Enhanced stormwater treatment:

• Treatment of polluted runoff from roads, car parks, industrial sites and airports

• Highest structural loading capacity

• Close to the surface, with low head loss

• No loose filter media

• Media exchange interval > 10 years

• Connectable surface area 20 to 150 m2/m

• General technical approval by DIBt

Decentralized stormwater treatment is state of the art because it reduces the costs for urban drainage by using source control. The linear filter channel has numerous advantages in comparison with other systems. The treatment takes place directly below the surface, it is easy to inspect and maintain. There is only low head loss. Filter media is kept in bags, there is no loose material in the channel. Filter media has to be replaced after at least 10 years. Highest loading capacities allow to install the system in nearly any situation. The filter media removes pollutants like PAH ́s, hydrocarbons and heavy metals. Furthermore it binds phosphorous and ammonium from stormwater runoff. The two step treatment train separates solids and dissolved substances. The system is ideal for car parks, roads, industrial areas and airports. Highest pollutant levels in storm- water runoff can be reduced to acceptable loads for groundwater and surface waters. The modular design allows the adaption to nearly any site condition.
