“…Steel slag has been found to be rich in iron and calcium oxides, promoting P removal. According to the research results of Drizo et al [15], steel slag demonstrated nearly 100% P removal efficiency as substrate of CW over a period of 180 days. Cost is another important requirement in substrate selection in CW.…”

“…Their research results proved that the baffled CW was better than conventional unbaffled CW in treatment of N removal. Use of a steel slag filter of electric arc furnace following CW has been shown to significantly increase P removal [15]. In this study, we applied a two-stage VFCW containing steel slag media to remove N and P in secondary effluent from a municipal sewage treatment plant.…”

“…By comparing most of industrial by products, steel slag is a low-cost and abundant material, which its combination with small secondary treatment systems (such as constructed wetlands) is preferred in compared to the others methods [9,10]. The slag contains various metal oxides such as iron oxides and alumina that may be effective in P reduction from domestic, agricultural effluents and municipal [11].…”

Abstract. Significant quantities of steel slag are generated as waste material or byproduct every day from steel industries. Slag is produced from different types of furnaces with different operating conditions. Slag contains Ferrous Oxide, Calcium Oxide, Silica etc. Physical and chemical properties of slag are affected by different methods of slag solidification such as air cooled, steam, and injection of additives. Several material characterization methods, such as X-ray Diffraction (XRD), Scanned Electron Microscopy (SEM) and Inductive Coupled Plasma (ICP-OES) are used to determine elemental composition in the steel slag. Therefore, slags can become one of the promising materials in various applications such as in transportation industry, construction, cement production, waste water and water treatment. The various applications of steel slag indicate that it can be reused and utilized rather than being disposed to the landfill. This paper presents a review of its applications and utilization

“…The maximum P adsorption capacity of a filter medium generally increases as the filter medium size decreases [10,11]. The P removal due to sorption decreases over time because of finite P sorption by the bed [4,[12][13][14], which is referred to as the 'ageing phenomenon' in wetlands that receive wastewater [15]. Richardson [16] observed that in HSFCWs saturated with P, leaching of P from the substrate occurred.…”

“…Richardson [16] observed that in HSFCWs saturated with P, leaching of P from the substrate occurred. Adsorption and precipitation of P by the substrate are finite processes and once the material is saturated, it has to be rejuvenated, or more probably replaced [14].…”

Abstract:A horizontal subsurface flow constructed wetland was investigated after eight years of residential wastewater discharge (150 person equivalents). Twenty core samples distributed over the entire wetland were taken from the soil matrix. The distribution pattern of phosphorus (P) accumulation in the substrate of the wetland was determined using kriging technique and P sorption was related to the content of aluminum (Al), calcium (Ca) and iron (Fe). The correlations found between Al, Ca and Fe content and P accumulation in the bed substrate were weak: R 2 = 0.09, R 2 = 0.21 and R 2 = 0.28, respectively. Great heterogeneity was observed in the distribution of Ca, P and organic matter in the superficial and deeper layers of the bed. Hydraulic problems associated with wastewater discharge and conductivity of the bed substrate were suggested to have negative effects on the wetland performance.
