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

El objetivo que persigue la aireación graduada es acomodar la cantidad de aire suministrada a la demanda de los microorganismos, conforme el líquido atraviesa el tanque de aireación. Este proceso se aplica cuando las aguas receptoras requieren que se efectúe un mayor grado de tratamiento que el que se logra mediante el tratamiento primario, pero inferior al grado que se obtiene generalmente por el método convencional de lodos activados. 1, record 2, Spanish, - aireaci%C3%B3n%20graduada
