Wastewater treatment facilities of Adler city

Summary

The wastewater treatment facilities in Adler (Greater Sochi Area), some of the most modern facilities in Russia were built as a part of the Olympic infrastructure. The Adler wastewater treatment facilities were designed on the basis of innovative solutions: for the first time 3-D engineering was applied; the best available techniques were taken into account; zero emission system was implemented – all the facilities are covered by airproof covers; the air from the facilities is supplied to the gas cleaning system; sludge handling includes dewatering and drying; consequently the amount of sludge is reduced and sludge is disinfected. The process scheme stipulated by the project includes primary mechanical treatment of wastewater, full biological treatment, tertiary treatment and effluent disinfection. The system of generated sludge utilization includes mechanical dewatering in centrifuges with subsequent additional drying. The design concept behind the project formulated more than 10 years ago (2008 project) determined the development path of the advanced treatment technologies and served as an example of the wastewater treatment facilities built according to the principle of the best avai­lable techniques.

Integrated upgrade of the Samara municipal wastewater treatment facilities

Summary

The experience of «Samarskie Kommunal’nye Sistemy» LLC in designing, constructing and upgrading the municipal wastewater treatment facilities with a capacity of 450–750 thousand m3/day is presented. Considering the adverse ecological state of the midstream and downstream of the Volga River the task of improving the efficiency of wastewater treatment is of top priority that has been approved by the Program adopted by the Department of Energy and Public Utilities of the Samara Area for 2013–2019. The results of retrofitting wastewater biological treatment technology on the basis of UCT Process with unique zone and recycling layout barrangement by modifying the existing capacities of four-corridor aeration tanks are presented. The justified technical solutions of the key facilities that determine the energy and structural efficiency of the project of upgrading the air blower house with the use of mechanically regulated air blowers (the capacity range of each 59.4–132.1 thousand Nm3/h) and constructing two sludge pumping stations with 15000–27360 m3/h regulated wastewater flow are set. The process automated control system has been introduced. The tied to time design works required fast and efficiency calculation methods with the use of process simulation modeling in GPS-X environment (ASM2d model), computerized fluid dynamics – in ANSYS Fluent environment. The prediction of the dynamics of the treatment efficiency changing within 24 hours while ensuring average daily concentrations in mg/l – suspended solids – 15.5; BOD5 – 5.7; COD – 34.9;
N–NH4 – 0.25; N–NO2, N–NO3 – 7.02; P–PO4 – 0.68 is given. Relatively high washout of suspended solids is caused by the significant design value of sludge index 150 сm3/g. In the implementation phase of the environmentally efficient measures the construction of tertiary treatment facilities valued at 400 million rubles (about 30% of the total cost of the upgrade of the entire facilities) was rendered economically unviable. Before commissioning the actual energy saving of 13 mln kW·h/year including 8.8 mln kW·h/year owing to the replaced air blowers, 4.2 mln kW·h/year owing to the sludge pumping stations with submerged pumps that replaced airlift was achieved. The performance targets of the projects and the technical solutions applied measure up to the best available technologies.

Simulation of Biochemical Processes of Wastewater Treatment as a Basis of WWTFs Retechnologization

Summary

In accordance with the requirements of environmental legislation it is necessary to introduce the best available technologies at biological WWTFs. In the course of development of plans of reconstruction and capital repair of sewerage treatment facilities it is necessary to carry out the variant examination of flow charts of treatment on the basis of imitation simulation. A detailed analysis and comparison of different models of processes with activated sludge have been conducted. Treatment processes at large number of facilities have been simulated with the help of the Ecosim 3P program developed by the Ecopolymer Company. It is shown that the imitation simulation makes it possible to ensure a high accuracy of treatment results prediction. An approach to the retechnologization of treatment facilities based on mathematical models of biochemical processes with activated sludge has been developed. This approach tested experimentally at a whole number of biological treatment stations has made it possible to carry out their retechnologization resulted in considerable reduction of biogenic elements in treated water.

