The Baioni Environment Division designs, manufactures and erects soil washing plants for the remediation of soils contaminated by different types of contaminants: heavy metals, hydrocarbons, pesticides, etc. Soil Washing installations are made for the treatment of contaminated soils in order to recover the valuable part which is identified as the alternative resource to reduce the need for new quarries and landfills.

SOIL WASHING PLANTS FOR EXCAVATED SOIL
As each plant is made to measure according to characterization of soil to be reclaimed and with the intent to give customers the best technical and economic solution, Baioni Crushing Plants designs soil washing plants on data provided by laboratory tests that our partner companis carry out on significant samples of soil. These projects require an intense and integrated approach, combining civil engineering, hydrogeology and environmental technology. 

PROCESS 

• escavation and stock-piling of contaminated soil. 
• separation of large sized rubble. 
• eventual soil/aggregate crushing. 
• treatment of decontamination by mechanical attrition and washing enhanced with “extraction agents”. 
• final classification. 
• sludge treatment (dehydration). 

MAIN COMPONENTS 

• Dosing hopper with control grid 
• Crushing unit (crusher) if necessary
• Washing drum
• Vibrating screen with washing system
• Fines recovery units with hydrocyclone
• Attrition cells/scrubbers chambers
• Vibrating dewatering screen
• Clarification plant with thickener
• Sludge dehydration system
• Water treatment plant and chemical-physical
