Environmental Considerations of Large Wastewater Treatment Plants – the City of Niš Case Study
Facta Universitatis, Series: Working and Living Environmental Protection, 2019
Nowadays, the Republic of Serbia is at the bottom of the scale of European countries in terms of public utility equipment of the respective communal infrastructure particularly within the area of wastewater collection and treatment. The current situation in the area of water resources management in the Republic of Serbia indicates that the basic problems are insufficient construction of sewerage infrastructure in cities, i.e. insufficient coverage with the sewerage network of users connected to either public or private water supply network, followed by an insufficient number of constructed and operative wastewater treatment plants. In this sense, a particular problem is a requirement for relatively large initial investments in wastewater collection and treatment sector. Also, a special difficulty is the low price of delivered and channeled water within the existing system of public utilities, which is insufficient to provide maintenance of the existing water supply and sewage system...
Concerns and Challenges on Wastewater Treatment Capacities Development in Romania
Analele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie, 2018
Our previous research has highlighted the importance and the problems of the development for the environmental infrastructure, namely of the Romanian water and wastewater networks, in order to attract and capitalize the allocated European funds. Therefore, in the present paper we deal these aspects from a more synthetic and historical outlook. In Romania, one of the most obvious characteristics concerning the general situation of the environment refers to the striking deficiencies in the environmental infrastructure, especially in the field of wastewater in urban areas and water supply and sewerage in rural areas. Nevertheless, historical and conceptual issues in the paper analyse how, despite its current development lag, in Romania, the concern for implementing and developing of wastewater treatment technology began over a hundred years ago. Thus, the objective of the research is to highlight and analyse some economic concerns and challenges of developing the wastewater infrastruct...
How Sustainable Is Our Wastewater Treatment?
The sanitation and environmental problems related to human activities can be traced at least around 2 500 years back, with written evidences both in the Old Testimony and the Greek culture. Thus in this perspective the matter is by convention an acknowledged problem since long. On the other hand our modern treatment systems of wastewater have far more recent roots. As an example, this year the very widespread biological treatment based on activated sludge celebrates it 100 year anniversary. In this perspective we may see a fundamental need to discuss and scrutinize the current systems in a “sustainable” perspective. A challenge for the technical society is to provide some “quantified” criteria on the concept sustainability. The wastewater treatment systems as we know them and develop them may be addressed by applying four major “sustainability” criteria: 1) The sustainability from major sanitation viewpoints; 2) The sustainability from environmental viewpoints; 3) The financial sustainability for the technical systems; (4) The sustainability with respect to adopting the systems into a more or less consistently changing society.
THE ROLE OF SUSTAINABLE DEVELOPMENT IN WASTE WATER TREATMENT MANAGEMENT
Sustainable development plays a key role in the survival of mankind. This is reflected in the management of resources as well as harmonizing of the human and other materials available to man. Waste water management and treatment technology is vital in achieving both goal 7 of the Millennium Development Goals that is, environmental sustainability and the Sustainable Development Goals 6 which dwells on access to adequate and equitable sanitation and hygiene for all. Waste water treatment is essential in environmental management. Waste water treatment can be defined as the proportion of wastewater that is treated, in order to reduce pollutants before being discharged to the environment, by level of treatment. This work tries to explain the role of sustainable development in waste water treatment management. The major focus is to analyze Don Parker General Enterprise Limited, their effluent treatment facility. Don Parker General Enterprise Limited is based in Warri-Yowonron college road, opposite yowonron college , Delta State, Nigeria, which is one of the developing countries of the world. Don Parker General Limited uses integrated activated carbon sludge process for their effluent treatment. This work will discuss briefly process technology involved in waste water treatment as practiced by Don Parker General Limited the outcome of the laboratory sample taken on the 4 th July, 2014 and analyzed between 4 th July-15 th July, 2014 and overall link it with sustainable development.

