"charbon actif" : Charbon végétal auquel un traitement a donné une surface spécifique considérable, utilisé pour l’adsorption des matières communiquant à l’eau un goût, une odeur ou une couleur; il est employé aussi pour adsorber l’excès de chlore dans les eaux désinfectées. Le produit commercial est soit granulaire, soit pulvérulent. 6, record 1, French, - charbon%20actif%20en%20poudre

Part of the pollution can be removed by the use of powdered activated carbon, though without a marked reduction being achieved. This method of treatment will be used to iron out the pollution peaks.

It is not recommended that powdered activated carbon should be used by pouring it into water which will then merely be filtered through sand; it is quite possible that the finer particles of the activated carbon would pass through the sand. Powdered activated carbon may nevertheless be introduced upstream of the sand filter, provided that a cellulose of diatomaceous earth pre-coat filter is installed downstream to ensure retention of the fine particles of carbon. 1, record 4, English, - cellulose%20pre%2Dcoat%20filter

Il est déconseillé d’utiliser le charbon actif en poudre par déversement dans une eau qui sera ensuite simplement filtrée sur sable : il y a en effet risque de passage des particules les plus fines du charbon actif à travers le matériau. On peut cependant envisager l'introduction du charbon actif en poudre avant le filtre à sable, à condition de prévoir à l'aval un filtre à précouche de cellulose ou de diatomées permettant la rétention des fines de charbon. 1, record 4, French, - filtre%20%C3%A0%20pr%C3%A9couche%20de%20cellulose
