Ion Exchange Australia supplies ion exchange resins for a variety of applications from the most typical paalications in water treatment to very specific areas. Below are highlighted major applications of ion exchange resins as well as some promising areas. Please contact us if you have questions about any particular usage of the resins.

     Water Purification

Water treatment is the most common application and the largest market for ion exchange resins. It includes a number of processes such as softening, deminiralisation, dealkalisation, removal of organic compounds, iron and manganese removal, removal of arsenic, boron and nitrates, polishing and other processes. Ion exchange is used for both domestic and industrial water purification. Domestic usage mainly consists of ion exchange filters. The industrial water treatment with ion exchange varies depending on the industry. Each industry, such as food and beverage, power generation, chemical and petrochemical, electronic and semiconductor, might have specific applications for IX resins. Below are given some other examples of such applications.

     Hydrometallurgy

Our particular interest is the hydrometallurgical recovery of valuable metals from solutions and pulps using continuous ion exchange technology and resin in pulp process. At this stage the ion exchange technology is a mainstream process in the hydrometallurgical extraction of uranium and gold and a supplementary process in the hydrometallurgy of base and rare metals. However, due to a number of technical and economic advantages the ion exchange technology and resin in pulp in particular could become mainstream processes for the recovery of metals from low grade ores, cut-offs, tailings and metallurgical wastes.

     Food and beverages

The major application of the ion exchange in the food and beverages industry is the preparation of drinking water. In addition to that there is a number of industry specific applications such as decolorisation and colour stabilisation of sugar, honey and sweeteners, removing traces of pesticides, heavy metals and other harmfull compounds, demineralisation of citric and lactic acids and other food additives, control of food and drinks acidity, refining of milk products, separation of organic compiunds. The food grade resins are produced with higher purity.

     Pharmaceuticals

Ion exchange resins and polymeric adsorbents are widely used in traditional pharmaceutical industry as well as Chinese herbal medicine. Some industry specific applications include extraction, separation and purification of vitamins, antibiotics, streptomycin, penicillin, enzymes, hormones; removal of saponins, glycosides, flavonoids, alkaloids, phenols, clindamycin phosphate ester, anthraquinone, cephalosporins and others; decoloration of pigments and amino acids; removal of water- and alcohol-soluble pigments and impurities. In herbal medicine the resins are used for extraction of bio-active compounds and antioxidants from ginsengsides, ginko, jasmine, tea and other plants and herbs.

     Waste water treatment

Our special ion exchange resins for waste water treatment are designed to deal with industrial process and waste water. fIn particular they can be used to remove heavy metals, pesticides, phenolic compounds, derivatives of salicylic, formic and other organic acids, organic solvents and other substances. Many useful and valuable compounds can be recycled and reused, which develops new sources of profits for chemical and pharmaceutical companies while balancing the cost of environment protection.

 

     PROMISING APPLICATIONS

BIODIESEL   The development of the biodiesel production technology is becoming one of the promising methods to produce renewable fuel. A part of this technology is to use ion exchange resins to adsorb free glycerin and trace methanol and water as well as to remove residual catalyst. It makes the purification of crude biodiesel a more cost effective process.

WINE AND BEER   Wine and beer industries are important part of the Australian economy. Ion exchange is able to contribute to the quality improvement of the Australian wine and beer. The major application of ion echange in this area is the beverage stabilisation by controlling tartare content and acidity, removing excessive amount of polyphenols and proteins, improving chemical and physical indices of colour value.

FRUIT JUICES   Specialised resins have been developed for juices processing. The variety of juices include apple, orange, pear, pineapple, grape and pomegranate juices. The ion exchange resins are used to improve physical and chemical indices of the products such as color value, light transmittance, turbidity, to remove traces of pesticides, patulin and other harmfull substances; to ajust sugar-acid ratio; to control acidity and bitternes and to stabilise colour, taste and flavour of the juices.

ENZYME CARRIERS   Enzyme products are widely used particularly in biotechnology and food processing. Specialised enzyme vector resins satisfy various requirements for solidified enzyme carriers. These resins feature larger pore volume, higher specific surface area, higher enzyme load, better mechanical properties and higher durability.

SPECIALTY RESINS   Ion Exchange Australia provides a variety of resins for specialised applications. IN particular those applications include removal of arsenic, boron, nitrates and fluorides from potable water, extraction of gallium, lithium, and other rare metals, chromatographic ion determination and separation.

METAL FINISHING AND ELECTRO PLATING   Waste water from metal finishing and electro plating plants may contain heavy metals (copper, nickel, chromium) and cyanides. Chemicals methods of waste water treatment are currently utilised to remove those harmfull compounds. Ion exchange technology provides an opportunity to recycle both metals and cyanides and therefore to solve ecological issue and improve an economic characteristics of the plants.
