2. The MIEX® Resin Process The process for DOC removal based on the MIEX® resin includes resin contacting with water, resin separation and recycle, and resin regeneration. Orica then constructed its own $10 million, 300 tonnes per year MIEX® resin manufacturing plant in Melbourne to supply resin to both Australia and the world. This is a relatively common process used in drinking water treatment for the removal of natural organic matter. Surprisingly, they asked CSIRO if they could make the required resin – about 20 batches – on the 200 litre scale! [Source: CSIRO], CSIRO’s 200 litre, 2 storey tall, Process Bay reactor. As Mat Ballard recalled: The first steps up to 1.2 litre and then 2.0 litre were successful, but were as far as we could go in the lab. Subsequently, the exhausted MIEX was regenerated with a 10% w/w NaCl solution. End-user response animation. In the high reactor, raw water is fed to the base of the reactor vessel and is mixed with the MIEX ® resin and the ion exchange process occurs in a uniformly mixed fluidized bed. Ion-exchange resins are widely used in different separation, purification, and decontamination processes.The most common examples are water softening and water purification.In many cases ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites.Also, ion-exchange resins are highly effective in the biodiesel filtration process. Instead, he focused on creating a resin that had adequate performance at reasonable cost. A further hiccup was encountered when supply of one of the critical raw materials in the pre-mix ceased, and a substitute had to be found rapidly. an ion exchange process used in drinking water treatment. Frantic lab investigations slowly tracked down the problem: the pre-mix was temperature sensitive. Ixom Watercare and two leading Australian research organizations (Commonwealth Scientific Industrial Research Organization and South Australian Water Corporation) worked together to develop a unique ion exchange process for the removal of DOC from potable water … 0000003986 00000 n (DOC) and improving the quality of potable water.

IX has been introduced by the WHO as a nitrate removal technology and approved as the Best Available Technology (BAT) for nitrate removal by US EPA. The MIEX® Treatment Process is an advanced ion exchange process that uses MIEX® Resin to remove target contaminants from water and wastewater streams. This was a small plant designed to test MIEX® and other new technologies. the resin can be used in a stirred tank instead of a column, because the particles are dense and will stick magnetically to each other when stirring stops, they form large clumps that settle rapidly. MIEX® DOC Known for its ability to remove up to 80% of Dissolved Organic Carbon (DOC) This first generation of MIEX® resin helps water treatment plants become compliant with stage 2 regulations for Disinfection By-Products (DBPs) and lower their coagulant and total oxidant demand. Raw water from the inlet main enters at the bottom of the contactor and comes into contact with the MIEX Resin. %PDF-1.3 %���� MIEX® is now a significant part of the Orica Watercare business. Central to the system is a micro, strong base, magnetic ion exchange resin, which was specially developed and optimised for DOC removal. The process makes water cleaner and safer at a lower cost than previous methods and in less time. The MIEX® process uses a specially designed resin. The MIEX process uses a specially developed magnetised ionic resin to attract the negatively charged dissolved organic carbon (DOC) compounds that can cause colouration in untreated water. 0000001218 00000 n MIEX® advanced ion exchange solutions are applied using a MIEX® or MICo® process, via MIEX® treatment systems (MagnaPak®, Mini, Dual RateStage, High Rate or Integra) and utilizing MIEX® resins (DOC or GOLD) or (Plus) resin and media blends. A full-scale (110 ML/d) potable water treatment plant (WTP) based on the MIEX process, an innovative new process based on a strong base anion-exchange resin with magnetic properties, has been operating in Perth Western Australia since 2001. The next step up was 200 litre: the first two batches were quite poor, with small particle size, and poor magnetic oxide incorporation. The MIEX®1 Resin process was developed in Australia for the removal of natural organic material in water treatment. MIEX is an innovative ion exchange resin that cost-effectively removes dissolved organic carbon (DOC), a precursor to disinfection by-products (DBPs) in drinking water. the large clumps also mean that the primary resin beads can be made an order of magnitude smaller than conventional resin beads, and hence absorb ions from solution many times faster. This is a relatively common process used in drinking water treatment for the removal of natural organic matter. used in water treatment to remove unwanted contaminants. Specifically, it can increase the amount of alum that is required for flocculation, and it can also react with chlorine or ozone