Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method for filtering stormwater. More specifically the present invention relates to a device and a method for filtering stormwater inside a storm drain to remove pollutants from it.
  • Stormwater which also is called urban runoff, is surface runoff of rainwater, melted snow or ice, wash water or similar from different types of surfaces. Such surfaces can be parking lots, sidewalks, roofs, and similar surfaces, sometimes referred to as impervious surfaces. Water running off from such surfaces tends to become polluted by e.g. gasoline, oil, heavy metals, trash, fertilizers, pesticides and other pollutants. During rain these surfaces carry polluted stormwater to storm drains. Storm drains can be connected to a drainage system for discharge into receiving surface waters, such as a canal, river, lake, reservoir, sea, ocean, or other surface water, with or without treatment of the stormwater before discharge.
  • surface waters such as a canal, river, lake, reservoir, sea, ocean, or other surface water
  • Storm drains generally comprise a vertical pipe having an inlet, such as a horizontal grated inlet or a side inlet, being connected to a drainage system.
  • Such storm drains can comprise a catchbasin, also called sump or gully-pot, for catching small objects, such as sediment, sand, gravel, pebbles, twigs, trash and similar.
  • the catchbasin serves as a water-filled trap for trapping objects and prevent such objects from entering the subsequent drainage system.
  • catchbasins also prevent gases from the drainage system from escaping.
  • Storm water from the top of the catchbasin drains into the subsequent drainage system.
  • the catchbasins can be emptied by means of vacuum trucks at suitable time intervals.
  • An object of the present invention is to avoid the drawbacks and problems of the prior art.
  • the device and method according to the present invention result in a reliable and efficient filtering of stormwater as well as easy installation and replacement.

  • a part of the bottom portion of the filter unit, when the device is arranged in a storm drain, is arranged at the surface by means of the floating carrier.
  • the apertures in the floating carrier result in that stormwater at said surface can engage the bottom portion of the filter unit to remove pollutants accumulated at the surface of the stormwater.
  • the structure of the device results in easy installation of the device and easy replacement of the filter unit.
  • the filter unit is detachable from the carrier, wherein the filter unit can be replaced and the carrier can be reused.
  • the top portion of the filter unit can be formed with an inclined surface, e.g. by the filter unit being tapered or cone shaped, for guiding non-filterable objects to the surface of the stormwater inside the storm drain.
  • non-filterable objects such as twigs, trash, sand and similar
  • fall through the storm drain it will then hit the inclined surface and continue along therewith to the surface of stormwater and then continue further to a catchbasin in the storm drain.
  • non-filterable objects are prevented from accumulating on top of the filter unit to impede its function.
