Cr), Cu, Total Fe (Tot. Fe), Mn, Ni, Pb, Sb, Sn, and Zn from urban effluent by wastewater treatment plants (WWTPs) operated under five-stage Bardenpho (R) process were investigated and water soluble metals in the dewatered sludge were quantified. Samples were collected from two WWTPs on a weekly basis over an approximately 2.5-year time span. Tot. Fe and Al were the most abundant, As, Pb, Ni, Cu, and Cd were the least abundant metals in the influents of both WWTPs. Removal efficiencies above 75% were achieved for Tot. Cr, Tot. Fe, Al, and Cu, whereas, no significant removal was observed for As, Cd, Pb, Sb, and Sn. Removal of Tot. Cr, Cu, Tot. Fe, Zn, Al, Mn, and Ni were influenced by influent suspended solids concentrations, and of Tot. Cr, Zn, and Cd were influenced by their initial content in the influent. Zn removal efficiency of biological nutrient removal (BNR) system in this study was higher and Cd removal efficiency was lower than that of conventional activated sludge reported in the literature. No remarkable difference for metals such as Cu, Mn, Ni, and Pb was observed between the removal efficiencies of conventional system and BNR system.eninfo:eu-repo/semantics/closedAccessScience & technology - other topicsEnvironmental sciences & ecologyMarine & freshwater biologyWater resourcesBardenpho (R)RemovalSourcesSuspended solidsSewage-treatment worksHeavy-metalsActivated-sludgeSpeciationBiosorptionCadmiumBalanceNickelFateLeadBursa [Turkey]TurkeyAluminumArsenicCadmiumCopperEffluentIronLeadNickelPollutant removalPollutant sourceSludgeUrban areaWaste treatmentWastewaterArticle0003138800000102-s2.0-84872683420153165412Green & sustainable science & technologyEnvironmental sciencesMarine & freshwater biologyWater resourcesActivated Sludge; Heavy Metal; Batch Reactors
