Introduction. Water supply organizations are currently in need of innovative solutions and technologies based on the concept of the closed-loop resource cycle. The need for sustainable use of resources serves as the basis for changing the existing approach where worn-out resources are considered wastes. Materials and methods. In this paper, we show that it is expedient to restore the sorption properties of granulated activated carbon (GAC) by its reactivation and reuse in closed-loop recycling. We also present methods to study GAC properties and technology of reactivation. Results and discussion. Based on the results of the GAC samples’ analysis, it was found that, during reactivation, the mass content of each fraction changes with a strongly pronounced decrease in the content of large granules with a size of 1.18–2.00 mm and an increase in the content of small granules with a size of 0.60–1.00 mm. Besides, the apparent density of the sorption material changes and the volume of carbon that underwent two reactivations falls below 75%. Conclusion. GAC reactivation in dual-media rapid filters allows us to optimize not only the operating and financial expenses of the company but also those natural resources that would have been spent for the production of new carbon.

Introduction. The article provides data on engineering solutions for water treatment modules being part of the utility
and drinking water supply complexes in small settlements located in the Far North, where low-turbidity, high-colored
waters serve as the surface sources of water supply. These sources include the river networks of the Ob River (including
the southern area of the Gulf of Ob, Kara Sea), Pur River, and Taz River (including the Gulf of Taz, Kara Sea). Methods.
We present an analysis of the applied water treatment technologies, reagents, and materials, as well as water processing
modes, and establish the reasons for the unsatisfactory performance of the operated water treatment modules implementing
physical-and-chemical methods of water purification. Results. It is found that the use of granular materials as media for rapid filters (AS, MS, MZhF autocatalytic sorbents) is not very effective since they are intended for the purification of
colorless groundwater with a high content of dissociated compounds of divalent iron and manganese. Throughout the year, the modules operate without account for seasonal fluctuations in the qualitative composition of the source water and with reagents that have lost their active properties. Conclusion. Based on the conducted studies, we propose engineering solutions for the purification of low-turbidity, high-colored waters of surface sources, making it possible to achieve target quality indicators complying with the best available technologies.

Yermekov M. T., Rozhkova O. V., Sandibekova S. G., Tolysbayev Ye. T.CHALLENGES OF SNOW DISPOSAL AND INNOVATIVE SOLUTIONS IN THE CONDITIONS OF NUR-SULTAN
Introduction. In this paper, we analyze various methods of snow removal in urban areas and consider the most cost-effective
and efficient solutions for snow removal and disposal using heat from sewage drains by means of stationary snow-melting
points (SMP) in Nur-Sultan. In cooperation with Astana su Arnasy specialists, responsible for the operation of the city sewer
system, as well as cleaning and disinfection of urban sewage drains, we reviewed the main advantages and disadvantages.
Methods. The paper looks into the possibility of utilizing heat from sewage drains with the help of heat pumps. This method
has been successfully tested at a sewage treatment plant and is currently used to heat auxiliary premises. The same principle
can be applied in SMPs with a separate discharge of meltwater to the storm sewer. Results. Having studied the experience
of using various methods for snow removal in urban areas, we find that snow removal with the use of sewage drains through
the creation of special snow-melting complexes integrated with the city sewer system is the most promising method for
Nur-Sultan since it allows for reducing costs, intensifying the process of snow melting, and eliminating the hazardous
impact of meltwater on the environment. Conclusion. To ensure successful implementation and use of this snow removal
method in Nur-Sultan, it is required to conduct a number of additional studies on the impact of sewage treatment plants on
the technological processes, as well as to test options for separating sewage drains with the help of heat pumps, and, based
on the studies conducted, to determine the final configuration of snow-melting complexes.

Reshetnyak O. S., Komarov R. S.TRENDS IN THE VARIABILITY OF THE CHEMICAL COMPOSITION AND WATER POLLUTION LEVEL IN THE KUBAN RIVER
Introduction. The paper explores the long-term spatial and temporal variability of the chemical composition and water quality
in the Kuban River. Methods. To study the variability of the chemical composition of river water, we analyzed data from
systematic observations over the concentrations of major ions, biogenic and organic substances, petroleum products and
heavy metals from 2010 to 2017. To describe the variability of water quality, we used such indicators as water quality class,
water pollution level, and characteristic pollutants. Results. It is shown that the spatial change in the chemical composition is
uneven — a number of components in the water have low concentrations in the upper reaches, increasing in the lower part of
the river. Others are characterized by high concentrations in the middle reaches, followed by a decrease towards the mouth.
Over time, the change in the concentrations of chlorides, sulfates, organic substances and petroleum products increases. As for
the content of nitrates, a slight decrease was detected in its variability. For the remaining chemicals, there were no clear trends.
We established that in most cases the water in the Kuban River can be classified as polluted and very polluted (water quality
class 3). We also found that the nature of river water pollution regarding a number of components is stable. Conclusion. In
modern conditions of sharp climate changes and anthropogenic impact, the identified features of the chemical composition and
trends in water quality variability of the Kuban River are of great practical importance and can be used in the development
of environmentally sound recommendations for improving water quality and the state of water ecosystems in the river basin.

