С момента перехода государства на новую экономическую модель развития социально значимые отрасли остались в тени «локомотивов» экономического развития – топливно-энергетического и минерально-сырьевого комплексов. Отрасли народного хозяйства, не имеющие коммерческого интереса, отмирали полностью или сжимались до размеров возможной минимальной окупаемости. Данные изменения затронули и отрасль жилищно-коммунального хозяйства, в частности водопроводно-канализационное хозяйство. Катастрофическое состояние отрасли в настоящее время требует особого внимания и особых решений со стороны всех участвующих и заинтересованных сторон: органов государственной и муниципальной власти, органов контроля и надзора, операторов систем водопроводно-канализационного хозяйства, коммерческих организаций, высшей школы, профильного научного сообщества и населения. Одна из базовых отраслей народного хозяйства не должна находиться в таком состоянии и, несмотря на отсутствие экономической стабильности, необходимо сделать ее восстановление приоритетной государственной задачей, направив на это максимальные материальные и интеллектуальные ресурсы страны. Приведен пример концессионного соглашения, которое иллюстрирует один из возможных путей продления ресурса городского канализационного хозяйства с предельным износом. Since the transition of Russian Federation to a new economic model of development, socially significant industries have remained in the shadow of the «locomotives» of the economic development, i. e., the fuel and energy and mineral resource sectors. Branches of the national economy that had no commercial interest died out completely or shrank to the size of a possible minimum payback. These changes also affected the housing and utilities sector, in particular, the water supply and wastewater disposal systems. The catastrophic state of the industry currently requires special attention and special decisions on the part of all the stake holders: the state and municipal authorities, control and supervision bodies, operators of water and wastewater utilities, commercial organizations, higher education, the relevant scientific community and population. One of the basic sectors of the national economy should not be in such a state and, despite the lack of the economic stability, its restoration should be a priority state task directing the maximum material and intellectual resources of the country. An example of a concession agreement is given that can be a possible way to extend the resource of an urban wastewater disposal system with a wear limit.

Из-за неравномерности распределения водных ресурсов по территории России многие населенные пункты и даже города не имеют своих источников водоснабжения и водоемов, куда можно было бы сбрасывать очищенные сточные воды. Для решения этой проблемы проектируются, строятся и развиваются групповые и районные системы водоснабжения и водоотведения. Протяженность таких систем насчитывает сотни и даже тысячи километров. На их строительство и эксплуатацию ежегодно требуются значительные финансовые средства. Поэтому вопросы выбора трасс, состава сооружений и особенно способов транспортировки воды и сточных вод, обоснования мест расположения водозаборов и очистных сооружений являются актуальными и требуют особого внимания и технико-экономического анализа проектных вариантов. Предлагается методика комплексной оптимизации параметров систем водоснабжения и водоотведения, позволяющая определять наилучшие способы транспортирования воды и стоков (трубопроводами либо в цистернах автомобилей), места устройства водозаборов, водопроводных и канализационных очистных сооружений, оптимальные трубопроводные трассы и автомобильные маршруты между этими сооружениями и абонентами. Due to the uneven distribution of water resources across the territory of Russia, many communities and even cities lack own water supply sources and water bodies where effluents could be discharge into. To address this problem, group and district water supply and wastewater disposal systems are designed, built and developed. The length of such systems is hundreds and even thousands of kilometers. Significant financial resources are required annually for their construction and operation. Therefore, the issues of the choice of routes, composition of the structures and especially methods of transporting water and wastewater, justification of locating water intakes and treatment facilities are relevant and require special attention and technical and economic analysis of design options. A method is proposed for the comprehensive optimization of the parameters of water supply and wastewater disposal systems that will provide for determining the best ways of transporting water and wastewater (by pipelines or in road-tankers), location of water intakes, water supply and wastewater treatment facilities, optimal pipeline routes and auto routes between these structures and customers.

Организации водопроводно-канализационного хозяйства в рамках технологических процессов водоотведения должны обеспечивать дезинвазию очищенных сточных вод и осадков, образующихся в результате их очистки. В соответствии с пунктом 1.2 СанПиН 3.2.3215-14 Профилактика паразитарных болезней на территории РФ , санитарные правила устанавливают требования к комплексу организационных, санитарно-противоэпидемических (профилактических) мероприятий, проведение которых направлено на предупреждение возникновения и распространения паразитарных заболеваний. Проведена оценка нормативных документов по дезинвазии объектов окружающей среды, а также решений по судебным делам в части ее проведения. Выявлены разногласия в документах по проведению дезинвазии, в связи с чем направлены обращения в различные организации с предложением гармонизировать правила с целью исключения разночтений. Изучены индустриальные методы дезинвазии осадка сточных вод. Показано, что происходит необоснованное навязывание препарата Бингсти .Within the frames of the wastewater disposal processes water and wastewater utilities shall provide for the disinvasion of effluents and wastewater sludge generated in the process of wastewater treatment. In accordance with paragraph 1.2 of SanPiN 3.2.3215-14 Prevention of parasitic diseases in the territory of the Russian Federation , the sanitary rules set out the requirements for a comprehensive set of organizational, sanitary and anti-epidemic (preventive) measures, that are aimed at preventing the occurrence and spread of parasitic diseases. The assessment of regulatory documents on the disinvasion of environmental objects, as well as judicial decisions regarding its implementation, was carried out. Controversies were revealed in the regulatory documents, and appeals were sent to various organizations with a proposal to harmonize the rules in order to exclude discrepancies. Industrial methods for disinvasion of wastewater sludge were studied. It is shown that there is an unreasonable aggressive selling of Bingsti ineffective product.

