“…Thus, the research results show that the implementation of the proposed measures makes it possible to achieve the required quality of the purified wastewater that will meet the requirements for the use of water for technical purposes of the circulating water supply cycle of the plant and ensure uninterrupted operation of the heat exchange equipment (Galkina, O., Blahodarna, H., 2019). Such purified waste water can be used for the technical purposes of the plant.…”

The paper proposes technical solutions for the use of the reagent method of water preparation at coke plants in order to bring it to a quality suitable for use in the circulating water supply system of the PJSC Kharkiv Coke Plan. It is proposed to dilute phenolic water in a biochemical installation in a mixer before purification and to purify water with a flocculant. The paper recommends dosing the flocculant solution automatically using a preparation station. Additional purification of the clarified water is carried out using a filtration unit with a filter media from a layer of quartz sand. The economic effect from the implementation of the technical measures is achieved not only due to the reduction in fresh water consumption by 60 540 m3/year and the cessation of the discharge of phenolic water into the city sewer network, but also the replacement of the reagent with a more efficient one and a decrease in its consumption. It has been found that the introduction of the technical solutions for the circulating water supply system is economically and environmentally justifiable.

“…Потім вона дозується в систему водопостачання заводу. Важливо відзначити, що використання мікрофільтрів та ультрафіолетового опромінювання також призводить до значного зменшення кількості завислих речовин у системі водопостачання, доводячи їх до нормативних рівнів, і забезпечує безперебійну роботу теплообмінників [18].…”

This academic paper explores various assessment methods used to evaluate the environmental impact of industrial enterprises, specifically focusing on coke plants. The study emphasises the widespread use of a global risk-based approach for assessing the environmental risks posed by such enterprises to both the environment and public health. This approach involves predicting potential future environmental consequences under different scenarios, with the choice of a specific method dependent on the particular conditions, objectives, and available resources.The analysis of these assessment methods reveals the prevalence of an integrated approach, which comprehensively evaluates multiple aspects of an industrial enterprise’s environmental impact. Moreover, the research underscores the importance of adopting modern technologies and strategies to enhance water supply and wastewater management efficiency for environmental preservation.The assessment of the ‘Kharkiv Coke Plant’ indicates minimal impact on land inundation issues, with little effect on groundwater quality. However, the excessive consumption of freshwater remains a significant concern, necessitating improved efficiency in the operation of the plant’s wastewater recycling systems. To evaluate the enterprise’s influence on surface waters, notably the Lopan and Udy rivers, the paper calculates the volume and flow of wastewater originating from the facility’s premises.Additionally, environmental impact assessment is conducted using key environmental indicators, including the alarm index, hazard index, and priority index. In light of the identified environmental challenges at the investigated industrial facility, including wastewater discharge into the municipal sewerage system, high water consumption, and phenol emissions from the quenching tower, the paper proposes a solution. This solution entails enhancing the plant’s water recycling infrastructure through the implementation of a closed-loop water recycling system and improving the efficiency of the biochemical plant. This approach aims to mitigate the environmental impact of the enterprise while promoting sustainable water management practices. Keywords: environmental problems, water resources, degree of pollution, enterprises.
