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
