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.

OXYDOLOxydol 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, 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.

BENEFITSBENEFITS

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.
