Biofiltration definition

Biofiltration means a LID BMP that reduces stormwater pollutant discharges by intercepting rainfall on vegetative canopy, and through incidental infiltration and/or evapotranspiration, and filtration. Incidental infiltration is an important factor in achieving the required pollutant load reduction. Therefore, the term “biofiltration” as used in this Ordinance is defined to include only systems designed to facilitate incidental infiltration or achieve the equivalent pollutant reduction as biofiltration BMPs with an underdrain (subject to approval by the Regional Board’s Executive Officer).
Biofiltration means the process of passing a liquid through a biological filter that contains fixed media on surfaces which develop zoogleal films that absorb and adsorb fine suspended, colloidal, and dissolved solids and release end products of biochemical action.
Biofiltration means practices that use vegetation and amended soils to detain and treat runoff from impervious areas. Treatment is through filtration, infiltration, adsorption, ion exchange, and biological uptake of pollutants.

Examples of Biofiltration in a sentence

  • Process set-up Biofiltration (courtesy Paques) The single nitrifying sand filter unit had shown promising results and these, plus information supplied from Paques on expected BOD and solids removal, meant that the solutions team had sufficient confidence in the solution to implement it.

Biofiltration means a pollution control technique that uses living material to capture, and absorb or biologically degrade Pollutants.
Biofiltration means the simultaneous process of filtration, adsorption and biological uptake of pollutants in stormwater that takes place when shallow-depth runoff flows slowly over and through vegetated areas.
Biofiltration means the effect of vegetated treatment facilities that reduce stormwater pollutant discharges by intercepting rainfall on vegetative canopy, and through incidental infiltration or evapotranspiration, and filtration.

Biofiltration means the use of vegetation, including grasses and wetland plants, to filter and treat stormwater runoff as it is conveyed through an open channel or swale.
Biofiltration means the process of reducing pollutant concentrations in water by filtering the polluted water through biological materials.

Related to Biofiltration

  • Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.

  • Added filtration means any filtration which is in addition to the inherent filtration.

  • Irradiation means the exposure of a living being or matter to ionizing radiation.

  • Cannabis means all parts of the plant Cannabis sativa Linnaeus, Cannabis indica, or Cannabis ruderalis, whether growing or not; the seeds thereof; the resin, whether crude or purified, extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds, or resin. “Cannabis” also means the separated resin, whether crude or purified, obtained from cannabis. “Cannabis” does not include the mature stalks of the plant, fiber produced from the stalks, oil or cake made from the seeds of the plant, any other compound, manufacture, salt, derivative, mixture, or preparation of the mature stalks (except the resin extracted therefrom), fiber, oil, or cake, or the sterilized seed of the plant which is incapable of germination. For the purpose of this division, “cannabis” does not mean “industrial hemp” as defined by Section 11018.5 of the Health and Safety Code. Cannabis and the term “marijuana” may be used interchangeably.

  • Cannabinoid means any of the chemical compounds that are the active constituents of marijuana.
