“…Reduction in UVA254 followed a similar trend as DOC removal for MIEX resin and alum coagulation [29]. Many subsequent researchers have shown similar results of high-DOC and UVA254 removal by MIEX resin [18,23,[30][31][32][33][34][35][36][37]. For example, Boyer and Singer showed greater removals of DOC and UVA254 by MIEX resin than alum coagulation across four different raw waters with the extent of removal increasing as the specific UVA254 (SUVA254) of the raw water increased from 2.0 to 3.8 L/mg·m [31].…”

“…Researchers have also developed alternative testing procedures, such as multiple-loading jar tests and fluidized bed column tests, to investigate other process configurations for MIEX resin. MIEX tests have been conducted using drinking water sources from all over the world, e.g., Australia, China, Japan, Poland, Turkey, UK, and USA [6,8,9,[23][24][25]. Most data for MIEX resin is from NaCl regeneration with limited data from NaHCO 3 regeneration [18,21,[26][27][28].…”

“…By following this procedure, DOC removal by MIEX resin can be expressed as the number of resin bed volumes treated, which is more representative of the fullscale MIEX process. For example, Kitis et al showed 29-39 % DOC removal after 1200 bed volumes of MIEX treatment [23]. Mergen et al applied the multiple-loading procedure to three different water types and showed that MIEX resin exhibited consistent removal of hydrophilic DOC, whereas the removal of hydrophobic DOC steadily decreased with increasing number of bed volumes treated [8].…”

“…Both MIEX and PACl showed minor reductions in MF fouling. In another study, MIEX resin was used in a fluidized bed reactor to treat synthetic wastewater effluent and showed 60 % DOC removal up to 172 bed volumes [57], which is comparable to DOC removal as drinking water treatment but 10 times lower than the throughput volume [8,23]. MIEX resin has also been tested to treat secondary wastewater effluent in preparation for aquifer recharge.…”

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.

“…MIEX is a technology that uses magnetic beads to remove dissolved organic compounds from groundwater [4]. Resin particles are 150-180 µm, macroporous and contain a magnetized component that allows them to act as weak magnets [5]. The MIEX resin used in this process can be readily regenerated by mixing with high concentrated brine.…”

Use of vibratory shear enhanced processing to treat magnetic ion exchange concentrate: A techno-economic analysis

Disposal of waste generated by inland water treatment technologies is highly expensive. The introduction of vibratory shear enhanced processing (VSEP) to treat waste produced from magnetic ion exchange (MIEX) shows benefits in terms of performance and economics. A small VSEP unit fitted with a nanofiltration (NF) membrane is capable of treating up to 15kL of MIEX waste per day, is able remove more than 97% of dissolved organic compounds as well as recover over 80% of waste in the form of permeate. The reuse of permeate to makeup brine has seen significant reductions in salt consumption and waste disposal at Wanneroo Groundwater Treatment Plant (GWTP). During the first year of VSEP operation, salt consumption reduced by 42% and waste disposal was projected to reduce by 23.9%. Further improvements in both cost categories were observed in the second year of operation and considering the same trend is followed, the payback period of the project will occur between the 6 th and 7 th year of operation for discounted analysis and has a positive net present value.

Magnetic poly(glycidyl methacrylate) (m-PGMA) was synthesized and characterized, and its efficiency in removing natural organic matter (NOM) and carbamazepine (CBZ) from synthetic water was studied. The effects of factors such as time and m-PGMA dosage on NOM removal were investigated. Furthermore, magnetic ion exchange resin (MIEX V R ) was used for comparison with m-PGMA in CBZ removal. m-PGMA was found to have a strong magnetic character whose specific saturation magnetization and mass fraction of magnetite were 10.79 emu g À1 and 6.166 wt %, respectively, thus providing additional utility for m-PGMA in slurry form in completely mixed continuous-flow reactors. Lab-scale studies showed that the removal rate rose rapidly with time and reached a pseudo-equilibrium after 30 min. In addition, the highest doses of m-PGMA achieved the highest removal efficiency. After 30 min of contact with 5, 10, and 15 mL L À1 of m-PGMA, the removal rates, based on UV absorbance measurements at 254 nm (UV 254 ), were 56%, 67%, and 79%, respectively, whereas the removal rates of dissolved organic carbon (DOC) were 53%, 60%, and 72%, respectively. Additionally, the scale ultraviolet absorbance values (SUVA) decreased during a 30 min contact time, thereby suggesting that the NOM removed by m-PGMA had greater aromatic character. In multiple-loading tests, UV 254 removal gradually decreased and achieved 18.39% at 1600 bed volume; it was kept constant at this level. Compared to MIEX V R , m-PGMA had a higher CBZ removal rate (27.8% and 34.7% for 20 mL L À1 and 25 mL L À1 of m-PGMA, corresponding to the removal of 200 lg L À1 CBZ).The resulting higher removal rate of CBZ contributed to stronger adsorption, a higher specific surface area, and larger pore volume.
