Treatment and Recovery of Road Sweeping, Gully Waste, Sand from Sewage Treatment Plants

Treatment and Recovery of Road Sweeping, Gully Waste, Sand from Sewage Treatment Plants

ADVANTAGES OF DIEMME SOIL WASHING TECHNOLOGY:

  • Recovery of a high fraction of second raw material, end of waste (> 70%)
  • Reduction of the class of risk of waste produced and consequent reduction of disposal costs
  • Volumetric reduction and concentration of pollutants
  • Reduced consumption and optimization of the use of chemical additives by monitoring and automated management of the treatment process
  • Compliance of the materials produced with the legal requirements for the classification End of Waste and product compliance with the reference technical standards
  • Closed water circuit with waste water treatment and its recirculation at the head of the plant
  • Reduction of the short-term and long-term environmental impact thanks to the saving of resources given by the re-use of secondary raw materials and the reduced use of landfill.

OUTGOING MATERIALS:

  • Gravel and sand as second raw material
  • Organic waste compostable or disposable
  • Ferrous metals sent for recovery
  • Coarse mixed wastes to be sent for disposal
  • Mechanically dewatered silt and clays recoverable
  • Clarified water treated and recirculated at the head of the system
