Traitement de lixiviats stabilisés de décharge par des membranes de nanofiltration

Abstract: Le terme "lixiviat" ou "jus de décharge", désigne l'eau qui a percolé à travers les déchets en se chargeant de polluants. Ces effluents pollués doivent être traités.En raison des exigences croissantes des normes de rejet et de la stabilisation des lixiviats au cours du temps, de nouvelles techniques ont fait leur apparition dans ce domaine. La technologie de l'osmose inverse s'est développée dans de nombreux pays européens. Cependant cette technique sélective et coûteuse, se justifie seulement quand les normes… Show more

“…The high rejection rate for sulfate ions and for dissolved organic matter (Table 20) together with very low rejection for chloride and sodium reduces the volume of concentrate [159]. Few studies mention the use of NF to treat landfill leachates [5,38,73,[162][163][164]. Nearly 60-70% COD and 50% ammonia were removed by NF, whatever membrane material and geometry (flat, tubular, or spiral wounded), with an average velocity of 3 m s −1 and a transmembrane pressure between 6 and 30 bar.…”

“…The leachates as polluted effluents should be treated/managed to avoid negative environmental and/or sanitary impacts and meet the increasing requirements of discharged standards [11]. The Upflow Anaerobic Sludge Blanket (UASB) treatment technique has been used for anaerobic treatment of influents in many countries [12] generally at a temperature close to 20°C or beyond.…”

“…• Le choix du modèle de notre réacteur de UASB a donné satisfaction pour le traitement d'une quantité de 1/10 de la quantité produite journalièrement ce qui va nous donner une idée sur le dimensionnement de notre réacteur UASB pour le traitement de ces effluents a forte charge organique (Trebouet et al, 1998 ;Khattabi et al, 2002) et avoir un écoulement de traitement permanant.…”
