Os resíduos sólidos gerados em estações de tratamento de água têm características inorgânicas, sendo eles os resíduos retirados da água bruta por meio de processos químicos e físicos e também os produtos utilizados no condicionamento da água e na coagulação para remoção dessas impurezas. Como alguns estudos apontaram para disposições semelhantes para os dois tipos de resíduos, apesar das características diferentes de cada um, a proposta deste trabalho foi a de avaliar a possibilidade de tratamento combinado desses resíduos, aproveitando as diversas vantagens de cada material e verificando os impactos que podem ser gerados no tratamento do efluente. Utilizando essa premissa, foi avaliado o potencial de utilização de um lodo adensado proveniente de uma ETA como auxiliar em uma ETE que apresenta uma etapa utilizando processo físico-químico de tratamento. O estudo e levantamentos apresentados nesse trabalho tiveram por propósito apontar para uma solução técnica viável para a disposição do lodo gerado na estação de tratamento de água (ETA), adensado na estação de tratamento de lodo (ETL), transportado e lançado na estação de tratamento de esgotos (ETE), no município de Itatiba. Com base no trabalho desenvolvido, foi possível confirmar que o adensamento de lodo em sacos de geotecido possibilita que a água deles drenada possa ser lançada em córregos, pois atende aos padrões de lançamento exigidos pelas leis vigentes; o lodo, adensado na ETL e lançado na ETE, não prejudicou a eficiência do tratamento dos esgotos quanto à remoção de carga orgânica e sólidos suspensos totais, principalmente porque o processo adotado também utiliza coagulantes. Contudo, o limitante para o aumento do lançamento é determinado pelas condições em que foram consideradas para o projeto da ETE, principalmente quanto a carga de sólidos e volume afluente / Abstract: Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical processes and also products used in the conditioning of water and coagulation. The wastes generated in sewage treatment plants are derived from biochemical reactions and from decomposition of organic matter present in wastewater. As some studies have pointed to similar disposal solutions for both types of waste, despite their different characteristics, the purpose of this study was to evaluate the possibility of combined treatment of such waste, using the many advantages of each material and checking the impacts that they could generate in the sewage treatment. Using this premise, the potential use of a thickened sludge from a water treatment plant as to assist in a wastewater treatment plant was evaluated. The study and surveys presented here had the purpose to point a viable technical solution for the disposal of sludge generated in a water treatment plant narrow in the sludge treatment plant, transported and released at sewage treatment plant in Itatiba, São Paulo, Brazil. Based on the work developed, it was confirmed that the thickening of sludge in geotec bags allows water drained from them to be released into rivers, because it meets the discharge Brazilian standards required; the thickened sludge did not impair the efficiency of sewage treatment on organic load removal or suspended solids removal, mainly because the process adopted also uses coagulants. However, limiting the increase in the release is determined by project conditions, especially as the influent volume and solids load / Mestrado / Saneamento e Ambiente / Mestre em Engenharia Civil

<p>Vi&scaron;e od 100 vrsta virusa ljudi i životinja se izlučuje u spolja&scaron;nju sredinu. Prisustvo ovih virusa u povr&scaron;inskim vodama reflektuje fekalnu kontaminaciju i ukazuje na<br />opasnost za zdravlje ljudi i životinja. Na području Srbije se ne prati prisustvo patogenih virusa u povr&scaron;inskim vodama, pa&nbsp; čak ni u vodama za piće, a nije uspostavljena&nbsp; ni&nbsp; metodologija ovih ispitivanja. Shodno tome, cilj disertacije je da se utvrdi i analizira prisustvo animalnih i humanih virusa u povr&scaron;inskim vodama primenom najsavremenijih metoda koncentrovanja i detekcije virusa. U okviru disertacije ispitano je prisustvo sledećih virusa u povr&scaron;inskim vodama na teritoriji Vojvodine: humanih adenovirusa (HAdV); norovirusa (NoV) i hepatitis A virusa (HAV), adenovirusa svinja (PAdV),&nbsp; poliomavirusa goveda (BPyV) i hepatitis E virus (HEV).</p><p>Ispitano je ukupno 108 uzoraka povr&scaron;inskih i otpadnih voda koji su prikupljani od oktobra 2012. godine do juna 2014. godine. U radu su primenjene najsavremenije metode koncentrovanja i detekcije virusa u vodi, koje se u Srbiji nisu koristile za ovu namenu. Sprovedenim ispitivanjima dokazano je da su animalni i humani virusi prisutni u povr&scaron;inskim vodama na području Vojvodine. Najče&scaron;će detektovan&nbsp; virus u povr&scaron;inskim vodama je humani adenovirus (42,4%), a potom norovirusi GII i GI (40,4% i 15,2%), adenovirus svinja (11,1%), poliomavirus goveda (7,1%) i hepatitis E virus (3,0%). U ukupno 9 testiranih uzoraka gradske kanalizacione vode najče&scaron;će je detektovan HAdV (44,4%), NoV GII i GI&nbsp; (66,7% i 22,2%), BPyV je detektovan u samo jednom od 9 uzoraka, a niti u jednom nisu detektovani PAdV i HEV. Hepatitis A virus nije detektovan u uzorcima, a eksperimentalno je potvrđeno da su metode primenljive i za detekciju ovog virusa. Na osnovu rezultata prinosa procesne kontrole i utvrđenog prisustva virusa u uzorcima,&nbsp; zaključeno&nbsp; je da se ove metode mogu veoma uspe&scaron;no koristiti za detekciju virusne kontaminacije&nbsp; povr&scaron;inskih voda. Izvr&scaron;ena je igenotipizacija virusa iz odabranih uzoraka metodom sekvenciranja dela virusnog genoma. Indirektno je potvrđeno da su infekcije&nbsp;&nbsp; detektovanim virusima prisutne u populaciji životinja i ljudi. Prisustvo virusa u&nbsp;&nbsp; povr&scaron;inskim vodama i uzorcima gradske kanalizacije odražava infektivni status stanovni&scaron;tva, ali predstavlja i značajan rizik za zdravlje životinja i ljudi na području koje gravitira ispitanim vodama.