The Path to Balance

The film tells about the processes of industrial water purification at various chemical enterprises. 1 part. Panorama of the Shchekinskiy Production Association "Azot" in the Tula Region. General view of production buildings. Views of the park in the State Memorial and Natural Reserve "Museum-Estate of Leo Tolstoy" Yasnaya Polyana ", a pond. Landscapes surrounding Yasnaya Polyana. House-Museum of Leo Tolstoy. A group of excursionists at the House-Museum. The guide conducts an excursion. General view of the path in the park. A road sign by the road leading to Yasnaya Polyana. Bus stop by the highway. The movement of road transport on the highway. Entrance to the territory of the memorial and natural reserve "Museum-estate of Leo Tolstoy" Yasnaya Polyana ". A policeman stands at the entrance, observes the order. Tourists are passing by. General view of the sentry post-laboratory of the Shchekinskiy PO "Azot". Laboratory workers are monitoring the composition of the air in the vicinity of Yasnaya Polyana. Internal view of the post-laboratory. Employees of one of the workshops of the Azot enterprise monitor the work of the automated production system, which makes it possible to reduce incl. hazardous industrial waste. Production processes in the shops of PA "Azot": Neutralization of liquid nitrogen oxides using a special technology: general view of special mixers, where liquid nitrogen oxides are neutralized with a soda solution, then fed to nitrification in the form of effluents. General view of liquid nitrogen oxides effluents, which are easily mixed with easily oxidized waste waters of organic production. Thus, an anerobic environment suitable for microbial nutrition is created. A panorama of the factory buildings of the North Donetsk Production Association "Azot", where the technology of water reuse is used and a closed water circulation system has been created - its own looped river. Landscapes of the Seversky Donets River. Men in a boat catching fish with nets. The man takes out the caught carp from the nets. Part 2. General view of the factory buildings of the North Donetsk Production Association "Azot". Production processes in the workshops of the enterprise. The cleaning production at the enterprise is based on a combination of local and group cleaning methods. General view of the treatment facilities of the biological complex. General view of the wastewater pretreatment process. The water runs along the gutters, then undergoes mechanical treatment, i.e. various suspensions are removed from it. Water supply to aeration tanks (treatment facilities), where chemical purity is returned to it. An employee of one of the company's laboratories takes water for its subsequent analysis for the composition of various substances in it. A woman looks through a microscope. Activated sludge from aeration tanks (treatment facilities) under a microscope. Female lab workers at work in the laboratory. View of flasks with water before and after cleaning. General view of the Kharkov River (filmed from the sail). Boats at the shore. A group of scientists and designers at the model of the future Pervomaisky Chemical Plant. General view of the built Pervomaisky chemical plant near Kharkov. At the enterprise, for the first time in the world practice, it was possible to avoid pollution of water bodies by sewage. Instead of the usual general flow, closed cycles were used for each production. This allowed the waste water to be purified and then recycled again. Water cooling was changed to air cooling: so-called cooling evaporators were used. Deer in open-air cages at the enterprise's zoo. Black swans, ducks swim in the reservoir. General view of flowering mallow in the territory of the plant. View of the shop before the chemical post-treatment of waste water. Production processes in the workshop. The type of absorbers is special tanks where organic impurities are extracted from the effluent with the help of activated carbon. A type of regeneration furnace, where the impurities are burned out, and the coal restores its activity and returns to the process. Water supply to ion-exchange filters, where calcium, magnesium and ions of other metals are separated from it. Type of purified water returned to production. Production of complex fertilizers in one of the workshops of the enterprise. Fertilizer packaging in paper bags. Part 3. Tractors plow the land in the fields. A herd of cows is walking through the pasture. Landscape: fields, forest, country road. Blasting operations in a quarry. The excavator loads the rock. Production processes in the shops of one of the enterprises of the chemical industry. Wastewater flows into the river. A pleasure boat is sailing along the river. Smoke from the chimneys of enterprises and thermal power plants. Employees of one of the enterprises are monitoring the readings of instruments for the level of environmental pollution. Production of synthetic coatings in the workshop of a chemical industry enterprise. Factory workers are stacking sheets of nylon. View of the main dispatching console of the enterprise. Dispatcher at the control panel. Aircraft on the airfield. The IL-18 aircraft, on board of which the laboratory for atmospheric control is located, is preparing for flight. Pilots in the cockpit. The plane is taking off. General view of the mountain range (filmed from an airplane). Laboratory staff monitor instrument readings.
