Storm Pollutant Removal

Primary, Secondary and Tertiary Water Treatment

The ACO StormSed range enhances a SuDS network by removing pollutants from stormwater before it leaves the site. Ideal for areas with limited space, StormSed systems provide compact, low-footprint solutions capable of managing large surface areas. With a focus on streamlined design and installation, the range offers various sizes to meet diverse project requirements. Each system comes in a pre-fitted chamber, that is easy to access for maintenance.

Treatment by Vortex Separation

ACO StormSed Vortex

The ACO StormSed Vortex is an advanced hydrodynamic separator that removes sediment bound contaminants. Its design enables removal of pollutants by means of settlement and the capture of floatables.

The ACO StormSed Vortex is available in a range of sizes to accommodate small to large sites and can be custom made for demanding installations.

The ACO StormSed Vortex retains solid pollution and oil. It also forms part of the SuDS management train as it removes over 50% of fine Total Suspended Solids as well as sediment bound metals and hydrocarbons.

Treatment by Filtration

ACO StormSed Filter

The ACO StormSed Filter is a multi-process system that combines four crucial processes – filtration, sedimentation, adsorption, and precipitation – which enables the filtration of highly contaminated stormwater.

The filter media contained in the ACO StormSed Filter retains small size particles without clogging, oil and floatables, and dissolved pollutants. It is available in a range of sizes to accommodate small to large sites.

The high level of treatment of the ACO StormSed Filter ensures that over 90% of Total Suspended Solids, as well as key pollutants such as Zinc (Zn), Lead (Pb), Copper (Cu) are removed from surface water, and retained within the system.
