Resumo: Rapid urban and population growth has increased demand for drinking water. Consequently, large amounts of sludge are generated in the decanters of the Water Treatment Plants (ETA) as a result of the treatment process. This residue, when not disposed of correctly, can become a contaminant to the environment. The present work aims to present through a literature review study alternative forms for the application of ETA sludge in road paving with emphasis on the aggregate used for stabilization and leaching process, in order to evaluate an environmentally correct destination. Through the literature studied it is possible to conclude that sludge can be applied in the paving layers (base, sub-base and subbed), in bituminous concrete and concrete for the recomposition of sidewalks. With regard to stabilization, the use of cement, hydrated lime and soil is perceived. Regarding the leaching process, there is a greater presence of Mn, Fe, Al, Cd, Pb and Ni in several studies that contemplate this test.

En consecuencia, se generan grandes cantidades de lodos en los decantadores de las Plantas de Tratamiento de Aguas (ETA) como resultado del proceso de tratamiento. Este residuo, cuando no se elimina correctamente, puede convertirse en un contaminante para el medio ambiente. El presente trabajo tiene como objetivo presentar a través de un estudio de revisión de la literatura formas alternativas para la aplicación de lodos ETA en la pavimentación de carreteras con énfasis en el agregado utilizado para el proceso de estabilización y lixiviación, con el fin de evaluar un destino ambientalmente correcto. A través de la literatura estudiada es posible concluir que los lodos se pueden aplicar en las capas de pavimentación (base, sub-base y subbed), en hormigón bituminoso y hormigón para la recomposición de las aceras. Con respecto a la estabilización, se percibe el uso de cemento, cal hidratada y suelo. En cuanto al proceso de lixiviación, hay una mayor presencia de Mn, Fe, Al, Cd, Pb y Ni en varios estudios que contemplan esta prueba.O rápido crescimento urbano e populacional aumentou a demanda por água potável. Consequentemente grandes quantidades de lodo são geradas nos decantadores das Estações de Tratamento de Água (ETA) como resultado do processo de tratamento. Esse resíduo, quando não descartado corretamente pode vir a ser um contaminante para o meio ambiente. O presente trabalho objetiva apresentar por meio de um estudo de revisão de literatura formas alternativas para a aplicação do lodo de ETA em pavimentação rodoviária com ênfase no agregado usado para estabilização e o processo de lixiviação, afim de avaliar uma destinação ambientalmente correta. Por meio da literatura estudada é possível concluir que o lodo pode ser aplicado nas camadas da pavimentação (base, sub-base e subleito), em concretos betuminosos e concretos para a recomposição de calçadas. No que se refere a estabilização, percebe-se o emprego de cimento, cal hidratada e solo. Quanto ao processo de lixiviação, verifica-se a maior presença de Mn, Fe, Al, Cd, Pb e Ni em vários estudos que contemplam esse teste.Research, Society and Development2020-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/445810.33448/rsd-v9i7.4458Research, Society and Development; Vol. 9 No. 7; e786974458Research, Society and Development; Vol. 9 Núm. 7; e786974458Research, Society and Development; v. 9 n. 7; e7869744582525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4458/4204Copyright (c) 2020 Ana Millene dos Santos Silva, Eliezio Nascimento Barboza, Maria Fernanda da Cruz Silvainfo:eu-repo/semantics/openAccessSilva, Ana Millene dos SantosBarboza, Eliezio NascimentoSilva, Maria Fernanda da Cruz2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4458Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:18.358623Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
