| Résumé: | The objective of this study is to valorize an urban waste,
the sludges from the wastewater treatment plant of
Boumerdes/Algeria for the removal of methylene blue dye in
aqueous solution by adsorption. The material made from this sludge
has been characterized by various techniques: X-ray fluorescence
microscopy (XRF), X- ray diffraction (XRD), Fourier transform
infrared spectroscopy (FTIR) and scanning electron microscope
(SEM) to obtain information concerning their structures and their
compositions.A systematic study of various parameters such as: effect
of adsorbent dosage, contact time and initial dye concentration was
carried out in order to optimize the ideal conditions for a good
adsorption of the studied pollutant; especially the kinetics of
adsorption.The exploitation of experimental results using different
kinetic models and adsorption isotherms showed that the sludge has
similar adsorption characteristics to those of activated carbon, which
perfectly confirms the applicability of the activated sludge in the
wastewater treatment. |
