The Wastewater Disposal System Modernization during Processing of Amber Deposit as a Way to Reduce the Anthropogenic Load on the Baltic Sea Ecosystem

Strizhenok Alexey V., Korelskiy Denis S., Kuznetsov Vladimir S.

Journal of Ecological Engineering

2019

Vol. 20, nr 3

30--35

The research is devoted to assessing the negative impact of the amber-succinite deposit in the Kaliningrad region as one of the sources of complex pollution of the Baltic Sea waters. The Baltic Sea is one of the most polluted water bodies in Europe today. There are many natural and anthropogenic factors that cause this ecological situation. Industry is one of the significant contributors to the pollution of the waters of the Baltic Sea. The industrial wastewater discharged into the Baltic Sea often does not comply with the state ecological standards. The wastewater disposal system modernization by creating a recycled water supply is one of the most effective ways to reduce the negative impact of industrial wastewater on the Baltic Sea ecosystem nowadays. This technological solution allows to significantly reduce or to completely prevent the discharge of wastewater into the Baltic Sea.

Development of an Engineer Operation Aimed at the Reduction of Atmospheric Dust Pollution in the Decommissioning of Iron-Ore Treatment Waste

Suprun Igor, Kuznetsov Vladimir S., Ivanov Andrey V.

Journal of Ecological Engineering

2019

Vol. 20, nr 4

23--28

This work covers the pollution of the atmosphere during the work of the Mikhailovsky Mining and Refining Facility which is located within 100 km from the city of Kursk, in the city of Zheleznogorsk. Over the past few years in the whole world, the anthropogenic activity, connected mainly with the locations of mineral production and those of mineral treatment and processing, has become increasingly dangerous for the natural environment. Resource development in open pits causes the formation of inorganic dust. The dust is released into the atmosphere at all stages of the enterprise’s technical process. The principal sources generating inorganic dust during open mining of iron deposits include: blasting operations in an open pit, the work of transfer points, the enrichment process at a factory, pellet firing as well as dusting from the surfaces of stock dumps and dry tailings beaches.
