Advantages of OxyTek’s Chemistry
ADT Environmental brings state-of-the-art technology to our clients in many
forms. Some are equipment-related and others in the form of new technology. Our
newest treatment technology is field-proven in the United States and Canada.
We call the process “OxyTek”. The OxyTek™ process uses chemical reagents — not
bugs, as in bio treatments, or heat, as in thermal to break down TPH into its
sub-constituents.

The OxyTek
process:
 |
Eliminates environmental problems
|
|
|
Has no byproducts |
|
|
Has no emissions |
|
|
Can be more cost-effective than thermal treatments |
OxyTek has been shown to be effective for a wide range of TPH constituents.
|
 |
Due to the lack of emissions, and the fact that the treatment process does
not rely on high temperatures, most of the issues involved with thermal
treatments are eliminated (bag houses, rate of feed, massive monitoring to
control emissions, in feed rates and possible explosions etc.). In addition,
materials can be processed at a rate of hundreds of tons per hour.
The OxyTek process has shown we can take 10’s of thousands of parts per
million of TPH and reduce them to under 1000 ppm in days. And, again, for much
less than thermal processing plants.

OxyTek™S (solid) is a proprietary, patent-pending blend of nutrients and
oxidizers used for soil and groundwater contamination.
|
|
|
OxyTek ™L (liquid) is a proprietary, patent-pending stabilized oxidizer
used for in-situ soil remediation. |
|
|
OxyTek S and L safely remediate hydrocarbons, chlorinated solvents,
herbicides/pesticides, PCP/Dioxins and PCB's in-situ and ex-situ.
|
|
|
OxyTek S and L eliminate waste water and hydrocarbon odors upon contact.

H2O2 + Fe2+
→ Fe3+ + OH- + OH•
2CaO2 + 2H+ → Ca2+ (aq)
+ 2H2O2
H2O2 + OH-
→ H2O + HOO-
2H2O2 → 2H2O + O2
|
|
OxyTek maintains ideal conditions, which allows the H2O2 to completely
oxidize certain TPH contaminates and chlorinated hydrocarbons, including those
commonly found at chlorinated solvent and PCB sites, without the production of
toxic daughter products. |
|
|
H2O2 can be used to treat contaminate sources within both the saturated and
unsaturated zones. |
|
|
Rapid reaction times and high destruction efficiencies can be achieved with
H2O2, leading to significant concentration reductions at source areas and
reduced remediation costs over the life of the project.
|
|
|
Since H2O2 degrades rapidly in the environment, excess oxidant in the
subsurface does not represent an environmental impact. |
|
|
The contaminates are treated and are converted to innocuous and/or
natural-occurring compounds like water, carbon dioxide, oxygen, simple acids,
and alcohols and halides. |
|
|
OxyTek is formulated so that its oxidation reaction occurs at neutral pH of
6.5 to 7.5. |