Introduction. Manzherok Lake is the only habitat of the Red Book endemic water chestnut (Trapa pectinata) in the Altai
Republic. In the second half of the 20th century, its catchment area underwent significant anthropogenic transformations,
increasing the degradation of the lake ecosystem. To stabilize the state of the reservoir, in 2017–2018, its central part was
cleared of the bottom silt (sapropels). Methods. In 2019–2020, as part of monitoring the state of the lake’s water area, 11
rounds of water testing were conducted at six points on two profiles. In total, we collected 72 water samples and studied their
chemical composition and, partially, microbiological parameters. The suspended matter content, turbidity and oxidability
of water were determined on an ongoing basis. Results. We identified a trend for a consistent decrease in the content of
suspended particles and other indicators of the ecological state of water. The forecast for 2020 to improve the quality of lake
water was confirmed. We also revealed other positive changes in the ecological state of Manzherok Lake after its clearing.
Conclusion. We determined features of lake ecosystem self-restoration after rehabilitation and made a forecast regarding
the preservation of positive trends in the restoration of water quality for the next 1–2 years. It is shown that the lake clearing
of the bottom silt did not solve the problem of its rehabilitation to the full.

Introduction. This paper is the first to address the state of phytoplankton in eutrophic Svyatozero Lake (61о32´ N, 33о35´ E.),
used for trout farming in the Republic of Karelia, in the North-Western Region of Russia, during the period of water bloom.
For northern reservoirs, water bloom is not a typical phenomenon. However, due to climate warming and the large-scale
development of trout breeding in the region, it becomes more urgent to study blooming reservoirs and related consequences
for northern aquatic ecosystems and humans. Methods. We processed phytoplankton samples and measured photosynthesis
using conventional methods. The concentration of chlorophyll a in water was determined spectrophotometrically, and the
content of cyanotoxins was estimated by liquid chromatography-mass spectrometry. Results. In September 2019, we studied
the structural, quantitative and functional characteristics of phytoplankton in the bloom spot. The phytoplankton abundance
was 198.712 mln cells/l, the biomass was 14.945 mg/l, and the concentration of chlorophyll а reached 215.3 μg/l, which
corresponded to the β-eutrophic state of the ecosystem in the study area. It was revealed that cyanobacteria corresponded to
99.8% of the biomass and 96.7% of the abundance. The species of the genus Microcystis were dominant (42%). They are
well-known potential producers of cyanobacterial hepatotoxins, in particular, microcystins. We established the presence of
microcystins. Their intracellular and extracellular concentrations were equal and in total amounted to 12.56 μg/l. We also
identified eight structural variants of microcystins; among those, [D-Asp3] MC-RR accounted for up to 90% of the total content.
The most toxic MC-LR variant was present in trace amounts only in biomass. According to the WHO standards, the content
of microcystins and the number of cyanobacterial cells in the Svyatozero Lake bloom spot corresponds to average danger in
the case of recreational use and can pose a threat to human health. Conclusion. It is necessary to monitor the phytoplankton
composition, the presence of potentially toxic cyanobacterial species and cyanotoxins, as well as the state of trout farmed in the
waters of Svyatozero Lake, since cyanotoxins can accumulate in fish tissues.

Shabalin V. V., Rogozhina T. S.DETERMINATION OF COMPONENTS, DISSOLVED ORGANIC AND INORGANIC SUBSTANCES IN NATURAL WATERS
Introduction. Large urban agglomerations have to deal with issues related to the high-quality drinking water supply. These
issues are mainly due to water quality deterioration, poor condition and severe wear of water supply infrastructure facilities.
Materials and methods. In our study, we analyze the composition of drinking water in the water supply system of St. Petersburg
for SiO2 and Al2O3 nanoparticles and organic substances, including soluble proteins, protein components, and salts. For this
purpose, we estimated the concentration and distribution of nanoparticles and organic impurities in the sediment formed
after water evaporation from a sample in the form of a droplet. During the process, the following methods were used: the
method for dehydration of water droplets with the formation of a solid phase, the methods for optical analysis of the sediment
structure based on image analysis and recognition (photo and video recording of microscopic images), mathematical modeling
of sediment structures’ formation, and statistical analysis of the results. Results. The presence of impurities in water was
determined by the formation of periodic annular ring structures in sediments of aqueous solutions. The analysis of the structures
obtained made it possible to determine the composition of the mixture and percentage content of individual fractions by the
type of structural elements and their periodicity. We also developed a mathematical model simulating the processes of particle
settling out of a solution. The calculations were carried out using model liquids and made it possible to obtain dependencies for
the distribution of various dissolved particles in the structure of the solid phase, as well as to describe the staged mechanism in
settling during its formation.

