Granulats pour filtration air<\/h2>\n

\t\u2022<\/span> Si les installations de biofiltre purificateur d’air utilisent g\u00e9n\u00e9ralement un garnissage organique, l\u2019utilisation de m\u00e9dia min\u00e9raux tend \u00e0 se d\u00e9velopper compte tenu de leur durabilit\u00e9 et des cons\u00e9quences bien compr\u00e9hensibles sur l\u2019entretien de l\u2019installation.<\/p>\n

\t\u2022<\/span> Majoritairement utilis\u00e9s pour la suppression des odeurs par r\u00e9duction des H2S, le Granulex\u00ae<\/span> est disponible dans plusieurs granulom\u00e9tries adapt\u00e9es aux besoins des industriels de la filtration.<\/p>\n

\t\u2022<\/span> Structure vitrifi\u00e9e r\u00e9sistante aux attaques acides et basiques, l\u2019ardoise expans\u00e9e ne s\u2019alt\u00e8re pas quelque soit la nature des produits filtr\u00e9s. Cette r\u00e9sistance assure des co\u00fbts d\u2019entretien extr\u00eamement bas pour vos solutions de filtration.<\/p>\n

\t\u2022<\/span> Les granulats pour m\u00e9dia filtrant GranuFiltre sont livrables conditionn\u00e9s en big bag de 1,5 m3, en camion benne vrac (40\/42 m3) et en camion citerne \u00e0 vidange pneumatique (25 m3). La livraison par camion citerne \u00e0 vidange pneumatique permet une mise en place rapide du m\u00e9dia filtrant mais d\u00e9t\u00e9riore les crit\u00e8res d\u2019hydraulicit\u00e9. Le CU augmente de 0,15 et le D10 diminue de 3 \u00e0 7 % selon la longueur et le parcours des tuyaux de vidange qui d\u00e9terminent la pression d\u2019air de transport habituellement comprise entre 0,7 et 2 bars.<\/p>\n

Ce granulat ne contient pas de substances class\u00e9es dans SVHC.<\/p>\n<\/div>\n
