biochemical oxygen demand; biological oxygen demand; BOD; B.O.D.: [These terms and abbreviations can also refer] to a chemical procedure for determining this amount. This is not a precise quantitative test, although it is widely used as an indication of the organic quality of water. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a robust surrogate of the degree of organic pollution of water. ... BOD can be used as a gauge of the effectiveness of wastewater treatment plants. ... BOD is similar in function to chemical oxygen demand (COD), in that both measure the amount of organic compounds in water. However, COD is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biologically active organic matter. 2, record 1, English, - biochemical%20oxygen%20demand

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 8, English, - rapid%20infiltration%20process

[...] 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.

Biological Filter. High-rate treatment can also be obtained in a biological filter system. Biological filtration is a technique for promoting contact between a free-flowing wastewater and a stationary growth of microorganisms in the presence of atmospheric air. The system does not depend on filtration in the usual sense for its effect. ... Biological filter systems (such as the trickling filter) have generally proven to be unsuitable for pulp and paper wastewaters, exhibiting even greater instability to waste variability than activated sludge systems. However, the rotary disc system (a more recent design of biological filter) has been successful on a number of wastewaters and appears to deserve consideration for future applications. In this system a biological growth is cultivated on the disc surfaces. A series of closely-spaced corrugated plastic discs are anchored to a rotating shaft and supported above a trough through which the wastewater is channeled at a controlled rate. The lower 30 to 40% of each disc extends into the wastewater, while the upper portion is exposed to air. Thus, an area of biological growth alternates between submergence to absorb food and exposure to air for oxidation. Any number of rotating assemblies can be used in series to achieve the desired degree of BOD removal. 1, record 9, English, - rotary%20disc%20biological%20filter

La filtration biologique consiste à mettre un liquide résiduaire en écoulement naturel au contact d’une population fixe de micro-organismes en présence d’air atmosphérique. Ce procédé ne constitue pas une filtration au sens habituel du terme. [...] Cependant, il s’est avéré que le modèle récent de filtre biologique, à disque rotatif, était efficace pour le traitement de certains effluents, et l'avenir de cet appareil s’annonce donc prometteur. Ce filtre comporte un ensemble de disques rapprochés, en plastique ondulé, assemblés sur un arbre rotatif et installés au-dessus d’une cuve où arrive l'effluent à traiter. La base des disques(environ 30 à 40% de leur surface) plonge dans l'effluent, le haut étant à l'air libre. La zone de croissance biologique est donc alternativement immergée, ce qui lui permet d’absorber des nutriments, puis exposée à l'air pour que l'oxydation se produise. Le nombre d’appareils installés en série dépend de la réduction de DBO souhaitée. 1, record 9, French, - filtre%20biologique%20%C3%A0%20disques%20rotatifs