New approaches to the regulation of effluent discharge to water bodies

Summary

The list of the regulatory legal acts – federal laws, RF government decrees and executive orders is presented as well as the decrees of the RF Ministry of Natural Resources and Environment enacted for the past years. The purpose of the enactment is the reform of the environmental legislation in the field of the governmental regulation of the impact the economic activity produces on water bodies; the regulation consists in transferring from the existing principles of regulating pollutants discharge based on the water quality standards for water bodies of commercial fishing importance to the regulation based on the best available techniques. Special attention is paid to Decree of the RF Government of September 13, 2016 No. 913 and Decree of the RF Ministry of Natural Resources and Environment of November 15, 2016 No. 598 on the introduction of amendments to «Methods of developing the standards of permissible discharges of substances and microorganisms into water bodies for water users» (2007). The informative technical guidebook ITS 10-2015 «Wastewater treatment in the public wastewater disposal systems of communities, municipal districts» is considered. The need in reviewing the provisions of section 9 of the technical guide «Recommendations for designing the systems of collection, removal and treatment of the runoff from residential areas, industrial sites; and determining the conditions for effluent discharge into the water bodies» (2015) developed by the experts of «NII VODGEO» JSC is substantiated.

Regulation of wastewater discharges within the framework
of the national environmental policy

Summary

The interrelation of the environmental legal relations in the field of regulating pollution discharges into the water bodies and public utilities operation is considered. Regulation of wastewater discharges and environmental payments for the negative impact on the water bodies are directly interconnected. Above-limit payment for discharges is one of the factors of the bankruptcy of water and wastewater utilities. Amendments to the system of regulating the negative impact on the water bodies introduced in 2015 could neither solve the existing problems nor eliminate the contradictions between the interests of the institutions of the RF Ministry of Natural Resources and Environmental Protection, water and wastewater utilities and national fiscal interests. According to the current methods of regulation drafting technically unachievable requirements to the effluent discharges are set to the water and wastewater utilities; and failure to observe them is subject to substantial financial responsibility. Shifting a part of the financial responsibility from water and wastewater utilities to business did not improve the economic performances of water and wastewater services but placed additional financial burden on business. No changes in discharge regulations that were envisaged in Federal Law No. 73-FZ of June 3rd, 2006 «On the enactment of the Water Code of the Russian Federation» occurred due to the lack of the regulatory and legal framework expected from the institutions of the RF Ministry of Natural Resources and Environmental Protection. The amendments to the environmental regulations introduced into the legal framework do not correlate with each other and reflect the interests of different institutions. It is evidence of the absence of the national environmental policy. The constituted statutory regulations must correspond to the provisions of the national environmental policy, solve the tasks set by the policy, eliminate the emerging contradictions. The basic principles that must make the foundation of the national environmental policy are presented. The main principles are the balance of the public interests, environmental interests, the interests of water and wastewater utilities and business, all-level budgets, technically achievable requirements to the negative impact and the priority of environmental protection over the national fiscal interests.

Determination of technological indicators of municipal wastewater treatment quality corresponding to the use of the best available techniques

Summary

In 2015 «Wastewater treatment in public wastewater disposal systems of communities, urban districts» information and technical gui­dance was compiled (ITG 10-2105). The document has been developed for the first time in Russia and has no parallels in European Union. One of the main problems in compiling ITG 10-2105 was developing the methodology of determining the technological indicators of the best available techniques. The analysis of this methodology was carried out in comparison with the existing in EC perspective approaches to the determination of the technological indicators including: projects selection and split up into groups; acquisition of data on the emissions into the atmosphere; selection of pollutants; analysis of the available information on discharges; differentiated determination of the emission level in relation to the best available techniques. The technological indicators of pollutants removed in the traditional biological treatment processes (suspended solids, BOD5, COD) were determined in the process of analyzing the data obtained by questioning the branch projects. Determination of the technological indicators for nitrogen and phosphorus compounds is based greatly on the expert assessment due to the small number of projects using BAT and due to the differences in the technologies applied. Generally the method for determining the technological indicators of BAT to the full extent corresponded to the practices currently used for this purpose in EC. In future during the preparation for ITG 10-2015 revision it is recommended to carry out monitoring and technological audit of BAT reference-projects as well as of the perspective technologies.

Specific features of the transition to the process regulation of public wastewater disposal systems

Summary

The results of the analysis of proposed laws and regulations in furtherance of the legislation on process regulation of public wastewater disposal systems are presented. Pros and cons of the new regulation system are considered. The necessity of revising the maximum permissible concentrations of pollutants in effluent discharged into a water body is substantiated. The problem of excessive environmental requirements to effluent discharges that had been in power for many years in the country did not lose relevance in 2019. Permissible concentrations of substances discharged into water bodies remained on average two times tighter than in European countries. The purpose of the work was to substantiate proposals for amending approved and developing regulatory legal acts. To achieve this goal domestic and European legislation related to the process regulation was analyzed and compared. The existing system of dividing water bodies into categories is unnecessarily complicated and has an obvious imbalance (up to 95%) towards fisheries and standards; therefore it is proposed to approve three categories of water bodies to establish standards for the discharge of effluents from public wastewater disposal systems: premium fisheries category, primary fisheries category, public household category with evaluation criteria according to the existing methodology.