to form small quantities of toxic tri-halo methanes (THMs). While extremely successful, conventional ion exchange suffers from three problems: The problems with conventional ion exchange led to the idea of using a magnetic ion exchange resin in a stirred tank, and recovering the resin through its high density and/or magnetism. The process is a pre-treatment incorporating MIEX® DOC resin for the removal of DOC. The first two batches, at 15 and 20 litre were fairly successful, though the resin particle size was too small. In the end, almost 200 batches of MIEX® resin were made at CSIRO. We had successfully scaled up the resin synthesis by a factor of almost 1 000 by September 1995 – or so we thought. Armed with that information, the batches from D8 onwards were more successful, and an ongoing lab program helped to continuously improve resin quality. The MIEX® Treatment Process The MIEX® Treatment Process is an advanced ion exchange process that uses MIEX® Resin to remove target contaminants from water and wastewater streams. The team involved in the development of the MIEX® process were as follows: The development of the MIEX® process has been recognised by the following awards: We are committed to child safety and to the implementation of Child Safe principles and procedures. In the 1980s Prof Don Bursill of South Australia Water demonstrated that if DOC, which is a significant problem for Adelaide, could be removed from raw waters before treatment, there were considerable reductions in both alum and chlorine usage. The resin was then patented, and in later years several variants and processes using it were also patented. Afterwards supernatant was decanted into a stirred magnetically cell for the subsequent UF treatment. MIEX Resin Treatment Alum Coagulation Clarification Raw Water Filtration Product Water Pre-chlorine Alum Figure 4: Wanneroo GWTP Process, including MIEX® Plant The results from Trial 2 showed that greater than 75% DOC and 90% NSRS removal could be consistently achieved when the resin process was used in conjunction with conventional or He then had the insight that a resin like the ICI/CSIRO SIROTHERM® might be able to do the job because it did not require the use of packed columns. Process Parameters Optimization of Gallic Acid Removal from Water by MIEX Resin Based on Response Surface Methodology . CSIRO also discovered that smaller batches were less prone to setting solid. 0000000814 00000 n Placement of MIEX® Resin Technology in the Treatment Train The MIEX® resin technology was tested using raw water as the first step in the overall water treatment process. The resin is a strong base anion exchange developed with improvements resulting in high affinity for the removal of dissolved organic carbon (DOC). Mat Ballard, who had just joined CSIRO from ICI, was selected to lead the research program. Introduction Incising demand for high quality drinking water results in seeking new effective process es of water treatment… The MIEX process is a novel ion exchange approach specifically developed for the removal of the dissolved organic content (DOC) from water. This is a relatively common process used in drinking water … By 2011 there were 37 MIEX® systems operating internationally with a further 8 under construction. MIEX resin and its process were developed by the Australian company and research organizations Orica, Commonwealth Scientific Industrial Research Organization, and South Aus-tralianWaterCorporation.ThepatentsonMIEXresinandthe MIEX process were issued in 2001 and 2003, respectively The water we drink comes mostly from dams and rivers. https://csiropedia.csiro.au/MIEX-water-purification-process [Source: CSIRO]. Since MIEX is in a slurry form, its dose was determined based on v/v concentration. Orica Watercare refers to these as Dual Stage and Hi Rate. 0000073035 00000 n To this end, the resin was allowed to settle in a conical tube and was placed above a magnet to accelerate the settling. Ballard MJ, 2011, Personal communication. For the MIEX-UF hybrid process, briefly, appropriate dose of MIEX resin was added to feed water and mixed for 30 min followed by 30 min of settling. [Source: Mat Ballard, CSIRO], Lab-scale ion exchange. MIEX is a commercially available anion exchange resin and an ion exchange process used in drinking water treatment. It removed a majority of small molecular … 0000001197 00000 n Unfortunately, both surface and bore water in Australia often have high levels of DOC. it is a batch, not a continuous process, and so harder to monitor and control. MIEX Resin Treatment Alum Coagulation Clarification Raw Water Filtration Product Water Pre-chlorine Alum Figure 4: Wanneroo GWTP Process, including MIEX® Plant The results from Trial 2 showed that greater than 75% DOC and 90% NSRS removal could be consistently achieved when the resin process was used in conjunction with conventional or A much larger plant opened at Wanneroo in Western Australia in 2002 and a small plant at Airey’s Inlet, Victoria in 1997.

