    The degradation of methylene blue by bacterial strains isolated from the peel of Red Beet
    (Université M'Hamed Bougara Boumerdes, 2018) Abai, N.; Abed, F.; Babakhouya, N.; Benrachdi, K.
    The textile industry generates half of the industrial pollution flows, these effluents can be very colorful and difficult to treat. The treatment of these effluents has become a priority in the world, the development of methods and the optimization of existing processes, are the subject of a large number of works. In the present work the methylene blue was degraded by two bacterial strains BP1 and BP2 isolated from the peel of red beet, identified as Acinetobacter Johnson II BP1 and BP2 as Bacillus weihenstephanensis. The effect of the initial concentration, pH, temperature, and addition of the carbon source and nitrogen source on the biodegradation of the dye was determined.

    Etude du potentiel d’utilisation des déchets agroalimentaires, les grignons d’olives et les noyaux de date pour récupération et adsorption des métaux lourds
    (Université M'Hamed Bougara Boumerdes, 2015) Babakhouya, N.; Boughrara, S.; Abed, F.; Abai, N.; Midoune, S.
    La présente étude porte sur l’application d’un adsorbant naturel ‎préparé à base de grignon d’olives et de noyaux de dattes à ‎différents pourcentages dans le domaine de traitement des ‎effluents liquides industriels. Dans notre travail nous nous ‎sommes intéressés à son application pour le cadmium (métal ‎lourd). L’effet de plusieurs paramètres tel que le temps de contact, ‎la concentration initiale en ions de cadmium, et le pH de la ‎solution a été étudié en système en batch. Une modélisation des ‎isothermes d’adsorption a été effectuée à l’aide des models ‎d’isothermes de Langmuir, Freundlich et Temkin et leur ‎coefficient de corrélation obtenus, indiquent que le model de ‎Langmuir est favorable pour la plupart des proportions ‎d’adsorbants

    Modeling of adsorption isotherms of methylene blue by olive ‎stones
    (Aljest, 2015) Abed, F.; Babakhouya, N.; Boughrara, S.
    The present study focuses on the recovery of the waste food « the ‎olive stones » in the field of industrial liquid effluent treatment. The ‎material is used in its native form. In order to test the ‎performances of the adsorbent we were interested in cationic dye ‎the methylene blue considered as pollutant. The effects of several ‎parameters such as contact times, initial concentration of dye, ‎solution and pH were studied in batch system.‎ Modeling of experimental results was performed using models of ‎Langmuir and Freundlich isotherms, which show that adsorption ‎follows the Langmuir model with high correlation coefficients

    Study of the adsorption of methylene blue by natural materials (olive stone, date pit and their mixture) in fixed bed column
    (ALJEST, 2019) Abed, Fatma; Aksa, H.; Abai, N.; Babakhouya, N.
    The present study focuses on the recovery of two agro-food waste available in our country with significant quantities olive pomace and date pits for the removal of a synthetic dye which is methylene blue. Both materials were used in their native forms separated and mixed to improve their adsorptive capacity. A range of physico-chemical analysis was performed to characterize adsorbents used, among them: the FTIR spectroscopy and the scanning electron microscopy. The ability of adsorbents prepared to adsorbe methylene blue (MB) from the aqueous solution was investigated in a fixed bed column. The effects of several important parameters were studied, such as initial concentration of MB, flow rate and bed height. The corresponding breakthrough curves were calculated.