Krasavtseva E. A., Sandimirov S. S.STATE OF WATER BODIES IN THE AREA OF INFLUENCE OF MINING AND PROCESSING ENTERPRISES (CASE STUDY OF LOVOZERSKY MINING AND PROCESSING PLANT)
Introduction. This extended study is the first to analyze the chemical composition of the surface waters and bottom sediments of the lakes affected to various extents by Lovozersky Mining and Processing Plant (Revda urban settlement, Murmansk Region) performing mining and processing of rare metal ores. Methods. During the study, we used data obtained in the course of research in 1995–2005 and 2019–2020. Water and bottom sediment samples were analyzed using various methods. The total contents of elements in the bottom sediments were compared with the background values or, in their absence, with the clarke contents of elements in the Earth’s crust. To assess the level of pollution in the Sergevan River receiving wastewater from the plant, the maximum pollution index was calculated. Results. Over the past 35 years, the chemical composition of the surface waters of nearby water bodies underwent minor changes. No significant excess of maximum permissible concentrations for fishery water bodies was found. The comparison of the contents of heavy metals in the bottom sediments collected from Lakes Ilma and Krivoye with the background values revealed contamination of the Lake Ilma with strontium, zinc and manganese. Besides, a multiple excess of the content of rare earth elements (La, Ce, Pr, Nd), Nb and Ta was established in the bottom sediments of Lake Ilma in comparison with that in Lake Krivoye. The analysis of the river water samples taken at different distances upstream and downstream the site of wastewater discharge confirmed the assumption about the pollution of the Sergevan River by wastewater from the plant. Conclusion. The pollution of the water bodies is mainly caused by wastewater discharged from the plant, however, the increased content of rare earth elements in the bottom sediments of Lake Ilma may be due to air transport of particles of loparite ore concentration tailings, drainage from tailing dams, or degradation of underlying rocks.

Telyatnikova A. M., Fedorov S. V., Kudryavtsev A. V.MODELING THE OPERATION OF SEPARATION CHAMBERS
Introduction. Separation chambers are designed and built for separate and partially separate sewerage systems. Their main
function is to separate the flow of relatively clean water during heavy rain. This allows the discharge of such water without
treatment into water bodies or storage tanks. The approach reduces the load of wastewater treatment plants. To design
separation chambers, we need to understand how their design features affect the process of flow separation. It is possible to
study the hydraulic characteristics of separation chambers of any design with the help of computer simulation. Two designs
of separation chambers were investigated: a circular spillway with a full-scale prototype and a spiral spillway proposed
by the authors. Methods. The research was based on simulation in the ANSYS CFX finite element analysis software. For
each design, a series of five experiments with different incoming flow rates was performed. Results. Models of two types
of separation chambers were developed and qualitatively evaluated. The hydraulic characteristics were established and
quantified: the uniformity of the flow discharged for treatment and the spillway discharge coefficient. Conclusion. As a
result, a principled approach was formed and tested. Using this approach, it is possible to study the hydraulic characteristics
of separation chambers of various designs for their further use in the sewerage system.

Introduction. The paper addresses the importance of extracting the labile form of phosphorus from wastewater with
the possibility of its further use. The advantages of sorption methods and the prospects of using amorphous silica as an
ameliorant with a prolonged fertilizing effect are considered. Methods. We performed experimental modeling of phosphates
extraction from model solutions and a sludge mixture from regional sewage treatment plants. Amorphous silica obtained
from local nepheline raw materials in acid treatment using a patented technology was used as sorbents. Results. A sorbent
based on amorphous silica with a pore diameter of 8.41 nm was obtained. Its sorption capacity exceeds 29 mgP/g in the
phosphate form, which corresponds to the average level of phosphorus removal, noted for a number of sorbents used in
the international practice of wastewater dephosphorization when producing unconventional ameliorants. Conclusion. For
effective phosphorus removal from municipal wastewater to obtain an unconventional ameliorant with a fertilizing effect in
terms of Si and P, sorbent consumption of 1 g/l is sufficient.

