The BIOLIFTTM process uses the technique of fixed bacteria on a fluidized bed. The purifying biomass is caught on grains of sand which are maintained in fluidization by an upward air flow. The reactor is situated downstream of an activated sludge tank and ensures nitrification of the effluent. At its outlet a recirculation loop channels some of the mixed liquor back to the activated sludge tank-head where the nitrates are broken down into gaseous nitrogen(denitrification). The remaining mixed liquor is channelled towards the clarification stage where the purified water is separated from the sludge. 2, record 1, English, - fixed%20bacterium

[...] OTV met en œuvre des réacteurs biologiques à bactéries fixées dans un grand nombre de ses stations d'épuration. Après BIOCARBONE et BIOSTYR, un réacteur biologique «nouvelle génération» appelé BIOLIFT, vient d'être mis au point pour la nitrification des eaux usées. BIOLIFT utilise la technique des bactéries fixées sur un lit fluidisé. Les bactéries nitrifiantes sont fixées sur un matériau particulaire dense, tel que du sable. La circulation de l'eau, générée par une colonne d'air lift, maintient le matériau en suspension. 3, record 1, French, - bact%C3%A9rie%20fix%C3%A9e

[...] stade [...] employé, habituellement dans les séquences SC, pour délignifier les pâtes jusqu'à de très faibles indices kappa. Le mélange de la pâte et du gaz est un facteur important parce que la vitesse de réaction de l'ozone est très élevée et sa concentration dans l'oxygène relativement faible. L'ozonation est effectuée normalement à une température de 50-60 °C, à un pH entre 2 et 4 et un temps de résidence de quelques minutes. L'ozone peut également être associée au bioxyde de chlore dans un stade combiné (DZ). 1, record 2, French, - stade%20%C3%A0%20l%27ozone

Optical devices, which, by measuring the colour changes in pulp as delignification progresses, can continuously monitor the degree of bleaching or brightness of a pulp slurry at different stages along the bleaching operation so that the flow of bleaching agent required in a bleaching stage can be controlled either manually or electronically. The optical information obtained can be used to control flows upstream from the measuring point, which is called a "feedback" system, or the information can be used to control flows downstream from the measuring point, which is called a "feed forward" system. 1, record 3, English, - optical%20sensor
