<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG /> </o:OfficeDocumentSettings> </xml><![endif]--><span style="font-size: 12.0pt; line-height: 115%; font-family: 'Times New Roman','serif'; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: PT-BR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">O consumo de água vem aumentado significativamente, devido ao crescimento populacional, desenvolvimento industrial e expansão do cultivo irrigado. Observa-se uma crescente produção de esgotos sanitários que são lançados diariamente nos corpos receptores naturais.<span style="mso-font-kerning: 14.0pt;"> Um dos requisitos básicos para se preservar o Meio Ambiente, mais precisamente a qualidade das águas, é o desenvolvimento de sistemas de coleta e tratamento de esgotos domésticos eficientes. </span>Existem diversas formas de tratamento que buscam melhorar a qualidade e possibilitar o reuso de efluentes, dentre elas, está escoamento superficial, que têm se mostrado como uma alternativa econômica e ecologicamente eficiente.<span style="mso-font-kerning: 14.0pt;"> Neste tratamento o efluente é aplicado na parte superior de uma rampa vegetada, ficando sujeita ao escoamento superficial, condição que possibilita sua depuração. Este método possui baixos custos e ainda permite que seu efluente seja usado na irrigação de culturas agrícola. No entanto, apesar de seu grande potencial e vantagens, tem sido pouco utilizado, possivelmente devido à carência de informações técnico-científicas acerca do assunto. O objetivo do presente trabalho foi servir como consulta bibliográfica e fornecer informações que contribuam com a difusão e adequação de tal tecnologia, buscando contribuir com o tratamento de esgotos gerados em pequenos grupamentos humanos, tanto na área rural como na urbana.</span></span><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves />
