Traitement des eaux de consommation par filtration lente sur sable à plusieurs étapes

Abstract: La possibilité d’éliminer la turbidité et les coliformes, en utilisant un système de filtration lente sur sable à plusieurs étapes, a été étudiée à l’échelle du laboratoire. Le but de l’étude était de montrer que cette technologie constitue une solution de traitement efficace de l’eau en milieu rural et dans de petites agglomérations des pays en voie de développement. Dans cette étude, un système a été monté et testé. Ce système était constitué de deux filtres lents à sable en série, lesquels sont précédés de … Show more

“…In Morocco, landfilling is currently the most common way to dispose of solid waste. The percolation of landfill leachate into the environment causing disease and other environmental hazards to both aquatic life and humans is alarming (Disa-Disa & al., 2020) [1]. Landfill leachate is generated as a result of precipitation, surface runoff, and seepage or water contained waste (Kossitse, D. & al., 2019) [2].…”

“…Sendo assim, com possibilidade para alternativas de pré-tratamento, a FiME apresentase com potencial a superar as limitações da FL (VERAS; DI , de forma que seja possível promover a redução de parâmetros físico e químicos, como cor, turbidez e sólidos grosseiros (DISA-DISA et al, 2014;SILVEIRA;COUTINHO, 2016), além da remoção de microrganismos (MENDONZA et al, 2019), substâncias húmicas (TANGERINO; DI BERNARDO, 2005) e algas presentes na água bruta ( TANGERINO et al, 2001;TANGERINO et al, 2013). Para tanto, a técnica de FiME pode ainda incorporar materiais de diversas origens para compor o meio filtrante de suas etapas de filtração, a exemplo de materiais não convencionais e resíduos agroindustriais, como as fibras de coco, resíduos cerâmicos e maravalha (NUNES; LIMA; MICHELAN, 2018;SANTOS JUNIOR et al, 2020).…”

“…The second ones are those with lower diameters passing through the membrane. These membranes are usually made up of ceramic materials for decades, processes with membrane are used in the treatment of drinking water [6]. This technique uses a gradient of pressure to make pass water through the pores of the membranes [7].…”
