Start-up and commissioning tests of the Biosfera innovative complex of biological treatment facilities have started at the Gazprom Neft Moscow Oil Refinery.
Moscow Mayor S. Sobyanin and Chairman of the Board of Gazprom Neft A. Dyukov visited the new production facility of the Moscow Refinery.
Completion of the construction of the "Biosphere" is the final stage of work to minimize the impact of the enterprise on the aquatic environment as part of the program of environmental modernization of the Moscow Oil Refinery.
Moscow Mayor S. Sobyanin stressed: “The Moscow Refinery is implementing a large-scale environmental program, as a result of which the level of the enterprise's impact on the environment should decrease by about 4 times. Today the next stage of modernization has been completed. Wastewater treatment facilities "Biosfera" have been built, which will ensure the most complete purification of wastewater. In addition, the company will reduce water intake from the Moskva River by 2.5 times due to the reuse of treated water within a closed cycle. This is good news for all residents of the capital and the Moscow region. Especially for those who live near the plant and go for walks in the parks located in the lower reaches of the Moskva River.”
Indeed, a unique technological system developed by domestic engineers will complete the formation of the plant's water treatment complex and increase the efficiency of wastewater treatment to 99.9%. Besides:
75% of the water used will be returned to the production cycle.
The consumption of fresh river water will decrease by 2.5 times and the load on the city's wastewater treatment facilities of Mosvodokanal will be reduced.
These are grandiose indicators that directly affect the growth of the environmental friendliness of the enterprise's water consumption.
A. Dyukov, Chairman of the Management Board of Gazprom Neft, noted: “The Moscow Refinery is by no means the only petrochemical enterprise operating within the boundaries of Moscow, but today it is the undisputed leader in terms of the scale of changes and the dynamics of production modernization. The projects that Gazprom Neft is implementing at the Moscow Refinery address the company's priority tasks of minimizing the impact of production on the environment, improving the technological level and operating efficiency of the refinery. By investing in innovative environmental solutions, introducing modern digital production management technologies, we are setting new standards for industrial and environmental safety, which will determine the further development of the entire Russian oil refining industry.”
Recall that the construction of Biosfera began in October 2015. This is an environmental project of a comprehensive program for the modernization of oil refining assets of Gazprom Neft.
The construction of the "Biosphere" by order of the Government of the Russian Federation is included in the federal action plan for the Year of Ecology in Russia.
Investments - more than 9 billion rubles.
According to the associate professor of the Department of Biotechnology of the Russian University of Chemical Technology named after D.I. Mendeleev, Ph.D. Kuznetsova A.E., despite the high cost compared to other options, the MBR treatment technology is promising primarily for the treatment of domestic and industrial wastewater, especially in urban areas, since it can significantly increase the productivity of treatment facilities, increase their compactness and reduce occupied areas.
He also noted that in the world, due to the emergence of a new generation of membranes and an increase in the cost of urban land, there is a rapid growth in treatment plants with MBR - annually by 10-30%.
The complex includes a 2-stage flotation unit, a carbon filter, a membrane bioreactor, as well as reverse osmosis and dehydration systems.
In March 2016, the installation of RVS-1000 steel tanks for preliminary wastewater treatment began.
In June 2016, the Moscow Refinery began installation of RVS-10000 tanks to collect industrial wastewater and balance it in composition before being fed into the treatment system.
In August 2016, the installation of a carbon filter unit began to remove organic compounds and oil products from industrial effluents.
In December 2016, the installation of the flotation system equipment was completed (according to the pressure flotation technology, in which contaminants are removed from the water using air flow). In total, 6 devices were installed with a total capacity of more than 5 thousand m3/hour.
Specialist of the Department of Industrial Water Treatment Projects "NPK Mediana-Filter" M. Zavyalova spoke about the uniqueness of the project: “BOS “Biosfera” is designed to treat the production effluent of the Moscow Oil Refinery, and is a whole complex of new generation facilities. All effluents sequentially pass through flotation units, biological treatment units, membrane and carbon filters, and a reverse osmosis unit. All equipment is designed to maintain a stable mode of operation in different operating modes.
The membrane bioreactor planned in this unit will provide efficient biological wastewater treatment, and the unit for deep post-treatment of wastewater based on reverse osmosis units will provide highly purified water for reuse by the enterprise. After the launch of the complex, the volume of waste water will be significantly reduced and, as now, it will flow directly to the treatment facilities of Mosvodokanal. BOS “Biosfera” are unique treatment facilities and have no analogues in Russia.”
Throughout the entire period of construction of the complex at the Moscow Oil Refinery, indicators of water use efficiency have been steadily increasing. Now Biosfera will start operating at full capacity, and further modernization of the Moscow Oil Refinery will continue as planned until 2020.
Ahead of the launch of the most modern combined oil refining unit Euro +
Environmentalists from the public organization "Green Patrol" visited the Moscow Oil Refinery and took samples of wastewater, which were sent for analysis to an independent state chemical laboratory. Already in the fall, the refinery will start operating new treatment facilities "Biosfera": a modern biological complex will expand the composition of the plant's water treatment plants and will destroy almost all pollutants. After the launch of the "Biosphere", environmentalists will again come to the refinery, make a new sampling and analysis of wastewater - in order to compare them with the first sample. This will make it possible to verify the effectiveness of the new treatment complex and the environmental technologies used at the plant.
The construction of the Biosfera treatment facilities complex is one of the stages of the enterprise’s modernization and an important part of the environmental protection program that the owner of the plant, Gazprom Neft, has been implementing since 2011. The territory of the plant, where the Biosphere is now being built, was previously considered environmentally unfavorable. But in recent years, the situation has changed radically: according to Andrey Nagibin, chairman of the board of the all-Russian public organization Green Patrol, the Moscow Oil Refinery may well qualify for a Green Certificate.
This decision will be made after studying the information and monitoring the operation of the installation. But the openness of the enterprise and the demonstrated technologies have already been appreciated by us today, - Andrey Nagibin said. - The Moscow Oil Refinery has been under our close attention for several years. In the 90s, it was a real environmental threat to the city. Of particular concern was air pollution and groundwater pollution accumulated over 70 years on the territory of the enterprise, in the so-called "Black Sea", oil sludge. Today, on the site of this foul-smelling sludge reservoir, we see modern biological treatment facilities built. Already now there are no sharp unpleasant odors on the territory of the enterprise. There are no runoffs into the river, all open evaporation surfaces have been eliminated, water is purified with an efficiency of 95%, and after the launch of the Biosphere, there will be an almost closed cycle of water consumption.
Biosphere will use a unique technology for domestic oil refining for multi-stage wastewater treatment. First, wastewater will be driven through reliable mechanical treatment facilities that are already in operation. Then - through the "Biosphere": water will pass through the blocks of flotation, biological treatment, membrane and carbon filters, reverse osmosis unit.
Biosphere treatment facilities use special bacteria that can absorb and process oil residues, says Yuri Erokhin, head of the industrial safety and ecology department of the Moscow Oil Refinery. - In the final, purified water will pass through several hundred tons of activated carbon, as well as membranes, the pores of which are the size of a water molecule.
The plant's experts have calculated that after putting the "Biosphere" into operation, the enterprise will reduce water consumption by two and a half times. Almost 75% of the purified water will be reused in production - thus creating a practically closed cycle of its consumption.
Fundamental changes at the Moscow Oil Refinery in the field of ecology began back in 2011 with the advent of a new owner, Gazprom Neft, - says Roman Pukalov, director of environmental programs at the Green Patrol organization. - Over the years, emissions of pollutants into the atmospheric air have been significantly reduced, a system of integrated control over their concentrations has been introduced, a huge buffer pond, the so-called "Black Sea", has been completely eliminated, and a complex of closed mechanical treatment facilities has been built. The company does not dump its wastewater into the Moscow River, but cleans it on its own and then directly transfers it to the city's wastewater treatment facilities. After the launch of the Biosphere, the load on the city's wastewater treatment facilities should be significantly reduced.
By the way, the launch of the Biosphere treatment facilities is included in the federal program of events for the Year of Ecology in Russia.
Real, tangible benefits for the country's ecology are already being brought by practical measures, such as the launch of the Biosphere at the Moscow Oil Refinery, - says Andrey Nagibin, chairman of the board of the all-Russian public organization Green Patrol. - It is gratifying to note that the process of environmental modernization has been going on at the Moscow Oil Refinery for several years, regardless of the Year of Ecology, and will continue in the future.

250 billion rubles have been invested in the modernization of the Moscow Oil Refinery of the Gazprom Neft companies. Since 2011, thanks to the reconstruction of wastewater treatment plants, the company has reduced the environmental impact of production by 50%, and reduced emissions by 36%. It is planned that after the implementation of the next stage of environmental protection measures, by 2020 the impact of the plant on the environment will be reduced to almost zero.
The Moscow Oil Refinery, Moscow Oil Refinery, continues to build Biosfera, an innovative biological facility that will enable the refinery to achieve world-class water treatment performance and reuse up to 75 percent of industrial and storm water, a 360 correspondent said.
To evaluate the technologies of the future installation, the construction of which is an important part of the federal program of the Year of Ecology in Russia, the Green Patrol public environmental organization visited the plant. Its employees took control samples of treated wastewater in order to check the effectiveness of its work after the launch of the Biosphere.
"Biosphere" is a modern complex of treatment facilities that guarantee the almost complete removal of all pollutants from industrial effluents. Ecologists came to check how effective the future complex will be.
Ecologists say that ten years ago the plant could only dream of building such treatment facilities. Sewage accumulated in cesspools and their stench poisoned the life of the entire district. Everything changed in 2011 with the advent of a new shareholder - Gazprom Neft. A large-scale modernization began at the Moscow Oil Refinery, as a result of which, at first, a modern closed-type plant was built on the site of outdated treatment plants. The enterprise does not have any direct flows into the river, and all water from industrial complexes and storm sewers is purified at the plant, and only then goes through pipes to the city's wastewater treatment facilities. But the plant plans to increase the efficiency of water treatment and soon Biosfera will be added to modern closed mechanical treatment plants. In it, bacteria specially bred for this purpose will purify the water.
We simultaneously use membrane bioreactor technology, which allows us to simultaneously make these facilities modern and compact, and reverse osmosis technology, which allows us to return up to 75 percent of water to production, which means that the plant’s water consumption will be reduced by actually two-thirds.
- Yuri Erokhin, head of the industrial safety and ecology department of the Moscow Oil Refinery.
The plant will be able to reduce the consumption of river water by two and a half times, and the efficiency of water treatment after the launch of the Biosphere will increase to 99 percent.
The scale announced by the refinery is simply impressive. When the complex enters the operation stage, we will check again and show the population what water was and what it has become. Still, the effect will be quite serious.
- Andrey Nagibin, Chairman of the Board of the public organization "Green Patrol".
The Biosphere complex will begin its work in autumn. After that, the ecologists of the Green Patrol will once again descend on the plant to once again take water samples for analysis.

Reference
"Biosfera" is a multi-stage wastewater treatment system, where industrial effluents enter after preliminary treatment at the operating mechanical treatment facilities of the Moscow Oil Refinery. At the first stage, water passes through the pressure flotation unit, where all the remaining mechanical impurities and oil products are knocked out with a powerful air flow. After the flotators, the water passes to the central part of the plant - the membrane bioreactor.
Here, wastewater is mixed with sludge, which contains microorganisms that can absorb and process oil residues. They are adapted to this environment and were grown especially for Biosfera at the Lyubertsy treatment facilities of Mosvodokanal. After the sludge has fulfilled its function, it is filtered through thousands of membranes, the pore diameter of which is smaller than a human hair. This is the most advanced water treatment solution in existence. In addition, the tank is completely waterproofed, all exhaust gases are specially treated at photoionization stations, which guarantee the complete removal of odors and pollutants. The air is first cleaned on filters, and then disinfected with ultraviolet light.
In the final stage, purified water is successively passed under pressure through 200 tons of activated carbon, and then through 1440 reverse osmosis membranes, the cell size of which is not larger than a water molecule. Only after that, purified water is returned to production, and filtered oil products are recycled. Part of the purified water is transferred through pipes directly to the city's wastewater treatment plant. The enterprise has no open drains to the Moscow River. Even rainwater is collected in the storm sewer system and treated.
