Ecological Method for Cleaning Oil From Lakes
A new technology developed at Tomsk State University (TSU) for cleaning oil from lakes is best suited for lakes with thick sediments, report scientists. The method allows cleaning both sediments and water, and there are no any restrictions on the depth of the pond.
The oil cleansing method was developed by TSU researchers, and it is optimal for lake ecosystems. The experiment proved that the content of oil in water wasc reduced by 35 to 40 times.
“The technology is based on flotation method,” said Danil Vorobiev, one of the authors of this development and doctor of biological sciences and director of the biological institute at TSU. “In place of oil accumulation, we perform pneumatic and mechanical action and, as a result, oil sticks to the section of the two phases—liquid and air—and rises to the surface.”
The method does not require using any chemicals and can be used in winter when vegetative processes in a lake “freeze” and interference with the underwater world is minimal.
