| Résumé: | Surfactants are major components of detergents and
cosmetics; they are among the most undesirable pollutants in the
environment because of their toxic effects on aquatic organisms.
The main objective of this work is to define the elimination limits of
the three different types of surfactants (anionic, cationic and
amphoteric) by activated sludge.
The results obtained were modeled by the model ASM1 (Activated
Sludge Model N°1) in order to establish a better representation of the
kinetic parameters such as the rate of disappearance of surfactant rs
and the growth rate of the biomass rc. According to the classification
based on biodegradation surfactants, the results obtained suggest
that the AES is more degraded than the other surfactants with rs AES =
17.01 mg / lh at (cAES = 40 mg / l, T = 35 ° C) and rc AES = 1.42. mg /
lh under the same conditions. |
