Granulats pour lit bact\u00e9rien<\/h2>\n

\u2022<\/span> L\u2019utilisation des ardoises expans\u00e9s pour la phyto\u00e9puration est un proc\u00e9d\u00e9 fortement utilis\u00e9 outre-atlantique. En effet, la forte surface sp\u00e9cifique du Granulex\u00ae<\/span> lui permet d\u2019augmenter significativement le temps de percolation.<\/p>\n

\u2022<\/span> Le volume poreux, deux fois sup\u00e9rieur aux pouzzolanes utilis\u00e9es traditionnellement comme support min\u00e9ral lui permet de fixer plus efficacement la masse active des micro-organismes et donc d\u2019augmenter sensiblement le rendement de filtration.<\/p>\n

\u2022<\/span> De nombreuses stations d\u2019\u00e9purations par macrophytes sont en fonctionnement depuis dizaines d\u2019ann\u00e9es avec comme m\u00e9dia filtrant du sable de Granulex\u00ae<\/span>.<\/p>\n

\u2022<\/span> Les performances m\u00e9caniques sont \u00e9galement un atout pour l\u2019utilisation des sables de Granulex\u00ae<\/span> dans un lagunage ou un filtre plant\u00e9. De surcro\u00eet, sa structure vitrifi\u00e9e et son absence de CaO assure une dur\u00e9e illimit\u00e9e de votre filtre.<\/p>\n

\u2022<\/span> Disponibles dans toutes les granulom\u00e9tries courantes, le Granulex\u00ae<\/span> s\u2019adaptera a vos besoins de filtration en optimisant vos process, tant dans leur rendement que dans la fiabilit\u00e9 de ceux-ci.<\/p>\n

\u2022<\/span> Les granulats pour m\u00e9dia filtrant sont livrables conditionn\u00e9s en big bag de 1.5 m3, en camion benne vrac (23 \/ 25 m3).\n<\/div>\n
