Non-point Source Pollution Reduction Wetland

Initial rainfall reservoir is arranged to collect all of the high-concentration initial rainfall runoff and always treat
pollutants under the identical operating conditions
  • Flexible operation regardless of rainfall intensity, rainfall characteristics, and rainfall frequency
  • Efficient operation of purification wetland, high-efficiency treatment possible
High-efficiency eco-friendly purification wetland that overcomes the shortcomings of non-point resource pollution
reduction technology of natural type and device type
  • Expansion of field applicability for urban non-point source pollution reduction wetland with less than 1/5 of the site area required compared to general constructed wetland purification technology
  • High efficiency purification technology capable of maintaining over 80% of BOD removal efficiency at all times
  • Semi-permanent purification wetland that does not require replacement of filter media, providing the highest maintenance efficiency
  • Establishment of regular support system for maintenance of 공법사
Can be used simultaneously as polluted stream purification wetland and lake water purification wetland
  • Rainy day: Non-point source pollution (initial rainfall) purification wetland
  • Bright day: Polluted stream purification wetland, lake water purification wetland, eco-friendly ecological wetland park
  • 비점오염저감시설

SNR Process Application Examples of Non-point Resource Pollution Reduction Wetland
  • Urban non-point source pollution reduction wetland
    • Initial rainfall treatment for roads, parking lots, etc.
    • Creation of ecological parks and green spaces in the city center
  • Water supply source protection area, non-point source pollution reduction wetland in farming and fishing village areas
    • Treatment of farmland, forest rainfall runoff, etc.
    • The role of a buffer and purification zone to prevent direct inflow of non-point source pollutants into water supply sources
    • Creation of high-efficiency constructed wetlands in the waterfront area and providing habitat for animals and plants
  • Non-point source pollution reduction wetland such as golf courses and amusement parks
    • Establishment of a water circulation system using treated water in connection with ponds, etc.
    • Treated water can be used for various reuses such as landscaping and cleaning
