Definition von point source im Englisch Englisch wörterbuch: a source of pollution, radiation, waves, fluid or other substance that has one specific location (and negligible physical extent, distinguishing a point source from other source geometries). In simulations they can often be approximated using mathematical point sources; the abstract concept of a singularity emitting a flux or flow. A source with infinitesimal dimensions in space; 1) A stationary location or fixed facility from which pollutants are discharged 2) Any single identifiable source of pollution, e g , a pipe, ditch, ship, ore pit, factory smokestack, etc; A stationary location from which pollutants are discharged It is a single identifiable source of pollution, such as a pipeline or a factory POU-treatment Point-Of-Use treatment Water treatment at a limited number of outlets in a building, for less than the whole building Pollutant A contaminant at a concentration high enough to endanger the life of organisms POP's Persistent Organic Pollutants, complex compounds that are very persistent and difficultly biologically degradable; a spatially constricted by concentrated source (especially of radiation or pollution); Any discernible, confined, and discrete conveyance, including, but not limited to, any pipe, ditch channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or other floating craft, from which pollutants are or may be discharged; A source, especially of pollution or radiation, occupying a very small area and having a concentrated output; A point source is simply described as a discrete discharge of pollutants as through a pipe or similar conveyance (e g , a ditch) A technical definition exists in federal regulation at 40 CFR 122 2; a source of pollution that is point-like in nature An example is the smoke stack of a coal-fired power plant or smelter See source; Any discernible, confined, and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fixture, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel, or other floating craft from which pollutants are or may be discharged; A stationary location or fixed facility from which pollutants are discharged; any single identifiable source of pollution; e g , a pipe, ditch, ship, ore pit, factory smokestack; A stationary source or fixed facility from which pollutants are discharged Compare non-point source; Pollutant loads discharged at a specific location from pipes, outfalls, and conveyance channels from either municipal wastewater treatment plants or industrial waste treatment facilities Point sources can also include pollutant loads contributed by tributaries to the main receiving water stream or river; A stationary location or fixed facility from which pollutants are discharged; any single ide- ntifiable source of pollution; e g , a pipe, ditch, ship, ore pit, factory smokestack; a pollutant source that can be treated in a dispersion model as though pollutants were emitted from a single point that is fixed in space Example: the mouth of a smokestack Compare area source and line source; A specific source of air pollution; A discernible, confined and discrete conveyance including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, vessel or other floating craft, from which pollutants are or may be discharged This term does not include return flows from irrigated agriculture; An idealized discrete source of radiation that subtends an infinitesimally small angle; Discharges to water that originate from a specific location, such as a pipe or open channel that carries wastewater from sewage treatment or industrial process plants, or a stack from a power plant; A source at a discrete location such as a discharge pipe, drainage ditch, tunnel, well, concentrated livestock operation, or floating craft; of readily degradable organic material (pollution), (2) from the area of the discharge, and (3) from some distance downstream from the discharge, plotted by sample location The amount of dissolved oxygen is typically high upstream, diminishes at and just downstream from the discharge location (causing a sag in the line graph) and returns to the upstream levels at some distance downstream from the source of pollution or discharge; A stationary location or fixed facility from which pollutants are discharged; any single identifiable source of pollution, e g , a pipe, ditch, ship, ore pit, factory smokestack; Any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharges This term does not include return flows from irrigated agriculture or agricultural storm water runoff; A stationary location or fixed facility such as an industry or municipality that discharges pollutants into the air or surface water through pipes, ditches, lagoons, wells, or stacks - a single identifiable source such as a ship or a mine; Source of pollution that originates from a single point, such as an outflow pipe from a factory; A single isolated stationary source of pollution; A stationary location or fixed facility from which pollutants are discharged or emitted Any single identifiable source of pollution, such as a pipe or factory smokestack; A pollution source that has a single point of origin or is introduced into a receiving stream from a specific outlet Wastewater treatment plant outfalls and CSO points of discharge are typically point sources of pollution
point sources: plural form of point source
point-source: discharge a discharge from a specific and identifiable source, onto or into land, air, a water body or the sea
point-source: Most multi-unit loudspeakers try to approximate a point-source Think of a pebble dropped into the water and the expanding wave pattern away from impact Obviously it is difficult to integrate multiple point-sources into a truly coherent expanding wave The best designs do quite well with careful driver engineering and crossover development
