Soil washing plant 🌱 Dekonta

Soil washing plant

The SWP-20 soil washing plant is used to decontaminate soils and wastes containing toxic substances. In soils, the contamination is usually bound to the surface of the particles and is therefore concentrated in the fine-grained fraction.
Therefore, the goal of the washing technology is to separate the fine-grained fraction (in the form of sludge) from the material being processed, thereby removing the vast majority of contaminants. Separated sludge containing higher concentrations of contaminants is usually characterised as hazardous waste and must be managed accordingly.

Conversely, washed soil (or other material - e.g. demolition waste) free of contamination can be used e.g. as backfill material.

Description of technology

The capacity of the SWP-20 line is approximately 20 tons of soil per hour and depends on the characteristics of the materials to be processed. Our plant is mobile and most of its parts are integrated into 5 standard shipping containers. The layout of the line can be adapted to the customer's space requirements. The washing plant consists of the following main parts:

Soil feeding unit comprising a soil feeder bin (5 m3), a scalping vibrating screen, a belt weight feeder and a belt conveyer
Soil washing unit comprising a drum washer (diameter 2,3 m, length 5,5 m) and a trommel screen (size 5 mm)
Classification unit comprising a spiral classifier (diameter 0,5 m, length 4,0 m), two hydrocyclones (diameter 150 mm), a slurry tank and a slurry pump
Sludge thickening unit including a sedimentation tank (20” container), a bottom sludge scrapper, sludge removal system and two pumps
Sludge dewatering unit comprising a filter press, equipment for chemicals preparation and dosing, filter cake discharging and collecting equipment (the unit comes in two 20” containers)
