    Elimination de laTyrosine par Adsorption sur Différents Matériaux et Effet de la Minéralisation des Eaux
    (University of Eloued جامعة الوادي, 2013-11-05) Bouchemal, Fattoum; Achour, Samira
    The objective of this work is to study the possibilities of tyrosin retention onto various adsorbents (granular activated carbon and powdered activated carbon, activated bentonite, activated alumina,). The literature review has presented the main characteristics of natural organic matter and more particularly amino acids of which tyrosin. The most current techniques of depollution were described while insisting on the process of adsorption on various materials. During the experimental study, the tests carried out on static system to follow the tyrosin kinetics adsorption on various materials tested on distilled water or mineralized waters. kinetics led to various removal efficiencies of tyrosin . The influence of reactional parameters such as the mass of adsorbent, for a constant mass of adsorbent, The The best results were obtained for activated carbon. Removal is improved when the medium of dilution is mineralized. An increase in removal is also noted when the masses of adsorbents increase, depending however on the limitations of these.

    Performance of a wastewater treatment plant in south-eastern Algeria
    (جامعة الوادي - university of el oued, 2020-11-07) Khechekhouche, Abderrahmane; Bouchemal, Fattoum; Kaddour, Zineb; Salim, Khechana; Miloudi, Abdelmonem
    The experimental study was carried out on an urban wastewater purification station located in the region of El Oued -Kounine- in south-eastern Algeria. During 6 months, samples were taken every month to study the Physico-chemical parameters of this station. Monthly monitoring of SS, COD, BOD5 was made from September 2017 to February 2018 and the results obtained show that the average elimination rates were 77.76, 74.10 and 80% respectively for BOD5, DCO and SS. The average of the ratio COD/BOD5 during the 6 months of follow-up is equal to 2.9.
