Les appareils de filtration d\u2019eau en ext\u00e9rieur
\n<\/strong><\/h4>\n

Une filtration qui serait sup\u00e9rieure \u00e0 1\u00b5m (1\u00b5m =0.001mm = 1000 nanom\u00e8tres ) pour une eau de boisson ne pourrait pas \u00eatre consid\u00e9r\u00e9e comme s\u00fbre d’un point de vue sanitaire (voir le tableau ci-dessous).<\/p>\n

Le syst\u00e8me de filtration par cartouche c\u00e9ramique est tr\u00e8s utilis\u00e9. En effet, les cartouches ne sont pas tr\u00e8s ch\u00e8res et certaines ont une dur\u00e9e d’utilisation longue selon certains fabricants. Le principe de filtration par c\u00e9ramique permet de filtrer \u00e0 environ 0.2 \u00b5m (200 nanom\u00e8tres). Cela bloque certains \u00ab ind\u00e9sirables \u00bb comme les bact\u00e9ries. Mais ces filtres ne sont pas suffisant si des virus \u00e9taient pr\u00e9sents dans l’eau. Un autre inconv\u00e9nient sur le filtre \u00e0 c\u00e9ramique : il est fragile -comme toute c\u00e9ramique – et si il venait \u00e0 se fissurer suite \u00e0 un choc lors de son transport, cela remettrait en cause la qualit\u00e9 de sa filtration. Une micro-fissure laissera alors passer ce que les micro-pores de la c\u00e9ramique auront bloqu\u00e9. Et ces micro-fissures ne peuvent jamais \u00eatre vues \u00e0 l\u2019\u0153il nu. Ce risque n’est pas \u00e0 n\u00e9gliger.<\/p>\n

Autre nouveau proc\u00e9d\u00e9 de filtration : l’ Ultrafiltration par membranes \u00e0 fibres creuses. Son avantage indiscutable est son niveau de filtration. Ce syst\u00e8me\u00a0 offre une filtration \u00e0 0.01\u00b5m (10 nanom\u00e8tres). Cela procure une tr\u00e8s grande s\u00e9curit\u00e9 sur la qualit\u00e9 finale de l\u2019eau surtout dans des r\u00e9gions o\u00f9 l’eau risque d’\u00eatre contamin\u00e9e.<\/p>\n

La mauvaise qualit\u00e9 de l\u2019eau est malheureusement l\u2019une des causes principales de d\u00e9c\u00e8s des enfants de moins de 5 ans en Afrique et en Asie.<\/p>\n

Conclusion<\/h4>\n

Ne vous fiez pas \u00e0 la limpidit\u00e9 de l\u2019eau<\/strong> pour la consid\u00e9rer comme potable. M\u00eame en montagne, une source peut contenir des bact\u00e9ries ou des virus.<\/p>\n

Filtrer partout son eau, c’est s\u2019assurer de sa potabilit\u00e9, en ext\u00e9rieur et m\u00eame chez soi. En situation d’urgence, par exemple apr\u00e8s des inondations o\u00f9 l’eau peut \u00eatre fortement pollu\u00e9e, avoir un proc\u00e9d\u00e9 de filtration chez soi est int\u00e9ressant. Une s\u00e9curit\u00e9 qui vaut bien quelques gadgets souvent inutiles…<\/p>\n

Dans tous les cas, seule une filtration \u00e0 0.01\u00b5m vous assurera que l’eau que vous buvez ne contient pas d’agents pathog\u00e8nes.Votre sant\u00e9 en d\u00e9pend.<\/p>\n

Avec quel type d’appareil avoir une filtration \u00e0 0.01\u00b5m ? Tr\u00e8s peu de mat\u00e9riels offrent ce niveau d’exigence.<\/p>\n