The 99.9% recovery figure is based on the resin mass leaving the MIEX process in the treated water stream. This is a relatively common process used in drinking water treatment for the removal of natural organic matter. Orica then contracted with SA Water to install the MIEX® process into a new water treatment plant to be built at Mount Pleasant in the Adelaide Hills. Once production was under control, Orica extended the production run to 40 batches, then extended it again when they won a contract to install MIEX® at the Wanneroo water treatment plant in WA. We used a unique magnetite media (magnetic) filter to capture resin fines from the MIEX process. MIEX® is an innovative process technology developed by Orica Watercare in conjunction with two leading research organisations: CSIRO Division of Molecular Science and South Australia Water Corporation. He realised that this was not possible using conventional ion exchange due to a ‘Catch-22′ situation: the water had to be treated before it could be put through ion-exchange columns, but it needed to have the DOC removed before it was treated. MIEX® resin regeneration equipment is supplied as modular, skid-mounted systems. The water we drink comes mostly from dams and rivers and contains various impurities such as dirt, leaves, Escherichia coli, giardia, and dissolved organic carbon (DOC). The key process units include a gravity fed, high rate contactor vessel containing the MIEX Resin and the Resin Regeneration skid. Unfortunately for the people of Adelaide, MIEX® has not been installed at any other water treatment plants in that city. A novel magnetic ion exchange resin called MIEX Resin is being utilized in potable water treatment, which indicates significant advantages. In 1953, Earl C Herkenhoff from American Cyanamid Co patented magnetic ion exchange, in which he incorporated magnetite into a phenolic ion exchange resin, and claimed that the resin could be recovered by magnetic means. The MIEX® resin process uses mixed tanks for contacting resin with water. Two nonionic resins were used to fractionate NOM before and after treatment with magnetic ion exchange (MIEX®) and a powdered activated carbon. A full-scale (110 ML/d) potable water treatment plant (WTP) based on the MIEX process, an innovative new process based on a strong base anion-exchange resin with magnetic properties, has been operating in Perth Western Australia since 2001. The applied MIEX doses were 2, 4, 8, and 15 mL/L. School of Civil Engineering and Architecture, Anhui University of Technology, 59 Hudong Road, Maanshan 243002, China. MIEX resin and its process were developed by the Australian company and research organizations Orica, Commonwealth Scientific Industrial Research Organization, and South Australian Water Corporation.

When made at small scale, it remained cool, but when made at commercial scale, it became quite hot. an ion exchange process used in drinking water treatment. The WTP treats groundwater with magnetic ion exchange (MIEX¨) treatment technology. SA Water: Don Bursill, Mary Drikas, Jim Morran. A very small amount of resin (5-10 mL settled resin per litre water) is used to exchange organics from water during 15-30 min detention time in a continuous, stirred tank reactor. The MIEX® Mini is a packaged ion exchange system that uses MIEX® or MICo® Resins to remove targeted species from water and waste-water streams in low flow applications. MIEX® Resin The name MIEX® … The treated water was collected for PFAS analysis to evaluate the adsorption efficiency of the pristine resin. This method removes dissolved organic carbon in the raw water, followed by pH adjustment and deep-bubble aeration, resin-polishing filters, disinfection, fluoridation, and two 1-MG ground storage tanks before distribution. Abstract: The new developed ion exchange process SIX presents an advanced solution for a world-wide challenge: How to remove NOM/DOC as a first step in surface water treatment to improve efficiency of downstream processes and to improve water quality. Magnetic ion exchange (MIEX®) resin can remove a majority of hydrophilic compounds and a significant amount of hydrophobic compounds from biologically treated secondary effluent within a short contact time of 20 min.

[Source: CSIRO], Process diagram of a MIEX water treatment plant. While there were several routes to a possible resin for DOC removal, Ballard realised that most were not commercially viable due to toxicity or cost of raw materials. The MIEX® process can also be used to significantly reduce treated water color levels from 60% to 95% through the removal of DOC. 0000002786 00000 n DOC can have a major impact on treated water quality and the treatment process, including: reacting with disinfectants to form harmful disinfection by-products (DBPs), influencing the appearance and water color, taste and odor, by Qiang Zhou 1, Lei Ding 1,2,*, Yunhua Zhu 1,2, Meiying Zhong 1,2 and Chuchu Yang 1. MIEX®DOC process revealed to be more efficient in DOC removal than conventional treatment achieving the efficiencies in the range of 61-91 %, lowering disinfection by-products formation potential of the water. To make it suitable for drinking, water must be treated so that the suspended matter is removed, and any pathogens killed by disinfection with chlorine or ozone. The MICo® process and MIEX® Plus resin blend that Ixom recommends will depend on your unique treatment needs. In: 2nd European Conference on filtration and separation, Compeigne, France, 12 October 2006. In conventional ion exchange the plastic beads are packed into a large steel or plastic column and impure water forced through under pressure to produce water of higher quality. CSIRO then went to a local manufacturer – Yorkshire – who made the pre-mix in their larger scale lab equipment. Unfortunately, the process did not scale up to industrial scale well, both plants were quickly closed, and research into the area almost ceased. The MIEX® process has been described by US water specialists as potentially the ‘magic bullet’ the world’s water utilities have been searching for and is now a significant part of the Orica Watercare business. Therefore, MIEX resin is a promising technology for the removal of chlorite from aqueous solution. Kelly: For more than ten years now, Oracle Watercare's been at the forefront of advanced ion exchange for water treatment, especially in the municipal market. The objective of the study was to compare the treatment efficiency obtained with the MIEX®DOC process and ultrafiltration as well as to investigate the effect of MIEX®DOC water pretreatment on the performance of ultrafiltration membranes.