Volkova N. E., Podovalova S. V., Umerova L. R.METHODOLOGICAL APPROACHES FOR ASSESSING THE IMPACT OF NATURAL AND ANTHROPOGENIC FACTORS ON RIVER GEOSYSTEMS
Introduction. The increasing shortage of water resources in the Republic of Crimea, due to water supplies from the external
water source being shut off, emphasized the need to rationally use the existing water resource potential, which in turn
requires a balance between the water users’ interests and maintaining a favorable environmental situation in the peninsula’s
watercourses. Although in Russian and global practice there is a whole range of approaches to assessing the impact of
natural and anthropogenic factors on the state of river geosystems, not all of them are applicable to solving the indicated
problem. Methods: By testing integrated techniques, methods and models for assessing the impact of human activity on the
stability of river natural and engineering systems (using the Zuya River as an example), we selected the most appropriate
approach to develop viable solutions in water management. Results: By comparing the possibilities of using the scoring
index method to assess the stability and vulnerability of watercourses to changes in physical and geographical as well as
hydrological parameters and water quality, and methodology for the integrated assessment of the geoecological state of
water resources of small rivers and the system model “Minor River Basin”, we revealed that only with the use of the latter
it is possible not only to assess the real situation but also identify the reasons that impede the rational use of the peninsula’s
watercourses. Conclusion: When developing decisions related to water management in the Republic of Crimea, the use of
a suitable methodological approach to assessing the impact of natural and anthropogenic factors on the stability of river
geosystems will make it possible to avoid mistakes when choosing measures and prioritizing actions aimed at the rational
use of the existing water resource potential.

Introduction. This article addresses the long-term dynamics of Oka River basin pollution. The basin serves as the main
source of drinking water and a receiver of wastewater from a number of regions in European Russia. Methods. We assessed
the water quality by 12 main hydrochemical indicators and constructed maps of their distribution with a breakdown into
two periods (1990–1999 and 2000–2017). The anthropogenic load along the section in the city of Gorbatov was determined.
Spearman’s rank correlation coefficients and their statistical significance were calculated. Results. For 18 gauging stations
with 25 and more years of observations, the magnitude of the linear trend (%/year) was estimated using the Theil–Sen
estimator, and the statistical significance of the linear trend (Mann–Kendall test) was assessed for individual stations and
the entire basin, using a modified Walker test. The runoff of pollutants from the urban territory was estimated between the
sections upstream and downstream the cities in the upper reaches of the Oka River basin. The volumes of pollutants in the
Oka River from the cities of Orel, Belev and Kaluga were determined for the period of 1990–2017. The calculations of the
pollutant runoff, performed between the sections upstream and downstream the cities, made it possible to determine the
role of the cities in the formation of point pollution in the upper reaches of the Oka River. The anthropogenic load along
the length of the river in terms of the influx of chemicals varies from “low” to “high”. The load is largely due to the intake
of pollutants since water bodies and watercourses serve as receivers of both treated and insufficiently treated wastewater
from various enterprises. Conclusion. Almost throughout the basin, the water quality is under stress. The statistical analysis
showed the existing relationship between a certain type of land use and the concentration of substances in surface waters.
It was revealed that the self-cleaning capacity of the river is sufficient to prevent pollutants from accumulating along it.
Key words: Oka River, river flow, water quality, anthropogenic load, influx of chemicals.

Klimovskiy N. V., Moreva O. Y., Matveev N. Y., Novoselov A. P.ECOLOGICAL STATE OF THE ZIMNYAYA ZOLOTITSA RIVER IN THE AREA OF THE INDIRECT IMPACT OF THE MINING AND PROCESSING PLANT
Introduction. Medium rivers play an important role in the environment: draining the large catchment area, they determine
the water content and quality as well as hydrological conditions in large watercourses. The joint effect of such factors as
the small size of these rivers and human activity disturbs the balance of ecosystems, thus increasing the vulnerability of the
rivers. Significant negative changes tend to occur faster and stronger in river valleys. Our aim was to study the ecological
state of the Zimnyaya Zolotitsa River ecosystem in the area of the indirect impact of wastewater from the mining and
processing plant in the Lomonosov diamond field. Methods. In the course of the study, we used the standard methods for
determining the main biogenic elements and oil hydrocarbons. Results. The paper provides data on the content of biogenic
elements in water, pH value, dissolved oxygen and mineralization, as well as the content of oil hydrocarbons in water
and bottom sediments. Conclusion. As a result of the studies, it was found that in the summer observation period, the
concentrations of phosphorus, nitrogen and silicon salts as well as oil hydrocarbons did not exceed the maximum allowable
values for fishery reservoirs.
Key words: Zimnyaya Zolotitsa River, dissolved oxygen, pH value, biogenic elements, oil hydrocarbons, bottom sediments.
