Water Online Radio: Tell us about the new MICO process and how it differs from MIEX. In 1965 Don Weiss and others at CSIRO became interested in the application of this concept to desalination, and developed a resin and a process called SIROTHERM®. The resin was then patented, and in later years several variants and processes using it were also patented. 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. 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.

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, DOC itself is harmless, but it can interfere in these treatment processes. 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 MIEX´® DOC resin … MIEX® Resin The name MIEX® … MIEX® was far more successful in the USA and Europe. This is a relatively common process used in drinking water treatment for the removal of natural organic matter. Of these, only three are operating in Australia: at Mount Pleasant in South Australia, Wanneroo in Western Australia and Airey’s Inlet, Victoria. [Source: Mat Ballard, CSIRO], Lab-scale ion exchange. used in water treatment to remove unwanted contaminants. CSIRO then went to a local manufacturer – Yorkshire – who made the pre-mix in their larger scale lab equipment. Resin loss. Ion exchange is used industrially to purify water to high quality. 0000001372 00000 n In: 2nd European Conference on filtration and separation, Compeigne, France, 12 October 2006. Therefore, MIEX resin is a promising technology for the removal of chlorite from aqueous solution. Mat Ballard, who had just joined CSIRO from ICI, was selected to lead the research program. 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. 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. 0000001531 00000 n 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. What makes MIEX unique is a magnetic component that allows the resin to be used in a continuous … Unfortunately, the process did not scale up to industrial scale well, both plants were quickly closed, and research into the area almost ceased. The fully assembled regeneration skids have a small footprint allowing for low installation costs. 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. The process is a pre-treatment incorporating MIEX® DOC resin for the removal of DOC. We had successfully scaled up the resin synthesis by a factor of almost 1 000 by September 1995 – or so we thought. https://csiropedia.csiro.au/MIEX-water-purification-process 0000001736 00000 n 0000003986 00000 n 0000000814 00000 n 0000001218 00000 n Introduction Incising demand for high quality drinking water results in seeking new effective process es of water treatment… 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. The objective of this article is to analyze characteristics and application of MIEX Resin in engineering projects, and hence provide critical review on merits and demerits of the resin. 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. The 99.9% recovery figure is based on the resin mass leaving the MIEX process in the treated water stream. DOC removal efficiency at Lever WTP depends largely on the raw water quality and ranges from 28 % for water of moderated quality to 89 % of significantly deteriorated quality. 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 [13††, 14††]. What makes MIEX unique is a magnetic component that allows the resin to be used in a continuous ion exchange process… The MIEX® Treatment Process is an advanced ion exchange process that uses MIEX® Resin to remove target contaminants from water and wastewater streams. To make it suitable for drinking, water must be treated so that the suspended matter is removed by flocculation using alum or iron salts and any pathogens killed by disinfection with chlorine or ozone. 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. 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. Central to the system is a micro, strong base, magnetic ion exchange resin, which was specially developed and optimised for DOC removal. Note the narrow piping. 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 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. 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. In contrast, the secondary effluent A/T ratios remained constant at ∼2.9 across the range of BV treatments (changes were statistically insignificant). Published by Elsevier Ltd. 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. Two bed volumes of the solution were added into a conical tube with the exhausted resins and stirred for 30, 60, 90 and 120 min. MIEX® resin technology is ideally suited .