&nbsp;</p> / <p>Over 100 types of pathogenic viruses are excreted in human and animal wastes. The presence of human and animal pathogenic enteric viruses in water environments reflects fecal contamination and indicates a risk to public health.&nbsp; Republic of Serbia does not implement surveillance for the presence of pathogenic human and animal viruses in surface waters and even in drinking water, neither is the established methodology of these studies in any institution in Serbia.&nbsp; Accordingly, the aim of the study was to determine and analyze the presence of human and animal viruses in surface water,&nbsp; using the latest methods&nbsp; of&nbsp; concentration and detection of the viruses.&nbsp; Within the dissertation examined the presence of the following viruses in surface waters in Vojvodina:&nbsp; Human adenoviruses&nbsp; (HAdV), noroviruses (NoV)&nbsp; and hepatitis A virus), Porcine adenovirus (PAdV) and Bovine polyomavirus (BPyV)&nbsp; and&nbsp; Hepatitis E virus (HEV).<br />A total of 108 samples of surface water and waste water were collected from October 2012 to June 2014. The paper are applied the most advanced methods and the concentration of virus detection in water, which in Serbia are not used for this purpose. The conducted tests have proven that the animal and human viruses present in surface waters in Vojvodina. The most commonly detected virus in surface water was human adenovirus (42.4%), followed by Norovirus GI&nbsp; and GII (40.4% and 15.2%),&nbsp; Porcine adenovirus&nbsp; (11,1%),&nbsp; Bovine polyomavirus&nbsp; (7.07%) and hepatitis E virus (3,0%).<br />In total of&nbsp; nine analysed sewage samples human adenovirus was detected in 44,4%&nbsp; of&nbsp; samples. The prevalence of norovirus GII and GI in sewage&nbsp; samples was&nbsp; 66,7%&nbsp; and 22,2%. Bovine&nbsp; polyomavirus was detected in one of nine samples while porcine adenovirus and hepatitis E virus were not detected in any of analyzed samples.&nbsp; Hepatitis A virus was not detected in samples, but&nbsp; it has been experimentally confirmed that the methods applicable for detection of the virus. Based on the results of process control and yield determined the presence of virus insamples, it was found that these methods can be successfully used to detect viral contamination of surface waters. Also, in these study was performed genotyping of viruses from selected samples by sequencing a part of the viral genome. Indirectly it is confirmed that the infection detected viruses present in a population of animals and humans. The presence of virus in samples of surface water and urban sewage reflects the infectious status of the population, but also constitutes a significant risk to the health of animals and people in the area that gravitates with tested waters.</p><p>&nbsp;</p>

This work is based on the occurrence of drug residues in the environment. This study is focused on the development and optimization methods for determination of selected drugs in the surface water, aquatic sediment and sewage sludge from waste water treatment plant. From the group of drugs were chosen antibiotics. Antibiotics presented in the environment can cause adverse effects including toxic effects, immunity disorders and indirect bioalteration effects. Sulfonamide antibiotics, which are used in the treatment of urinary and respiratory tract infections as well as in the treatment of other infectious diseases, were chosen as a target compounds. Three optimized analytical methods for determination of sulfonamide antibiotics were developed. For the optimization of extraction were tested: solid phase extraction, pressurized solvent extraction, microwave extraction and ultrasonic extraction. For the final analysis was used liquid chromatography with two detectors - diode array detector and mass spectrometer. These optimized methods were applied for the analysis of real samples. The surface water and sediment samples were collected from two Moravian rivers (the Svratka river and the Svitava river). Samples of sewage sludge were collected from waste water treatment plant Brno-Modřice. Fish samples from the Svratka river were also collected. It was observed that all the selected sulfonamide antibiotics are present in real sediment samples (ug.kg-1). Simultaneously presence of some target analytes in real surface water (ug.l-1) and in sewage sludge (ug.kg-1) samples has been confirmed. In samples of surface water from the Svitava river and in fish samples sulfonamide antibiotics were not detected or their concentrations were below the limit of detection.