Use of UV-disinfection in water supply and wastewater disposal systems of Novosibirsk

Summary

Vodokanal of the city of Novosibirsk has been one of the first water and wastewater utilities in large Russian cities to completely switch to the disinfection of drinking water and wastewater with ultraviolet irradiation. Advanced multi-barrier technologies for the preparation of drinking water (combined use of UV disinfection and chlorination) provided for obtaining safe drinking water of high quality. UV units introduced at the pumping-filtration stations (PFS-1 and PFS-5) of the city provide for the reliable disinfection of filtered purified water up to the requirements of SanPiN 2.1.4.1074-01-01, perform a barrier role against pathogenic microorganisms of bacterial, viral and parasitic nature. UV equipment installed at the municipal wastewater treatment facilities with a total capacity of 600 thousand m3/day ensures the required degree of disinfection in accordance with SanPiN 2.1.5.980-00 (radiation dose not less than 40 mJ/cm2). The UV-disinfection station built on the basis of tray-type vertical type equipment manufactured by «LIT» SPA is installed in three concrete flow channels. To improve the energy efficiency of the UV disinfection station operating under the conditions of uneven incoming wastewater flow during the day a system for the UV irradiation rate control by signals from an external flow meter and a tau meter measuring the UV transmittance was retrofitted. Ultraviolet disinfection of effluent does not affect the Ob River. Used for several years UV disinfection of wastewater and up to now is the best available technology.

Development of the Regional program  of protecting Moscow water bodies from pollution with surface runoff

Summary

The description of the Moscow system of surface runoff disposal and treatment characterized by the extensive use of the urban hyd­rographical system as elements of the drainage network is presented. Nowadays the system is positioned as «urban collector-river drainage system» that encompasses up to 90% of the Moscow territory within its old boundaries. It is noted that surface runoff from the developed areas, properly collected and diffused, is a main source of technogenic pollution and degradation of the water bodies in Moscow in the city area. Under current conditions improving their ecological state is possible only by the implementation of measures on reducing the anthropogenic impact on the water bodies and their catchment basins; eliminating the accumulated environmental damage; restoring the self-purification capacity and protecting underground water from pollution. To perform these tasks the Regional program of protecting the Moscow water bodies from surface runoff pollution basing on the principles of regulating the discharge of pollutants on the basis of the best available techniques of wastewater treatment is proposed. In the process of developing the Regional program together with the information-technical reference book ITS 10-2015 «Wastewater treatment with the use of public wastewater disposal systems of settlements, urban districts» a number of governmental bylaws developed and adopted in furtherance of the provisions of Federal  Laws No. 219-FZ and No. 416-FZ should be also taken into account.

State of the system of regulating discharges of pollutants and improvement of water body protection mechanisms

Summary

The analysis of the existing Russian system that regulates pollutant discharges (in particular, draft bill No. 584587-5) and charges, study of the similar international experience allowed making a conclusion on the necessity of cardinal changing the fundamentals of the legislation in this area. Most essential problems are as follows: «zero impact» principle; disregard of the criterion of technical achievability of the established requirements; the system of «permissible discharge rates (PDR) – limits»; reference nature of the legislation and practically total lack of the directly applicable standards; entirely individual requirements to the water users in the absence of general standards; complicated and labor intensive development of PDRs; multistage and expensive system of obtaining approvals and permits; the tendency of simplifying legal acts that results in unsolvable questions and gaps in their application; «end-of-the-pipe» model of tackling environmental problems; disregarding the difference between discharges by public utilities and industrial enterprises – water users; the lack of pollutant differentiation both by origin and the rate of environmental hazard. Despite the severity and complexity of the regulating system the state has practically distanced itself from the actual liability for improving environmental conditions. The major drawbacks of the mechanism of charging for pollutant discharges are as follows: the lack of legislative control; charging for any amount and any concentration of substances including the amounts that do not impact the permissible quality parameters; complementary dependence on the availability or lack of PDR and limits; inability of paying for discharges above PDR from cost of production; unreasonably large lists of discharged substances subject to charging; non-charging for the complex pollution indices (except BOD); the lack of incentive role in relation to many pollutants; the existence of potential double charge for one and the same discharge called compensation of damage to water bodies caused by the violation of the water law. The conclusion is drawn that the existing system of regulations and charges is not only useless, but also injures greatly the actual activities on rehabilitation of water bodies; and that integrated reforming the environmental legislation is needed.
