Russian scientists have created a "devourer" of oil in the wastewater
Scientists of the Siberian Federal University (SFU) has created a special sorbent for wastewater treatment. As explained in the press service of the University, a new sorbent based on live bacteria has the property of bio-oxidation and is able to digest components of petroleum products. This eliminates the ingress of wastewater into natural water bodies. The study is published in "IOP Conference Series: Materials Science and Engineering".
According to experts, today the technical system wastewater of many industrial enterprises, including oil refineries, need to be improved. Installed at the enterprises of oil removers designed to separate and retain hazardous pollutants, working an average of 30% of the declared efficiency, many toxicants get into the environment and cause significant environmental damage.
The study was conducted on the example of the washing of the waters of the thermal equipment of the Krasnoyarsk TPP-2 (one of the largest thermal power plants in Siberia). Scientists have identified a core group of contaminants (silicone oil) and split the long polymer chains into short fragments using cavitation in which a continuous stream of liquid is broken by the bubbles or cavities filled with steam.
Then short-chain contaminants was subjected to a special sorbent that contains oil-oxidizing strain of culture.
According to her, the sorbent analogs (Unisorb-Bio, C-Verad), but the product developed by the scientists of Siberian Federal University, has a different mineral or organic base. A new biosorbent is a small granule, easy to use on an industrial scale.
As scholars have noted, the sorbent operates in a wide temperature range, and has already undergone pilot plant testing at the enterprises of the city Kodinsk (Krasnoyarsk territory). Currently, the University has received an order from a company that is ready to engage in the production of an innovative product in large volumes.