Methods: In this study, the uptake of estradiol by a combined magnetic ion exchange resin - ultrafiltration process (MIEX-UF) was investigated. Solution pH exhibited a remarkable impact on the adsorption process and the absorbed concentrations of the tested antibiotics were obtained around the neutral pH. 0000003427 00000 n This led to the choice of glycidyl methacrylate (GMA) as the backbone of the resin, and maghemite (γ-Fe2O3) as the magnetic oxide. The first MIEX® water treatment plant was at Mount Pleasant in South Australia, and it was commissioned in 2001. What makes MIEX unique is a magnetic component that allows the resin to be used in a continuous … Resin loss. The surface water became less humic after MIEX treatment, as demonstrated by the decrease in A/T ratio compared to the raw surface water, but then humic content increased with continuous resin use. 0000006689 00000 n The advantages of magnetic ion exchange are: Magnetic ion exchange has a long history. In addition, it can promote bacterial re-growth in pipes by acting as a ‘food’. MIEX® Treatment Systems have small footprints, very low waste volumes and are not subject to chromatographic peaking, allowing ion exchange to be used in a wide variety of applications and throughputs. 0000001736 00000 n The resin and the process of making it had to be scaled up – and this led to some very interesting times! Dissolved organic carbon organic carbon Subject Category: Miscellaneous see more details can be removed effectively as well as chlorite and chlorate using MIEX resin in real water. The persistence of these pharmaceuticals and inefficient removal by water treatment lead to accumulation in surface water and effluents with negative effects for aquatic life and human health. Nitrate is an anion and thus can be removed by ion exchange using the MIEX® Resin. Of these, only three are operating in Australia: at Mount Pleasant in South Australia, Wanneroo in Western Australia and Airey’s Inlet, Victoria. D5 was a disaster: it set into one solid lump in the 200 litre reactor. The most common application of IX is softening, but there are many kinds of resin, and anion IX resins can be used for the removal of anions like nitrate, DOC, and arsenate. It was one thing to make 60 g of resin in a 200 ml reactor in the lab, and quite another to make enough to supply a water treatment plant – even a small one of several megalitres per day. MIEX® Treatment Systems have small footprints, very low waste volumes and are not subject to chromatographic peaking, allowing ion to exchange be used in a wide MIEX is an innovative ion exchange resin that cost-effectively removes dissolved organic carbon (DOC), a precursor to disinfection by-products (DBPs) in drinking water. MIEX®DOC process revealed to be more efficient in DOC removal than conventional treatment achieving the efficiencies in the range of 61-91 %, lowering disinfection by-products formation potential of the water. The resin has a magnetised component which allows the particles to act as weak magnets, giving them unique settling and other handling characteristics. In contrast, the secondary effluent A/T ratios remained constant at ∼2.9 across the range of BV treatments (changes were statistically insignificant). MIEX® is used as a pre-treatment at the start of a conventional water treatment plant. trailer << /Size 99 /Info 68 0 R /Root 81 0 R /Prev 887971 /ID[<28bc7466c00207c9f54a07cfb78a94ee><28bc7466c00207c9f54a07cfb78a94ee>] >> startxref 0 %%EOF 81 0 obj << /Type /Catalog /Pages 69 0 R /JT 79 0 R /PageLabels 67 0 R >> endobj 97 0 obj << /S 238 /L 330 /Filter /FlateDecode /Length 98 0 R >> stream Groundwater treatment plant ( 2006 ) impact of continuous MIEX use on downstream treatment. 500–1000 Da ) disaster: it set into one solid lump in the USA and Europe advantages of ion...
