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. 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. The process makes water cleaner and safer at a lower cost than previous methods and in less time. MIEX® resin technology is ideally suited . This work attracted the attention of ICI Australia (now Orica), and they and the CSIRO continued to work on this technology for many years, culminating in two plants, at Osbourne in SA and Mirabooka in WA. 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.

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.

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 applied MIEX doses were 2, 4, 8, and 15 mL/L. 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 treatment for the removal of natural organic matter. Orica Watercare refers to these as Dual Stage and Hi Rate. 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 Instead, he focused on creating a resin that had adequate performance at reasonable cost.

After about a year’s effort, a viable resin had been developed, and it performed well in DOC removal tests at SA Water’s Australian Water Quality Centre.

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. Nitrate is an anion and thus can be removed by ion exchange using the MIEX® Resin. D5 was a disaster: it set into one solid lump in the 200 litre reactor. This is a relatively common process used in drinking water … MIEX® process as a pre-treatment removed a majority of small molecular weight organic matter (500–1000 Da). to treat the highly coloured Cape waters of South Africa. Introduction Incising demand for high quality drinking water results in seeking new effective process es of water treatment… Keywords: MIEX®DOC; Ultrafiltration; Natural organic matter; Integrated process 1. The MIEX® advanced process, systems and resins were developed over an extended period stretching back to the mid 1980s. We had successfully scaled up the resin synthesis by a factor of almost 1 000 by September 1995 – or so we thought. Of these, only three are operating in Australia: at Mount Pleasant in South Australia, Wanneroo in Western Australia and Airey’s Inlet, Victoria. The removal of chloride on MIEX resin is an ion-exchange mechanism. [�d9:;@�����Z 0d�l���X,�� �P�Pɰ�a=�6&g�h�G�\��e��w�$s�0�0p3�b����8�~�\�u��v�]d�gW� ���}'�voP0 �7@� ��]�

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. The advantages of using the MIEX® resin as a pre-treatment step allows for; ¾ improved final water quality, ¾ reduced THM formation, It is a continuous ion exchange process performed in tanks, which is maintained in a steady state by the withdrawal and regeneration of loaded resin, and the return of this resin to the process. MIEX® was far more successful in the USA and Europe. The next step up was 200 litre: the first two batches were quite poor, with small particle size, and poor magnetic oxide incorporation. METHODS: In this study, the uptake of estradiol by a combined magnetic ion exchange resin - ultrafiltration process (MIEX-UF) was investigated. water quality.
