... the most common method for primary [wastewater] treatment is the primary sedimentation tank (also called the primary settling basin) ... It is a vessel in which solids settle out of water by gravity. The settleable solids are pumped away (as sludge), while oils float to the top and are skimmed off. 7, record 1, English, - primary%20settling%20tank

L'épaississement par gravité se déroule dans un décanteur dont le design est assez proche d’un bassin de sédimentation conventionnel : un bassin circulaire où la boue va sédimenter et se compacter. Les boues épaissies sont récupérées par le fond conique, tandis que le surnageant est envoyé selon la solution choisie vers le bassin de sédimentation primaire, le début du procédé de traitement total des effluents, ou vers une autre utilisation. 3, record 1, French, - d%C3%A9canteur%20primaire

The completion of digestion in a secondary digester is only an accessory process. Digestion takes place essentially in the primary digester. This is why some secondary digesters can be equipped with a sold-water injection system to inhibit the effects of the methane fermentation process, to wash the colloidal matter out of the sludge and to promote thickening. 1, record 2, English, - primary%20digester

La finition du processus de digestion dans un digesteur secondaire n’ est qu'accessoire. La digestion se fait essentiellement dans le digesteur primaire. C'est pourquoi les digesteurs secondaires peuvent, dans certains cas, être équipés de dispositif d’injection d’eau froide, cela afin de bloquer les séquelles du processus de fermentation méthanique, de laver les boues de leurs matières colloïdales et de faciliter leur épaississement. 1, record 2, French, - digesteur%20primaire

The completion of digestion in a secondary digester is only an accessory process. Digestion takes place essentially in the primary digester. This is why some secondary digesters can be equipped with a cold-water injection system to inhibit the effects of the methane fermentation process, to wash the colloidal matter out of the sludge and to promote thickening. 1, record 3, English, - secondary%20digester

During primary thickening, some of the water is removed from primary sludge, thereby reducing its volume. As the velocity of the flow slows, gravity causes sludge to settle to the bottom of the thickener where it is raked into a hopper and pumped to mixing tanks where it is combined with sludge from the secondary system. 1, record 4, English, - primary%20thickening
