METHOD OF CLEANING SURFACE OF OPEN WATER RESERVOIRS FROM CONTAMINATION OF OIL AND OIL PRODUCTS Russian patent published in 2016 - IPC E02B15/06 E02B15/10 C02F3/34 B01D15/00 E01H12/00 B09C1/10 

FIELD: ecology.

SUBSTANCE: method of cleaning surface of open water reservoirs from contamination of oil and oil products involves use of sorbents and oil-oxidising microorganisms, sorbent used is sawn off pine fraction 2-10 mm, placed in sorbing booms, which are arranged at selected borders localisation of oil and oil products, washed with shore edge in water mass of oil and oil products water under pressure, coastal line soil is cleaned using pine sawdust as sorbent, oil-water mixture is collected from open water surface using oil-collecting system collection. This mixture is placed in tanks or quickly deployed vessels. Collection of sorbing slick bars from surface of open water body is conducted. Sorbent briquettes are produced from saturated oil and oil products. Residual concentration of oil and oil products in treated water mass is determined, latter is compared with level of their maximum allowable concentration in water of corresponding value. In case if residual concentration level exceeding maximum allowable value further treatment of water masses is performed using microorganisms capable of destruction of hydrocarbons of oil and oil products. To do so inert loading is immersed into the water mass in form of polyethylene film for period of up to four months. During whole period temperature of water mass is maintained at level of not less than 10°C. Residual concentration of oil and oil products in water is determined with periodicity once a week. Upon reaching of maximum allowable concentration of oil and oil products level inert loading is removed from water mass.

EFFECT: simplification of cleaning.
