Abstract

L'invention vise à éliminer, pour de l'eau potable pour des êtres humains ainsi que du bétail et de la volaille, le problème de substances dangereuses lorsqu'elles sont ingérées, telles que du chlore résiduel, et à produire des propriétés anti-microbiennes contre des bactéries communes, tout en rajoutant également des composants minéraux. A cet effet, l'invention porte sur un agent de purification d'eau, qui agit sur de l'eau brute de façon à la raffiner en une eau qui convient mieux à la boisson. Celui-ci est obtenu par le mélange de différents composants : en % en masse, 35 à 45 % de charbon actif, 30 à 40 % de zéolite et 20 à 30 % de sable corallien calciné. Le mélange des différents composants prend la forme d'une poudre, et est mis en œuvre par remplissage dans un récipient formé à l'aide d'un matériau perméable à l'eau ayant une maille de tamis inférieure à sa taille de particules.
