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.

Analysis of the «Methods of developing standards for permissible discharges of substances and microorganisms into water bodies for water users» against the background of the water protection legislation
(for discussion)

Summary

The analysis of the current edition of the «Methods of developing standards for permissible discharges of substances and microorganisms into water bodies for water users», approved by the Order of the Ministry of Natural Resources of Russia dated December 17, 2007 No. 333 for consilience and compliance with the regulations of the water protection legislation, is carried out. Uncertainty of the application of the Methods in the conditions of the impact of natural and anthropogenic factors that are independent of a specific water user on the quality of water has been identified. The provisions of the Methods contradict the principles of regulating the impact on water bodies based on the best available technologies shown on the examples of approved process indicators of the concentrations of various industrial pollutants in wastewater. An analysis of the system of regulating the permissible impact on water bodies and the geographical differentiation of water quality standards within the boundaries of the Russian Federation, together with the system of water quality targets, also showed that the Methods do not comply with the basic principles of the water protection legislation.

Introduction of advanced technologies during the construction and upgrade of the wastewater treatment facilities operated by Mosvodokanal JSC

Summary

The experience of introducing advanced technologies for wastewater treatment at the wastewater treatment facilities in Moscow is considered; process flow schemes for the structures of different capacities are described. Since the late 1990s, the Engineering and Technology Center of Mosvodokanal JSC has been working on the development and introduction of advanced wastewater treatment technologies with the removal of nutrients. Since the composition of wastewater differs at different treatment facilities, it is not possible to “transfer” foreign technologies without correction and adaptation; moreover, sometimes the development of technology “from square one” is required. For more than 20 years, a stepwise introduction of advanced technologies has been carried out at the Moscow treatment facilities of South Butovo and Zelenograd, at the nutrients removal block at the Lyuberetskie wastewater treatment facilities, at the new block of the Kurianovskie Wastewater Treatment Facilities. At present, the reconstruction of the Lyuberetskie Wastewater Treatment Facilities (old and new blocks) is underway, the reconstruction of the old part of the Kurianovskie Wastewater Treatment Facilities is planned, the treatment facilities of the Troitsk and Novomoskovsk administrative districts in Moscow have been under upgrade. The experience of Mosvodokanal JSC was used in the development of an ITS 10-2015 reference book of the best available technologies. A variety of process solutions provides for ensuring the standard quality of effluent for the conditions of different facilities.

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.

Criterial approach to substantiation of the best available techniques for engineering protection against hazardous techno-natural processes

Summary

Prediction of measures and construction of facilities for engineering protection from hazardous processes has a number of specific features that should be borne in mind while developing a method for substantiating the best available techniques. The mathematical tools that provide for substantiating the choice of a technology for engineering protection from hazardous techno-natural processes, that can be assigned to the best available techniques, are under development. One of the approaches is presented that allows, on the basis of quantitative assessments, to substantiate the choice of an option of engineering protection against hazardous techno-natural processes. This approach is based on the expert-analytical method for assessing the risk from hazardous natural-technogenic processes that has been widely used in recent years. Mathematical tools have been proposed that provide for reasonably approaching the choice of the best available technique for engineering protection against hazardous techno-natural processes, taking into account the capabilities of the owner, his position in the current situation and development prospects.

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.

Best available technologies of wastewater treatment:  implementation experience of «Mosvodokanal» JSC

Summary

Owing to the transfer to process standardization from 2019 (Federal Law No. 219-FZ) natural resource users are bound to introduce the best available technologies. Advanced technologies of municipal wastewater treatment ensuring the removal of nitrogen and phosphorus have been used in Russia at less than 10% of the wastewater treatment facilities. When transferring to process standardi­zation many water utilities will face the problem of upgrading wastewater treatment facilities. Successful practical experience of water utilities where BATs have been already used at wastewater treatment facilities will be useful for choosing the optimal process flow scheme. The introduction of advanced wastewater treatment methods has been a priority task for «Mosvodokanal» JSC. For a long period the company has developed and adapted to the conditions of the Moscow wastewater treatment facilities the process flow scheme of wastewater treatment with the removal of nutrients (nitrogen and phosphorus) which is the best available technology. This made it possible to introduce this technology at the Lyuberetskie and Kuryanovskie wastewater treatment facilities – the largest and extremely large-scale facilities as well as at small- and mid-scale wastewater treatment plants in Minzag and Shchapovo settlements (Prefecture of Troitsky and Novomoskovsky Administrative Districts, Moscow). Experts of «Mosvodokanal» JSC developed a pre-design concept of the reconstruction of the aeration tanks at the treatment facilities of Cherepovets and the local treatment facilities of the Optina Pustyn monastery (Kozelsk, Kaluga Region) with the introduction of nutrients removal technology. The practical experience gained in «Mosvodokanal» JSC shows that the best available technologies have been developed, can be introduced and operate successfully.

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.

Switch over to the technologic regulation of effluent discharges from municipal wastewater treatment facilities: ten years track record and recommendations after the adoption of the complete package of regulatory legal acts

Summary

On behalf of the participants in the process, a description of the concept of technological regulation of wastewater discharges from settlements, the development and adoption of legislative acts for the switch over to the new system is given. The paper dwells upon the adoption of the final regulatory legal act (Government Decree of September 2020 No. 1430), completing the development of a legislative framework designed to put an end on the use of fishery maximum permissible concentrations as wastewater discharge standards. Explanations are given on the relationship between the status of the provisions of the updated information and technical reference book ITS 10-2015 and the specified resolution in different applications. Recommendations are given for municipal wastewater treatment facilities and engineering companies on priority actions in the preparation and drawing up of applications for integrated environmental permits and design specifications and estimates according to the new regulations. Attention is drawn to the fact that switching over to a new regulation system requires assigning a category to a water body (performed by Rosvodresursy); otherwise the application of the process parameters established by the Government of the Russian Federation is impossible. The specific features of designing treatment facilities in the new regulation system are noted.
