The drain with cleaning function has several advantages over other systems.
The treatment of the water takes place directly under the surface of the terrain, therefore the system is simple to inspect and maintain. The filter material is not placed loose in the channel, it is contained in cushions. These are simple to remove and clean. According to the building authority approval the filter cushions only have to be replaced after 10 years.
The filter system removes pollutants such as heavy metals, mineral oil hydrocarbons and polycyclic aromatic hydrocarbons from the stormwater.
Apart from that it binds nutrients such as phosphates.
The combination of solids separator and
filter
works both on particles and on dissolved water
ingredients. The treatment plant can be used with
traffic areas such as car parks and roads with all
volumes
of traffic as well as industrial areas. Stormwater
run-offs can be cleaned to the extent that they
can be discharged into surface waters or the groundwater.
The modular design allows use in virtually all catchment
areas.
Maintenance is straightforward and can be carried
out by your own personnel. No special equipment is
necessary.
