Contaminated soil and groundwater remediation are becoming important activities in industrial countries specially in dismissed industrial area where soils and groundwater have been polluted in years of operation with low attention to the environmental effect of certain production or working procedures.
The cleanup of environmental pollution involves a variety of techniques, ranging from simple washing processes to advanced engineering technologies.
STC engineers are continually developing and adopting new technologies in attempts to cope with the challenges and strategies for cleaning up different types of contaminants, mainly heavy metals and persistent organic compounds and improve the decontamination processes.
To achieve a good efficiency of remediation, new techniques or even new technologies may be combined with more consolidated technologies, as a treatment train, thus improving the overall performances or overcome limitations.
Soil washing is a remediation process for excavated soils purification from contaminants via water or other solvent treatment.
The plants include soil feeding system, washing in rotary reactors, solid separation by filtration, treatment of the resulting waters.
The plant can be realized in “mobile” version so that it can be easily moved from one site to another.
Associated with soil washing plant, there is always the need to treat the resulting water as well as the ground water: in this case all the treatment process included in STC portfolio may be applied and integrated depending on type of contamination.
