Russian scientists have learned to cleanse reservoirs from oil using bacteria

According to the authors of the study, wastewater treatment systems at industrial enterprises, in particular at

refineries are outdated. They can retain an average of 30% waste of their stated efficiency.

We decided, by means of physical and chemical analysis, to compile a dossier on oil products from effluents from various enterprises and to select sorbents capable of trapping toxicants that had not previously fallen into traps.

To test the effectiveness of a newmethod, scientists have identified the main group of pollutants (organosilicon oils) and divided long polymer chains into short fragments using cavitation action, in which a continuous stream of liquid is bursting with bubbles or cavities filled with vapor.

Then, the short-chain contaminants were exposed to a special sorbent containing oil-oxidizing strain cultures.

According to the researchers, the new development is effective even in a wide temperature range and has already passed semi-industrial tests at enterprises in the Krasnoyarsk Territory.

The university has already received an order from a company that is ready to engage in large-scale production of an innovative product.
