OXYDOL, Treatment of soil
contaminated with hydrocarbons.
OXYDOL
A product based on specific beneficial
bacteria, enzymes, organic catalyzers,
stabilizers and accelerator elements for the
control of odors and to degrade organic
matter in earth contaminated with
hydrocarbons, restoring the soil for
productive activities while complying with all
applicable environmental regulations.
OXYDOL, Treatment of soil
contaminated with hydrocarbons.
OXYDOL
Oxydol is a biologically safe alternative for
environmental programs in areas of
petroleum exploitation, whose application
both with contaminated soil and liquid
byproducts of hydrocarbon storage tanks
(sediments) offers significant environmental
benefits and improves the condition of soil
allowing it to be used for other productive
purposes
OXYDOL, Treatment of soil
contaminated with hydrocarbons.
GOAL
Bioremediation of soil contaminated with
hydrocarbons, reducing the rate of
contamination to below the official minimum,
3000 ppm of TPH (Total Hydrocarbons Present),
controlling unpleasant odors, returning the
physiochemical condition of the soil to normal
and promoting better environmental conditions
for the area.
OXYDOL, Treatment of soil
contaminated with hydrocarbons.
PREPARATION
To produce 20 liters of concentrated liquid
OXYDOL, we have to mix 500 grams of
powdered OXYDOL with 19.5 liters of water
(free from chlorine).
OXYDOL, Preparation of the Product.
Mix 500 grams of OXYDOL with19.5 liters
of water
Forming a concentrated aqueous
solution of 20 liters of liquid OXYDOL.

OXYDOL, Applied Technology
OXYDOL reproduces native
microorganisms exponentially,
achieving a greater quantity of
microorganisms able to degrade
hydrocarbons in less time.
The excess population of native bacteria thus
created is kept alive for the time required by the
process by means of optimal conditions for them
such as the oxygenation by ploughing, humidity,
pH levels and several other parameters.
OXYDOL, Biorremediation Process
Preparation of the land where the work is to be
carried out. The area is examined and drainage,
boundaries and marking are verified, as well as the
need for impermeabilization, cleaning and levelling..
Intake, registration and listing of the afected material
and subsequent placing and distribution within the
area to be treated. Preparation of the product.
Collecting of speciments to determinal initial levels of
contamination of the soil, by means of the analysis
of Total Hydrocarbons Present – TPH.
.
OXYDOL, Biorremediation Process
Application of OXYDOL and
encapsulation of oxygen necessary for
degredation
In order to conserve optimal treatment conditions, the ground will
undergo a process of Mechanical Oxygenation, and a
process of moistening, that depends on the climactic conditions of
the area.
OXYDOL, Biorremediation Process
Taking samples to control and
monitor the process.
Soil after treatment is finalized, on
the 27th day.

OXYDOL, Treatment of soil
contaminated with hydrocarbons.
EVALUATIONS
• Analysis of TPH (Total Hydrocarbons Present).
• Design and follow-up of the protocol.
• Inspection and review of the physical condition of the
soil and the environment as regards reduction of odors.
• Advice from personnel specialized in environmental
matters.
OXYDOL, Treatment of soil
contaminated with hydrocarbons.
CONCLUSIONS
•During the process of biorremediation, the reduction of odors was
remarkable after the first 15 days.
•The rapid degradation of hydrocarbons, was evident from laboratory
analyses, results below TPH: 3000 mg/kg (ppm).
•The change in color of the soil and the change of its physicochemical
properties was 90% completed on the 27th day of treatment.
•The physicochemical propertes of the soil comply with all
requirements of the environmental authorities after the first month of
treatment.
OXYDOL, Treatment of soil
contaminated with hydrocarbons.
CONCLUSIONS
•
The inspection and design of appropriate protocols for
environmental and geographical conditions and as regards the
level of hydrocarbon contamination for the purpose of
garantizing optimal results with this technology are definitive.
•
The use of OXYDOL showed itself to be a rapid, safe and cost
effective tool with many economic benefits for the
briorremediation of soil contaminated with hydrocarbons,
recovering the land and rendering it useful for other productive
purposes.
