25. Study of the integrated management of urban solid waste at the Tietê-Jacaré basin (UGRHI-13) / Estudo da gestão integrada dos resíduos sólidos urbanos na bacia Tietê-Jacaré (UGRHI-13)
Os resíduos sólidos podem poluir e contaminar as águas superficiais e subterrâneas, pela migração de lixiviado gerado em aterros e lixões, o que pode colocar em risco a saúde pública e o ambiente. Assim, o objetivo deste estudo foi analisar a gestão dos resíduos sólidos urbanos na bacia hidrográfica Tietê-Jacaré, pertencente a 13a Unidade de G

26. Slow sand filter in the treatment of leachate of the sanitary landfill of Limeira -SP / Sistema de filtração lenta no tratamento de percolado do aterro sanitario de Limeira-SP
The final disposition of solids residues is a practice that still brings serious impacts to the environment. In sanitary landfill, the residues goes through physical, chemical and biological decomposition processes, generating into a gas phase (mainly composed by CH4 and CO2) and a liquid phase known as leachate. The waste leachate is a liquid with high poll

27. Estudo comparativo das caracterÃsticas dos lÃquidos percolados gerados no Aterro Metropolitano â PB e no Aterro da Muribeca â PE
The way of final disposition used for homely urban solid waste in Brazil and throughout the world has been sanitary embankment, which can be applied for both small and big communities. It is important to mention in this method, the treatment of the liquids that are not generated inside the heap of refuse, named leachate, which produces the percolate when mix

28. Tratamento de lixiviado através de filtro anaeróbio associado a membrana de microfiltração
Nowadays, the use of membrane bioreactors (MBRs) has been researched in many places of the world to treat different kinds of wastewater. The use of MBRs has advantages over other processes when the main focus is on the reuse of wastewater, small areas for wastewater treatment plant or restricted laws conditions. Commonly, the MBRs have been designed with sus

29. Tratamento de chorume de aterro sanitario usando eletrolise foto-assistida / Treatment of landfill leachate by photo-assisted electrolysis
Sanitary landfills are the major method used today for the disposal and management of municipal solid waste. Decomposition of waste and rainfall generate leachate at the bottom of landfills, causing groundwater contamination. The leachate is a dark grey, foul smelling solution and it can be considered a complex effluent, often containing organic compounds, h

30. Investigação geoambiental em áreas de disposição de resíduos sólidos urbanos utilizando a tecnologia do piezocone. / Geoenvironmental site investigation in waste disposal sites using the piezocone technology.
The major purpose of this dissertation is to study the applicability of the piezocone technology for geoenvironmental site investigation of tropical soils. Two waste disposal sites were investigated: a deactivated dumpsite in Ribeirão Preto and a sanitary landfill in Bauru, in São Paulo State, Brazil. Other in situ and laboratory tests were carried out in

31. AVALIAÇÃO EM LABORATÓRIO DO TRANSPORTE DE CONTAMINANTES NO SOLO DO ATERRO SANITÁRIO DE SAUÍPE/BA / LABORATORY ASSEISMENT OF SOIL CONTAMINANT TRANSPORT IN SAUIPE MUNICIPAL WASTE LANDFILL
The purpose of this thesis is to present an evaluation of the mobility of leachate in the soil of Sauípe s Sanitary Landfill, located in the municipality of Entre Rios, in the State of Bahia. The study is based on experimental laboratory results and on literature data, which have been used for predicting the contaminant transport and the main mechanisms of

32. Estudo de compostos orgânicos em lixiviado de aterros sanitários por EFS e CG/EM
The main purpose of this work was the qualitative study of organic compounds in landfill leachate. The samples were collected from a sanitary landfill located at Gravataí, a southern Brazilian city, that receive both, industrial and domestic refuse. The samples were submitted to solid phase extraction (SPE) with XAD-4 resin as the stationary phase. The inst

33. Compactação e compressibilidade de resíduos sólidos urbanos / Compaction and compressibility of municipal solid waste
The objectives of this research were to: (i) study the compaction characteristics of municipal solid waste (MSW); (ii) evaluate the compression mechanisms of MSW and its response to a surcharge (waste test fill) over an existing landfill; (iii) develop a computer program for landfill settlement predictions. A waste test fill with a volume of about 24,400 M P

34. Bacterial Population Development and Chemical Characteristics of Refuse Decomposition in a Simulated Sanitary Landfill
Population development of key groups of bacteria involved in municipal refuse conversion to methane was measured from the time of initial incubation through the onset of methane production. Hemicellulolytic bacteria, cellulolytic bacteria, hydrogen-producing acetogens, and acetate- and H2-plus-CO2-utilizing methanogens were enumerated by the most-probable-nu
