 Advantages
of EcoClean and EcoClean-M |
| 1.
Effective in a wide range of sites |
| Till date, EcoClean and EcoClean-M have been applied on more than 60 sites
in Japan and overseas. The unique combination of microbial nutrients
in these products stimulates a wide range of microorganisms. Therefore
we do not depend on presence, or absence of specific microbes such
as Dehalococcoides. EcoClean has been successfully applied to remediate
at least 3 sites in Japan where Dehalococcoides was not detected. |
| 2.
Cost effective and ease of application |
| EcoClean and EcoClean-M are completely water-soluble and therefore
can be injected subsurface under gravity using simple mixing
pump and tank. Under ideal hydrogeological conditions these
biostimulants can propagate for more than 10-15 m in the groundwater.
Therefore these are widely accepted by clients to apply at
active manufacturing facilities. These can be applied through
wells located 10-20 m apart at these facilities without disrupting
the day today manufacturing activities. The application does
not need the use of heavy machineries. |
| 3.
Short remediation time |
| The time taken for remediation depends on several factors
such as hydrogeology, contamination concentration and distribution,
presence of co-contaminants etc. In general results of contamination
degradation can be obtained within 2-4 months of EcoClean or EcoClean-M
application on most of the sites. As compared to traditional
techniques such as “pump and treat” which takes more than a
decade to completely clean a site, EcoClean or EcoClean-M can perform
the same job in a matter of months. That would save huge operation
and maintenance cost. Please refer to the field results for
more details. |
| 4.
Degrading high concentration |
| We have successfully cleaned several sites containing contamination
of tens of mg/L order within a span of few months, which, in
general, are thought to be difficult to degrade by bioremediation
within such a in short time. Till date, the highest concentration
of contamination completely degraded with EcoClean is 380mg/L of
TCE and 120mg/L of C-DCE. At many sites, we have witnessed
that the application of EcoClean dissolves the sorbed phase of contamination
and thereby helps increase the bio-availability of contaminants
for complete microbial degradation. |
| 5.
Ultra-Low energy requirement |
| Unlike many other technologies such as “pump and treat”,
soil vapor extraction EcoClean or EcoClean-M based bioremediation takes
a small amount of fuel/electricity. At many sites simple mixing
pump and gravity feed injection is practiced. |
