o:1079 Baseline and options for design of wastewater treatment plants as a part of large sewerage infrastructure: case study Veliko Selo (Belgrade Sewerage System) en Abstract: For adequate dimensioning of wastewater treatment facilities, it is necessary to obtain and analyze the most reliable data on the quantity and quality of wastewater, with all necessary basic parameters for assessing the hydraulic and mass load of future process units and defining their capacity. To that end, the project of the construction of a collector system (interceptor) and a wastewater treatment plant for the Belgrade Central Sewerage System site included collection, systematization and analysis of existing data on the quantity and quality of wastewater, additional measurements of quantities and testing of wastewater quality, systematization and interpretation of the results, analysis of demographic data, assessment of future system load and the development of a mathematical models of the sewerage system using EPA SWMM package, as well as of transport of polluting substances in the natural recipients using RMA2/RMA4 through the SMS package. Final output is the baseline for the wastewater treatment plant of the Belgrade Central Sewerage System, as presented in this paper. The relevant legislation, focusing on two main outputs in terms of environmental protection of wastewater treatment – effluent and treated sludge, was analyzed individually, as well as considering interrelations between the provisions of legal documents. Four appropriate concepts for the wastewater treatment plant were singled out of a wider array of modern engineering solutions proven in practice, based on the analysis of legal and logistical constraints and pitfalls. 1552100 978-86-82565-55-0 2022-12-13T14:16:48.611Z 44 no 46 David Mitrinović Institut za vodoprivredu "Jaroslav Černi" 0000-0002-8097-2998 Natalija Pavlović Institut za vodoprivredu "Jaroslav Černi" person Žarko Sretenović Institut za vodoprivredu "Jaroslav Černi" person Fabian Fenoglio SUEZ Tour CB21 – 16 place de l’Iris, 92040 Paris La Défense – France person Benoit Samanos SUEZ Tour CB21 – 16 place de l’Iris, 92040 Paris La Défense – France person Miodrag Popović Institut za vodoprivredu "Jaroslav Černi" person 0000-0001-7544-4130 application/pdf 14115690 https://unilib.phaidrabg.rs/o:1079 no yes 1 70 92000004 71A04 Contemporary Water Management: Challenges and Research Directions, Proceedings of the International Scientific Conference in the Honour of 75 Years of the Jaroslav Černi Water Institute, October 19-20 2022, Belgrade 377 396 Jaroslav Černi Water Institute 2022 Received: September 9, 2022 Revision: September 22, 2022 Accepted: September 26, 2022
