Redevelopment of contaminated areas by in-situ and on-site technologies
|
SGDA mbH offers a wide
range of cost-efficient on-site and in-situ methods.
Microbiological treatment, for example, can be applied on-site.
Costly transportation processes are not necessary. The treated material
can be used for profiling or similar purposes.
One possibility of
microbiological treatment of soil under buildings, supply or disposal
systems, etc., which cannot be demolished or removed and disposed of is
in-site microbiological treatment.
For this purpose, sets of
infiltration wells are constructed around the contaminated area and
microorganisms, nutrients and special oxygen donors added to the wells.
The success of treatment can be speeded up by loosening the soil
structure with air lances and blowing compressed air in the soil before
the actual treatment begins.

The landfill seepage as
well as material polluted by to BTEX and easily volatile chlorinated
hydrocarbons are treated in strip systems which are designed,
manufactured and operated specifically for each redevelopment case.
Methods involving the
immobilization of pollutants in contaminated soil and building rubble
are gaining currency due to comparatively low specific costs. Together
with the Merseburg University of Applied Technology, SGDA develops such
processes, especially for immobilizing mineral hydrocarbons and PAH
contaminated soils and building demolition rubble.
Required preliminary and
laboratory tests can be conducted in our technical laboratory in
Zella-Mehlis. In addition to the machines for preparing and mixing the
samples, we also have the analytical tools for measuring chemical and
soil-mechanical characteristics as well as elution equipment
(application of a modified trough method).
