StormFilter is a passive stormwater filtration system that is activated by the water entering a siphon. The filter consists of a tank containing a refillable filter cartridge. The water passes through the filter medium in the cartridge that captures the pollutants. This system is listed as a BAT (Best Available Technology) for stormwater treatment by the US Environmental Protection Agency (EPA).
The filter medium traps particulates and absorbs pollutants, such as dissolved metals, nutrients and hydrocarbons.
StormFilter is available in 2 different configurations: with tanks (built on-site or prefabricated), or drains with filter. The prefabricated and linear tanks and the drains with filter feature “standard” tanks for ease of design and installation, while the built on-site tanks are customised according to need for significant flows. These filters are usually installed underground but they can also be placed above ground.
The cartridge manufactured by Stormwater 360TM is the core of the StormFilter system. The possibility of choosing the filter medium according to the site requirements and the siphon passive functioning maximise its filtration effectiveness and life, making StormFilter one of the most important technologies for stormwater treatment currently available on the international market. StormFilter consists of three compartments: a pre-treatment compartment, a filtration compartment and an outlet bay. StormFilter cartridges are fitted inside the central compartment of the filtration tank.
