Vladimir Shtepa, Head of the Industrial Ecology Department of the Belarusian State Technological University (BSTU), presented the results of the joint work of Penza State University and BSTU on the project "Development of wastewater treatment technology using ferrates" at the III International Specialized Environmental Exhibition "ECOLOGY EXPO-2025". The event was held from August 19 to 21 in Minsk.

From the side of Penza State University, the project is supervised by Sergey Kireev, Doctor of Engineering Sciences, Professor, Dean of the Faculty of Industrial Technologies, Power Engineering and Transport of the Polytechnic Institute. 

The exhibition has become a showcase of innovative solutions in the field of environmental protection.

Delegations from Russia, Kazakhstan, Uzbekistan, Kyrgyzstan, Brazil, Mongolia and China took part in it. It brought together representatives of government bodies, heads and specialists of Belarusian and foreign companies, experts from the environmental community, leading scientists and developers.

The work was carried out in nine areas, where organizations presented the best available practices, successful developments and promising initiatives. Each area was accompanied by a large-scale display for a visual presentation of implemented projects and the latest technological trends.

The participants discussed key issues of the development of the "green" economy, touched upon the topic of exchanging best practices. The exhibition demonstrated achievements in the field of environmental protection and rational use of natural resources. 

Penza State University fruitfully cooperates with Belarusian State Technological University. One of the areas of work is the development of a reagent-free technology for water treatment and wastewater purification.

At the plenary session of the II scientific and practical conference "On the exchange of experience and practices in implementing projects and programmes for the purpose of developing Belarusian-Russian cooperation in the field of protection and rational use of transboundary water bodies", Doctor of Engineering Sciences Vladimir Shtepa presented the results of the study.

Scientists from PSU and BSTU propose using an electrochemical module for generating ferrates in the general scheme of wastewater treatment. This technology is capable of purifying contaminated liquid from various compounds without reagents. The use of ferrates combines the functions of a coagulant, oxidizer, and disinfectant. The proposed method is not only environmentally friendly, but also does not cause corrosion of process equipment.

The proposed method of wastewater treatment has been implemented at a meat processing plant in the city of Pinsk (Republic of Belarus) and at several treatment facilities of city water utilities. During the experiment, contaminated water was pumped using a circulation pump through electrochemical modules.

The experiments have shown that the method proposed by the collaboration of Russian and Belarusian scientists achieves the required indicators for subsequent disposal and use of purified water. At the same time, it is more economical, and also breaks down complex pollutants and does not leave reagents in the water.

Joint work on the project continues.
