MICROBIOLOGICAL METHOD TO CLEAN FROM OIL CONTAMINATION OF WATER AND SOIL

Purpose

• cleaning water ( fresh and salty, polluted with hydrocarbons, waste storm waters ) and soils with oil contamination;
• cleaning soils on the territory of airports, moto depots, washing and gasoline stations for motor vehicles and oil and oil product storages;
• clearing and recultivation of territories of crude oil extracting and oil processing;
• cleaning intrawell equipment from wax deposit.

Description of development

Biotechnology is based on application of association of microorganisms efficient oxidizing crude oil hydrocarbons (biopreparation "Devouroil"). The special additives in a composite of a preparation make active process destruction of a petroleum. The preparation is easily applied. Oil-contaminated soil or water surface is treated with the suspended preparation by spraying with the help of any machines and assemblies and on the large areas - an aircraft.

The microorganisms, included in composite of a preparation "Devouroil", are allocated from a nature. All the strains neither pathogenity nor toxicity. Environmental and health safety of "Devouroil" preparation is confirmed by the RF Commision of Sanitary Epidemic Inspection.

Advantages of the offered biotechnology:

• high activity of hydrocarbon oxydizing of various classes;
• the efficiency of clearing of the preparation grows at the expense of action of the complex de-composition of both water-soluble and water-insolubleoil components.
• the preparation is effective actions in environment with high salinity (to 150 g/I); in a wide ranges ofpH values of environment (from 2 to 9).

Stage of development

• The biotechnology is patented ( RF Patent No 2114071).
• There is industrial manufacture of the biopreparation on stationary installation.
• The biotechnology is used in different regions of Russia and the CIS both for the purification of water reservoirs (natural and man-made) and for soil's enviromental control.
