TOMSK, Oct 6 – RIA Tomsk. Scientists of the Biological
Institute of Tomsk State University (TSU) during a trip to Latvia and Lithuania
demonstrated their Aeroprobe technology, created to clean bottom sediments of
reservoirs contaminated with oil and oil products. About the results of the
presentation – in the review of RIA Tomsk.
Earlier it was reported that TSU scientists will hold
an Aeroprobe demonstration in the port of Riga, which cleans the bottom
deposits of reservoirs from oil and oil products: the complex supplies a
water-air mixture to the bottom of the reservoir, as a result, bubbles form,
oil sticks to them and rises to the surface, and it is collected by other
It was also reported that Aeroprobe passed an
examination in 2019 to create a startup in the European Union – this is how
PurOceans Technology company appeared. The startup was created with the
participation of scientists from TSU, the Latvian company
"Commercialization Reactor", which promotes innovative products from
Russia and the CIS countries, and European entrepreneurs.
Between Latvia and Lithuania
Pilot tests of Aeroprobe were carried out in the port
of Riga (Latvia), in the port of Klaipeda (Lithuania) – a survey of the bottom,
according to the TSU website on Wednesday.
According to the press service of the university,
there was more interest in TSU technology than expected. The management of the
Riga Free Port, local journalists and representatives of private oil refining
companies arrived to see how Aeroprobe works. The Aeroprobe team met with local
environmentalists in the port of Klaipeda who conduct state monitoring of

"All reservoirs are unique, each has its own
"nature" of pollution. The port of Riga has historical pollution,
where bottom deposits are represented by a layer of organomineral deposits
impregnated with oil products. Aeroprobe technology has proved its
effectiveness when working in such conditions, demonstrating high cleaning
efficiency," Danil Vorobyov, director of BI TSU, said in a statement.
According to him, the extraction rate of oil pollution
amounted to 12.5 tons per hectare of bottom in the port of Riga. Foreign
participants in the presentation noted the environmental friendliness and
effectiveness of the approach developed at Tomsk State University.

One of the main advantages of Aeroprobe technology is
its high efficiency with 100% environmental friendliness. Cleaning of bottom
sediments takes place without the use of "chemistry" and excavation
of bottom sediments.
This innovative approach is based on physical
principles: the rise of hydrocarbons is carried out due to the ability of oil
hydrocarbons to adhere to the separation of two phases – air and liquid. This
process takes place using a special installation developed and patented by TSU.
Now such technologies are especially in demand, as they contribute to the
restoration of the environment and the sustainable development of the planet.
"Living organisms, plants and algae that are at
the bottom of contaminated reservoirs are part of the oxygen production cycle.
If reservoirs accumulate pollution from oil and plastic, this creates a thick
layer that prevents the production of oxygen. Dead zones - without oxygen – are
formed in the water," Alena Stepanova, general director and co-founder of
the PurOceans company explains.
According to her, Aeroprobe technology allows to
completely remove this layer and restore the aqueous environment.
Aeroprobe goes abroad
As the TSU website reported, to date, the PurOceans
has received 100 thousand euros as a pre-seed and seed investment from the
Commercialization Reactor. To further develop technology, scale and open the
research and development center of the company requires about 1.5 million
"PurOceans is looking for funds, in particular
applications have been made for a Norwegian grant and a Horizon grant. Now
PurOceans is working to ensure that the technology and device for cleaning
bottom sediments work completely on solar energy in 2022, so they will be
completely environmentally friendly," the report said.
