| Résumé: | Biological denitrification of drinking water was studiedin
up-flow laboratory reactors packed with alfa stems served as the sole
carbon source as well as the only physical support for the
microorganisms. The highest rates of denitrification were observed in
fresh reactors during their first week of operation and the efficiency of
the process declined therafter. In the first part, we have analysed the
influence ohhydrolyc and volumic load to value the capacity of nitrate
prurification in a down flow submerged biofilter then with an
experimental design approach, we have analysed the qualitative and
quantita-tive aspects of the effects of some factors, concentration of
nitrate (80-200 mgl-1 and velocity (0.31 mh-1 on different responses like
the apparentrate of denitrification as well as concentration of nitrite,
nitrate and chemical demand on oxygen (DCO)in the reactor outlet. |
