Color removal. The brown color of pulp mill effluents originates with the wood handling, chemical pulping and bleaching operations, and is due to the presence of tannin and lignin derivatives.... Coagulation processes are now preferentially applied to wastewaters following secondary treatment because of more complete color removal. It has also been found that the biological process itself causes the formation of additional color. The rapid infiltration process appears to be a good choice for color removal at mill sites with suitable topography and subsoil characteristics. In this method, the wastewater is percolated through porous subsoil strata before reaching the receiving water. The color is removed by adsorption and precipitation onto soil particles. Because the soil strata becomes rather rapidly saturated, it is necessary to operate a number of basins intermittently, allowing time between dosages for regeneration of the adsorbing surfaces. 1, record 3, English, - rapid%20infiltration%20process

Suppression de la couleur. La couleur marron des effluents des usines de pâtes et papiers provient des opérations de manutention du bois, de la mise en pâte par un procédé chimique et du blanchiment; elle est due à la présence de tannins et de dérivés de la lignine. [...] L'infiltration rapide est une technique apparemment très prometteuse utilisée pour supprimer la couleur quand la topographie et les caractéristiques du sous-sol le permettent : l'effluent percole à travers les strates poreuses du sous-sol avant d'arriver au niveau des eaux réceptrices, et les produits colorés sont éliminés par adsorption et précipitation sur les particules du sol. Comme le sol se sature rapidement, il faut utiliser plusieurs bassins en alternance afin de disposer d'un temps suffisant pour régénérer les surfaces adsorbantes. La régénération du terrain se produit par oxydation biologique naturelle. 1, record 3, French, - infiltration%20rapide

Color removal. The brown color of pulp mill effluents originates with the wood handling, chemical pulping and bleaching operations, and is due to the presence of tannin and lignin derivatives. These compounds are slow to biodegrade and are usually little affected by conventional secondary treatment methods. Changes in plant design(e. g., elimination of wet debarking, bleach process modifications) have been successful in lowering effluent color, but the problem remains serious in situations where the dilution factor in the receiving water is low. 1, record 4, English, - color%20removal

Suppression de la couleur. La couleur marron des effluents des usines de pâtes et papiers provient des opérations de manutention du bois, de la mise en pâte par un procédé chimique et du blanchiment; elle est due à la présence de tannins et de dérivés de la lignine. Ces composés mettent longtemps à se dégrader par voie biologique et ils sont peu sensibles aux méthodes classiques de traitement secondaire. Bien que l'on ait réussi dans certaines usines à produire des effluents moins colorés (par exemple en modifiant le procédé de blanchiment), le problème reste entier dans les endroits où le facteur de dilution par les eaux réceptrices est faible. 1, record 4, French, - suppression%20de%20la%20couleur
