Contaminated soil processing includes the following:
​
-
Hydraulic erosion of stabilized contaminated soil for non-contact transport of an aggressive medium OR operate with liquid active silt, i.e., taken directly from pipe or by using fecal pumps.
-
Transport of pulp from a storage tank.
-
Spinning on drum filters, reducing humidity to 60-80%.
-
Mixing watered soil with mixture of sorbent consisting of natural minerals and acids. Also, when mixed with a solid sorbent, heating and slight cavitation take place, as well as pasteurization (80-85 gr/C), and chemical. Etching of pathogenic microflora.
-
Mixing the mixture with the sorbent, on the same aggregate. Disintegration and neutralization.
-
Granulator - Extruder (spinning under the press) + vacuum evaporator. Getting wet granules.
-
Encapsulation (dusting) of wet granules by dry sorbent. Contact dyring of granules and cementation of sorbent is a barrier for fixing odors.
-
Infra-red drying of granules and packaging in vacuum bags for sale or bulk in the fields.
​
As the result, the hazard class is reduced. The received product may be used as a reluctant for spent quarries, as well as for the biological stage of reclamation of waste solid waste landfills, and in may other instances.