We document and show a state-of-the-art methodology that could allow geoheritage sites (geosites) to become accessible to scientific and non-scientific audiences through immersive and non-immersive virtual reality applications. This is achieved through a dedicated WebGIS platform, particularly handy in communicating geoscience during the COVID-19 era. For this application, we selected nine volcanic outcrops in Santorini, Greece. The latter are mainly associated with several geological processes (e.g., dyking, explosive, and effusive eruptions). In particular, they have been associated with the famous Late Bronze Age (LBA) eruption, which made them ideal for geoheritage popularization objectives since they combine scientific and educational purposes with geotourism applications. Initially, we transformed these stunning volcanological outcrops into geospatial models—the so called virtual outcrops (VOs) here defined as virtual geosites (VGs)—through UAV-based photogrammetry and 3D modeling. In the next step, we uploaded them on an online platform that is fully accessible for Earth science teaching and communication. The nine VGs are currently accessible on a PC, a smartphone, or a tablet. Each one includes a detailed description and plenty of annotations available for the viewers during 3D exploration. We hope this work will be regarded as a forward model application for Earth sciences' popularization and make geoheritage open to the scientific community and the lay public.

The large scale of the contamination by the former carbo-chemical industry in Germany requires new and often interdisciplinary approaches for performing an economically sustainable remediation. For example, a highly toxic and dark-colored phenolic wastewater from a lignite pyrolysis factory was filled into a former open-cast pit, forming a large wastewater disposal pond. This caused an extensive environmental pollution, calling for an ecologically and economically acceptable strategy for remediation. Laboratory-scale investigations and pilot-scale tests were carried out. The result was the development of a strategy for an implementation of full-scale enhanced in situ natural attenuation on the basis of separate habitats in a meromictic pond. Long-term monitoring of the chemical and biological dynamics of the pond demonstrates the metamorphosis of a former highly polluted industrial waste deposition into a nature-integrated ecosystem with reduced danger for the environment, and confirmed the strategy for the chosen remediation management.

Осадки городских очистных канализационных сооружений являются самым массовым технологическим отходом, создающим проблемы утилизации для любого города. Рассмотрены возможные методы обработки осадков сточных вод на городских очистных канализационных сооружениях городского округа Самара с целью их последующей утилизации. Обозначены причины и приведены документальные подтверждениянекорректности возложения ответственности за обращение с такими отходами только на организации водопроводно-канализационного хозяйства. Рассмотрен способ захоронения обезвоженного осадка сточных вод в обвалованном полигоне. Установлено, что обработанные на очистных сооружениях осадки относятся к V классу опасности для окружающей среды. Обработанные, стабилизированные, подсушенные, обезвреженные отходы осадков сточных вод (малоопасный осадок с песколовок при очистке хозяйственно-бытовых и смешанных сточных вод, практически не опасный осадок с песколовок при очистке хозяйственно-бытовых и смешанных сточных вод и избыточный ил биологических очистных сооружений в смеси с сырым осадком) могут быть использованы в качестве наполнителей бетонно-цементных смесей и органоминеральных удобрений или переданы для утилизации сторонним организациям. Sludge from the municipal wastewater treatment facilities is the most massive technological waste that causes trouble for any city. Possible methods of wastewater sludge treatment at the municipal wastewater treatment facilities of the Samara Urban District with the purpose of its further utilization are considered. The reasons are indicated and documentary evidence of the incorrectness of assigning the responsibility for processing such wastes only to the water and wastewater utilities is provided. The method of landfilling dewatered wastewater sludge in a ridged landfill is considered. It has been established that the sludge processed at the wastewater treatment facilities is referred to the V class of environmental hazard. Sludge subjected to the treatment, stabilization, drying and neutralization (low hazardous sludge from grit chambers for domestic and mixed wastewater treatment; almost non-hazardous sludge from grit chambers for domestic and mixed wastewater treatment and excess sludge from biological treatment facilities mixed with raw sludge) can be used as fillers for concrete-cement mixtures and organo-mineral fertilizers or transferred for disposal to outside companies.

Nationally, 4% of electricity usage goes towards moving and treating water and wastewater. The energy intensity of the water and wastewater utility sector is affected by many factors including water source, water quality, and the distance and elevation that water must be transported. Furthermore, energy accounts for 10% or more of a utility’s total operating cost, suggesting that energy savings can account for significant cost savings. Better knowledge of where and when energy is used could support strategic energy interventions and reveal opportunities for efficiency. Accordingly, this investigation quantifies energy intensity by process and type, including electricity and natural gas, and explores the time-varying nature of electric energy consumption for potable water distribution using the Austin Water Utility (AWU) in Austin, Texas as a case study. This research found that most of energy consumed by the AWU is for pumping throughout the distribution network (57%) and at lift stations (10%) while potable water treatment accounts for the least (5%). Though the focus is site specific, the methodology shown herein can be applied to other utilities with sufficient data.

Abstract: Life cycle assessment (LCA) is a tool to evaluate environmental impacts based on products of a process. This research is a case study of wastewater treatment facilities of ERTC (Environmental Resources Training Center), SIUE University, based on available data for two semi-annual sludge quantities (year 2015) from sludge management report. The aim of this study is to compare set of possibilities for a wastewater treatment facility at ERTC. The simulation has been done through SimaPro model. Electricity and methane were considered and the cumulative weight of their impacts has been investigated. Total solids for two semi-annual sludge has been fed to the model in kilogram and different production (electricity and methane) configuration were investigated. The most plausible configuration based on the cumulative environmental impact proposed as best practical solution.
