In this work, the purified water and waste sludge of Sidi Merouane wastewater treatment plant located in Mila in the Northeast Algeria are characterized in the objective of their valorization in agriculture. The sludge is also used in the production of activated carbon for water water treatment application. The quality of Sidi Merouane treated waters is evaluated through physicochemical analysis. The obtained results show that they are characterized by alkaline pH, high electrical conductivity and low concentrations of nitrate and phosphate. The contents of the analyzed heavy metals are below the limits of water discharges. The mineralogical composition of waste sludge is evaluated by XRD and FTIR analysis. It reveals the presence of clay phases associated with organic matter. Their physicochemical characterization is carried out by measuring pH, electrical conductivity and by analysis of major elements, nutrients, organic matter and metals. The obtained results show the mineral character of the Sidi Merouane waste sludge. Nitrogen is predominantly in organic form; among its mineral species, ammonium predominates whatever the season. Phosphorus is predominantly inorganic and the fraction bound to oxyhydroxids is the most important. The calculated C/N ratio shows that nitrogen is not immobilized.in the waste sludge of the Sidi Merouane wastewater treatment plant. The concentrations of the analyzed heavy metals are below the limits allowed for valorization sludge in agricultural. Activated carbons are prepared from waste sludge of Sidi Merouane plant by calcination at 550 °C and by chemical activation using an acidic mixture (H2SO4 + H3PO4). They are characterized by FTIR and BET analysis and by the determination of pHpzc and iodine number. The effectiveness of the use of the prepared carbons in waste water treatment is evaluated through the adsorption of an organic pollutant (a dye) and an inorganic pollutant (metal ion). A commercial activated carbon is also used for a comparison. The obtained results show that the activated carbon prepared by chemical activation is characterized by a high specific surface area (1114 m2/g), an important iodine number (1435) and an acidic pHpzc (3.6). Its adsorption capacities for Black Eriochrome T and chromium (III) ions are 370mg/g and 32mg/g respectively. These capacities are higher than those of the commercial activated carbon used.

Another study has been led on the degradation of Monocloramine in homogeneous phase via direct UV photolysis, H2O2/UV and
NaOCl/UV. Treated separately, both dyes have shown an appreciable adsorption on the two supports and that this process is well represented by an apparent kinetic of order 2.
Besides, Congo Red and Ethyl Violet are described by isotherms of type L and S respectively and that process is also well represented by the model of Langmuir for Ethyl Violet and Redlish-Peterson of Congo Red. On the other hand, the photocatalytic system led via TiO2/UV has been efficient toward both dyes and this process follows an apparent
rate constant of order 1. In another part, this process is well described by the kinetic model of Langmuir-Hinshelwood and that oxidation process occurs, mainly, in surface. The inhibition process has been demonstrated by alcohols proving thereby that radicals •OH are the main oxidation route. The photoproducts issued from the decolorization of the two dyes have been identified using masse spectroscopy technic. This has permitted to establish a mechanism of degradation for the two dyes. Same efficiency is obtained using CAZnO/UV process (CA: activated carbon issued from olive cakes). In another side and in the mixture, the treatment of the two dyes by both systems has, shown that the efficiency decreases as the concentration of the other added dye increases. Indeed, the addition of the second substrate slows down the disappearance speed of the other. The kinitics model
remained unchanged for the two processes (2nd order for adsorption and 1 st order for photocatalysis) The last part treats the degradation of the Monochloramine which occurs via direct UV photolysis in presence of two lamps:
BP (254 nm) and MP (200-600 nm).
The obtained results have been significant. Furthermore, these results have been greatly enhanced mainly by H2O2/UV. However, for NaOCl/UV system we could mention that the disappearance rate slows down because of the formation of photoproducts such as: Mono, Di and Trichloramines. Moreover, the process is well described by an apparent kinetic of order 1 and those photoproducts identified in H2O2/UV, NaOCl/UV and direct photolysis systems are nitrates and nitritesDiplôme : Doctorat en sciences En ligne : ../theses/chimie/ALA6959.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10358 Elimination des polluants organiques par méthodes physicochimiques et photochimiques en milieux aqueux. : Cas de l’éthyle violet et du rouge congo (séparés et mélangés) et de la monochloramine [texte imprimé] / Abdessemed Ala, Auteur ; Kamel Djebbar, Auteur . - جامعة الإخوة منتوري قسنطينة, 2016 . - 224 f. ; 30 cm.
