Stormwater treatment at Arlanda Airport
De-icing agents from Scandinavia's largest airport reach a nearby lake via stormwater. Aeration and barrier walls create the treatment zones that break them down.
The customer's challenge
At Arlanda Airport, de-icing agents are released into a nearby lake via stormwater. Left untreated, the organic load from glycol-based agents consumes oxygen in the receiving water and degrades the lake environment.
The solution
Eden Aquatech's solution combines oxygen supply with barrier walls. The aerators and the controlled flow path create both an aerobic and an anaerobic zone — the sequence needed to break down the de-icing agents biologically before the water continues into the lake.
Products used in this project

Floating Walls
Control flows and create treatment volumes in ponds. Floating walls eliminate short-circuit flows and give every treatment stage the retention time it needs.
