“…It is crucial 19 for researchers to develop effective technologies for phosphate 20 removal in water and wastewater treatment systems. Among 21 various available technologies for phosphate decontamination, the 22 adsorption method is relatively simple, economical, and highly 23 efficient [5,6]. Various types of materials have been used as 24 adsorbents, such as Fe-Mn binary oxide [7], a metal oxide 25 adsorbent derived from manganese ore tailings [8], nanostruc- 26 tured Fe(III)-Cu(II) binary oxides [9], mesoporous Cr-Zr binary 27 oxide nanoadsorbent [10], magnetic Fe-Zr binary oxide [11], 28 aluminum compounds [12][13][14], and hydrous zirconium oxide- 29 based nanocomposites [4].…”

“…11,12 More recently, studies have found that during the processes of removing excessive P in lake water with several materials including WTRs, WTRs also presented minimum undesirable effects to the water chemistry. 20 Therefore, as a safe "waste" with high P adsorption capability, WTRs may also be an ideal material for controlling the internal P loading from sediments for lake restoration.…”

ABSTRACT: A novel approach of using water treatment residuals (WTRs) to reduce the internal phosphorus (P) loading from lake sediments under varied levels of dissolve oxygen (DO) has been investigated in this study. This may lead to a "win-win" technique for lake restoration in large scale. Small scale experimental results showed that WTRs can significantly reduce the contents of the internal P loading from the sediments under different DO levels. In particular, under high DO level (5-8 mg L -1 ), P loading can be reduced by %…... Analysis of inorganic P fractionation of sediments indicated that the reduced internal loading-P is in the 2 stable form of NaOH-P. The P nuclear magnetic resonance spectroscopy ( 31 P NMR) analysis of NaOH-EDTA extracts of the sediments further demonstrated that WTRs have lower potential for the active organic P, e.g. orthophosphate monoesters and pyrophosphate, to be released to overlaying water. Moreover, application of WTRs also had marginal effects on Fe and Al concentrations and pH of the overlaying water. Therefore, as a "waste", WTRs are appropriate for controlling the internal P loading for lake restoration purpose.

“…MIEX resin has also been investigated for removal of other inorganic anions including sulfate [18,33], nitrate [26,33], phosphate [70,71], chromium(VI) [16], arsenic(V) [16], iodide [67••], and perchlorate [72,73], some of which may compete with DOM for exchange sites on MIEX resin. The extent of removal of inorganic chemicals depends on the initial chemical concentration, MIEX resin dose, and competing species.…”

This article provides a state-of-the-art review on the uses of magnetic ion exchange (MIEX) resin in drinking water and wastewater treatment, with emphasis on removal of dissolved organic matter (DOM) from drinking water and wastewater, regeneration efficiency, removal of inorganic and synthetic organic chemicals, comparison with other anion exchange resins, and integration with other physical-chemical processes. Through laboratory jar tests, pilot plant tests, and full-scale installations for a variety of drinking water sources, MIEX resin can achieve 30-80 % removal of dissolved organic carbon (DOC), which is often higher than alum or ferric coagulation. In addition, MIEX resin has been shown to remove hydrophilic, transphilic, and hydrophobic fractions of DOM and a wide range of molecular weight fractions of DOM. As a result, MIEX pretreatment results in substantial reductions in the formation of trihalomethanes and haloacetic acids upon chlorination. MIEX resin can achieve bromide removal in the range of 10-50 %, with higher bromide removal in waters with low DOC, low alkalinity, and low sulfate. However, there are commercially available anion exchange resins that are more selective for bromide than MIEX resin. MIEX resin has been investigated in combination with coagulation, activated carbon adsorption, membrane separation, lime softening, and ozonation. MIEX pretreatment has been shown to reduce downstream chemical requirements and improve the operation of downstream processes. This is most evident for coagulation and ozonation where the coagulant dose can be reduced by 50-75 % and the ozone concentration can be increased by 40-65 %. In general, MIEX pretreatment shows minor reductions in membrane fouling. Future research should continue to investigate the integration of MIEX treatment with other processes.
