1. REMOVAL OF BPA FROM LANDFILL LEACHATES USING FENTON-ADSORPTION PROCESS
The objective of this investigation was to identify and quantify the presence of Bisphenol-A (BPA) in raw and treated leachates with the Fenton-adsorption process. BPA is used as a monomer to produce epoxy resins and it is a compound classified as endocrine disruptor. For this reason, it is important to quantify its presence in effluents that will be dispose

2. IDENTIFICAÇÃO DE COMPOSTOS ORGÂNICOS EM LIXIVIADO DE ATERRO SANITÁRIO MUNICIPAL POR CROMATOGRAFIA GASOSA ACOPLADA A ESPECTROMETRIA DE MASSAS
The organic compounds present in leachate can contaminate soil, superficial and underground water, and the majority is considered harmful to the environment and human health. The objective of this study was to identify organic compounds present in landfill leachate located in Maringá-PR by gas chromatography coupled to mass spectrometry (GC-MS). The raw

3. Modelagem Matemática da produção e transporte de biogás em aterros sanitários / Mathematical modeling of production and transportation of biogas in landfills
The processes that occur within the landfill for the production of methane are the methane generation through biodegradation, transport of methane through a porous medium and sorption of methane through reactions with other compounds present in the landfill, especially oxidation. This work aims to develop a computer model to estimate the biogas production ra

4. Lixiviado de aterros sanitários brasileiros: estudo de remoção do nitrogênio amoniacal por processo de arraste com ar ("stripping") / Sanitary landfill leachate in Brazil: evaluation of ammonia nitrogen removal by air stripping process
Sanitary landfills are considered as the most appropriate way for final disposal of municipal solid wastes in Brazil, in the technical and economical point of view. Open dumps have been progressively substituted by well engineered and operated landfills. However, landfills still present environmental risks due to the gas emission and leachate production. Gas

5. Estudo da evaporaÃÃo de lixiviados de aterros sanitÃrios como alternativa tecnolÃgica de tratamento: testes em bancada
The leachate from landfill contains high pollution load and its composition gives large amounts of ammonia, chlorides, recalcitrant substances, organic and inorganic compounds. Such waste can cause negative effects on the environment and interfere with the performance of biological processes for their degradation. The choice of technology appropriate treatme

6. AvaliaÃÃo da influÃncia da composiÃÃo de resÃduos sÃlidos urbanos no comportamento de aterros simulados
O desenvolvimento de pesquisas, envolvendo aterros em escala real, apresenta alguns inconvenientes, como: custo elevado, grande nÃmero de variÃveis envolvidas no processo e a dinÃmica de operaÃÃo do aterro, que dificulta a obtenÃÃo sistemÃtica de dados sob condiÃÃes conhecidas ou controladas. Sendo assim, cÃlulas experimentais de pequenas dimensÃ

7. 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

8. 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
