CONT

The pH of the dechlorinated water falls during [the] reaction. This dechlorination action is characterized by the half-dechlorination depth, that is, the depth of the filter bed which, for a given speed, causes the reduction by one half of the amount of chlorine in the water. The pH has considerable influence on this depth.

CONT

Le pH de l'eau déchlorée s'abaisse au cours de la réaction. On caractérise cette action déchlorante par la longueur de demidéchloration: c'est la hauteur de lit filtrant qui, à une vitesse donnée provoque une diminution de moitié de la dose de chlore dans l'eau. Le pH a une grande influence sur cette longueur.
