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
