO StormSed Vortex can extend the service life of downstream products and extend maintenance intervals of downstream drainage systems. 

Unlike conventional oil separators, the StormSed is able to offer a level of treatment for the extreme rainfalls while being sized for a more typical rainfall.

StormSed in design

Boasts a variety of features to allow for an optimally designed drainage network.

• High performance: designed to remove 100% of floatables and 50% of total suspended solids, of 75-micron particles at high treatment flow rates (and up to 80% when required - contact ACO if required). 

• Wide range of flow rates: available in a wide variety of sizes to accommodate small to large projects. This includes pipe sizes to accommodate severe rainfall situations.  

• Treatment for severe rainfall: unlike conventional separators StormSed will still offer a level of treatment during severe rainfall, when designed for lower rainfalls. During severe rainfalls StormSed will capture all floatables. 

StormSed on site

When designing the ACO StormSed, a efficient installation process and easy maintenance regime for the system was of high priority:

• No manhole chamber required: comes pre-fabricated with a protective casing and can be installed as an isolated unit. This translates to a saving in total installation cost and time. 

• Compact installation: offers a significant lower footprint relative to conventional separators. This not only enables installation within a tighter space, but reduces installation cost and time.

• Simple maintenance: undertaken at ground level, accessed via a single manhole access cover using a suction hose. The majority of floatables are accessed and suctioned through the active treatment chamber. When required the sediment is also easily accessed.

SuDS mitigation indices

• Total suspended solids: 0.5

• Metals: 0.4

• Hydrocarbons: 0.5