Corresponding author (ahospido@usc.es) cals to facilitate the water removal turned to have an influence on the environmental performance so attention to this should be paid in addition to the energy consumption associated. Conclusions and Recommendations. Four WWTPs of capacity ranging from 75,000 to 125,000 inhabitants were evaluated in order to get more knowledge of their environmental performance. Data on material and energy consumption as well as characterisation of the water and the sludge entering and leaving the facilities were collected from the facilities in order to build the inventory required to perform the environmental assessment. The comparison performed among the four facilities made possible the definition of a less environmentally damaging WWTP, where secondary treatment at the water line as well as filter band and anaerobic digestion at the sludge line should be included. As mentioned, this study is part of a research project in which twenty treatment plants (divided in groups according to their capacity of treatment) are being evaluating. At the present time only results from the study of those from the highest populated areas were considered. On-going research is focused on the analysis of the plants representative for less populated areas.
Perspective on Implementation of the Eu Urban Waste Water Treatment Directive in Serbia
2018
This paper presents the results of a comparative analysis of the sewerage connection rates in Europe and Serbia with and without wastewater treatment, including the primary, secondary and tertiary level. This comprises a comparative analysis of industrial development and sewerage connection rates in Finland and Serbia, with wastewater treatment, as well as an analysis of the perspective on the consistent implementation of the Waste Water Directive in Serbia in the context of the economic obligations arising therefrom. The aim of the paper is to analyse the Serbian perspective in the field of wastewater treatment during the harmonisation and after the completed EU accession process. The concluding part of the paper refers to the need to review priorities in this area from the standpoint of defining Serbia’s negotiating position in the EU accession process.

The aim of the paper was to determine the operational efficiency and environmental impact of five small wastewater treatment plants (WWTPs) in Ukmergė district. The efficiency of these WWTPs, reconstructed by applying the same vertical flow labyrinth technology was calculated according to the most important pollution indicators: biochemical oxygen consumption in 7 days (BOD7), total phosphorus (TP) and total nitrogen (TN) in period 2017-2020. It was found that the lowest operational efficiency of Taujėnai wastewater treatment plant was according to BOD7 (94-96%). The lowest treatment efficiency of total nitrogen was determined in Dainava WWTP (88-95%). The highest treatment efficiency according to total phosphorus was in Šventupė WWTP (86-92%), the lowest in Žemaitkiemis WWTP (72-85%). In order to evaluate the impact of wastewater treatment plants on the environment, their Life Cycle Assessment (LCA) was performed. Sludge from wastewater treatment process has been found to have the highest environmental impact and fuel consumption for transport the lowest. Of the five wastewater treatment plants examined, the Vidiškiai wastewater treatment plant has the largest impact on the environment, and Šventupė WWTP has the lowest.

The paper gives an analysis of water and waste management sector in the Republic of Croatia based on principles of ecological engineering. It evaluates the public utilities service sector which has a long tradition in Croatia and it outlines the future reform with the aim of increasing its efficiency. Particularly, it assesses the role of the company Croatian Waters, a specific entity the counterpart of which could hardly be found in other countries. The author is urging for innovative and environmentally-friendly decentralized solutions for wastewater treatment owing to low share of urban population, the need to protect groundwaters, surface waters and the sea, affordable cost and feasibility of phased construction, with small-scale plants for reuse of material and energy value from waste. The author identifies present responses in DPSIR framework and proposes a set of responses that would be more sustainable. Utilities services should be perceived within wider environmental protec...
Sustainability Assessment of Municipal Wastewater Treatment
World Academy of Science, Engineering and Technology, International Journal of Civil and Environmental Engineering, 2017
Abstract—In this paper, our methodology to assess sustainability of wastewater treatment technologies in Egypt is presented. The preliminary list of factors to be considered, as well as their ranking listed. The factors include, but are not limited to pollutants removal efficiency and energy consumption under the environmental dimension, construction cost, operation and maintenance costs and required land area cost under the economic dimension and public acceptance, noise and generating job opportunities for local residents. This methodology is intended to be a user-friendly screening tool to support the decision making process when investigating different wastewater treatment technologies in Egypt. Based on the research work results presented in this paper, it can be generally concluded that the categorization of some of the social and environmental aspects of sustainability is subjective and highly dependent on the local conditions and researchers’ background.
