“…Fe extraction using ammonium oxalate from solution was also found to be a good indicator of P adsorption via ionic Fe [31]. Thus, more dissolved Fe would result in more P precipitation and is related to higher total amounts of Fe in the substrates [32]. Furnace slag also resulted in a higher P sorption capacity than ceramic (Table 3) because of the higher Fe content (Table 1).…”

CWs have been designed and constructed to use natural processes for the removal of pollutants from contaminated water in a more controlled environment [1][2][3]. Previous results have shown that substrate adsorption plays the most important role in P immobilization [4][5][6][7][8]. Therefore, cheap and effective P adsorbents are highly desirable [9][10][11].The most commonly used substrates in CWs are quartz sands [12], activated carbon (AC) [12][13], zeolite [14], ceramic [15], and furnace slag [16][17], and prior research has shown that the removal of P by these substrates mainly occurs though physical adsorption, chemical precipitation, and ion exchange [10][11]. However, P sorption properties of the substrates have not been systematically estimated, which resulted in many defective packing layer designs for CWs [3,11]. Thus, it is important to evaluate the P adsorption properties of the substrates before full-scale use was performed.Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractTo provide a selection criteria to choose substrates according to the quality of the water requiring treatment in constructed wetlands (CWs), phosphorus (P) adsorption properties of four quartz sands with different physicochemical characteristics and four substrates commonly used in CWs were tested and evaluated via both the Langmuir and Freundlich equations. The effects of organic maters (OM) on P adsorption capacities of the substrates were also studied to evaluate the practical values of the substrates. The Langmuir sorption isotherm was used to estimate the P adsorption capacities of the tested substrates in CWs. Overall, the maximum P adsorption for all of the tested substrates decreased as follows: furnace slag > ceramic > zeolite > activated carbon > quartz quartz sands. The P adsorption capacities were significantly influenced by grain size; specific surface area; Fe, Al, Mg, and Ca contents in the substrates; and the amount of added OM. The chemical precipitation of P by the substrates containing Fe was more effective than those containing Ca at the same level. Added OM impacts P sorption by influencing pH, and substrates containing higher Fe and Al concentrations and lower Ca concentrations were more resistant to decreases in the P adsorption capacities due to OM accumulation. Finally, a principle for selecting substrates for the treatment of wastewater with different characteristics was determined.

“…3,4 Therefore, methods for reducing the concentration of phosphorus in contaminated water have become a hot topic in environmental science. 5 There are many ways of reducing the concentration of phosphorus in water, such as the membrane separation method, chemical precipitation method, biological degradation method, and so on, but each of these methods is highly targeted due to its specic application scope, 6,7 and so it is extremely important to nd a simple, low-cost method which could have a wide range of applications. Chemical adsorption could become one of the most promising phosphorus-containing waste-water treatment methods in the future because of its unique properties.…”

“…T he global need to recycle P from various wastewaters to limit potential environmental pollution, and to produce fertilizers for sustainable food production, was the impetus of many recent studies (Wendling et al, 2013, and references therein). In many cases, synthetic materials were used to capture waste stream P, usually yielding high P recoveries (Wendling et al, 2013). A more environmentally friendly and cost‐effective solution is to use waste materials that otherwise would be landfilled, such as water treatment residuals, which have been proven to preferentially sorb P (Ippolito et al, 2011).…”

We examined P sorption characteristics in Al-based water treatment residuals (Al-WTR) generated from slightly alkaline surface water and in an organic residual composite (WW-Al/O-WTR), produced by using the Al-WTR to treat organic-rich and high P concentration dairy wastewater. Solids from both residuals were examined using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and X-ray diffraction (XRD), and exposed to P additions of 0 to 4000 mg L in a sorption experiment. The Al-WTR removed ∼97% of the added P, whereas WW-Al/O-WTR removed only 78% of the added P in the addition range of 0 to 100 mg P L. With P additions of ≥100 mg L, the removal rate declined to <38% by Al-WTR and to 16% by WW-Al/O-WTR, possibly implying a change in sorption mechanisms. Analysis by XRD indicated that the major mineral was calcite, with some silica and poorly crystalline Al hydroxides. Analysis by SEM-EDS, which used three-element overlay maps of the residual surfaces, indicated that P was sparsely sorbed on both calcic and Al (hydr)oxide surfaces, along with a few clusters, even at low P concentrations of the treated waters. Ternary clusters of P, Al, and Ca were more abundant on the WW-Al/O-WTR. Carbon distribution suggested that organic substances covered Al surfaces. Sorption of P onto WW-Al/O-WTR may be reversible due to relatively weak Ca-P and Al-P bonds induced by the slight alkaline nature and in the presence of organic moieties, enhancing the WW-Al/O-WTR potential to act as a P source, rather than a P sink, in agricultural applications.
