Coagulation-floculation au sulfate d’aluminium de composés organiques phénoliques et effet de sels de calcium et de magnésium

Abstract: L’objectif de la présente étude est d’observer l’efficacité de la coagulation-floculation par le sulfate d’aluminium sur l’élimination des composés organiques à fonctions phénoliques (phénol et pyrogallol). L’intérêt s’est porté plus particulièrement sur l’incidence de sels minéraux constitutifs de la dureté « calcium et magnésium » et souvent présents dans la matrice minérale des eaux algériennes. Des essais de Jar-Test ont été réalisés sur les deux composés phénoliques dissous dans l’eau distillée … Show more

“…In addition, many researchers report that the efficiency of coagulation process to remove organic matter and phenolic compounds from OMW, depends mainly to coagulant's type and dosage, pH, mixing condition and temperature on the one hand and phenolic compounds properties including particle size, charge and hydrophobicity (Korshin et al, 2009;Iakovides et al, 2014) and the presence of anionic (PO 4 3-, SO 4 3-, Cl -) and cationic (Ca 2+ , Mg 2+ , Na 2+ ) minerals (Lin and Lee, 2013;Hecini and Achour, 2014), on the other hand.…”

“…This result is in accordance with the works of Rezeg and Achour (2005) who found that the application of aluminum sulphate allowed an important removal of gallic acid (72.58%) and pyrogallol (53.58%) compared with phloroglucinol (10%) (functions acid non-adjacent). Hecini and Achour (2014) also indicated that the efficiency of the coagulation using aluminum sulphate on the removal of organic compounds with phenolic functions (pyrogallo and phloroglucinol) depends on the number and position of phenolic groups on the molecules. The removal of some phenolic compounds (benzoic acid, phenol, naphtol, salicylique acid, etc.)…”

“…Physical or chemical processes have been widely used to remove pollutants from wastewater. These methods include: coagulation-flocculation [1], biological treatments (biodegradable pollutants) [2], electrochemical methods [3] [4], membrane processes [5], adsorption [6] [7]. The use of activated carbon in the adsorption process is in great demand.…”
