  • Ion Exchange Systems.

    When properly applied, ion exchange for concentrated ion recovery is by far the best available technology. Where effluent streams can be filtered and ions requiring different regenerants can be segregated, ion exchange is usually the most cost effective and least capital intensive solution. We provide 4 levels of integration to cover most applications and capital budgets. The variations in the ...


  • Magnetic Ion Exchange Solves Problems

    In 2004, Big Elk Water Association, near Estes Park, Colo., earned the unenviable Environmental Working Group label of Colorado water system with the worst quality water. Despite multiprocess treatment, BEWA’s finished water had some of the highest concentrations of total trihalomethanes (TTHMs) and haloacetic acids (HAA5) in the state. BEWA delivers water to about ...

  • White paper - Ion Exchange Theory

    Ion exchange is the removal of unwanted “charged” particles, called ions, from raw water. In this process the ions are transferred to a solid particle, called an ion exchanger, which accepts these ions while returning an equal number of desirable ions. The exchangers are made of porous plastic resin, which gives them many “exchange sites”. In the basic reaction, an ion ...

  • What is an Ion Exchange System and How Does it Work?

    Ion exchange (IX) systems are used across a variety of industries for water softening, purification, and separation purposes. While the chemistry of individual ion exchange reactions vary from one application to the next, IX is a treatment process where dissolved ions are replaced by other, more desirable, ions of a similar electrical charge. If you’re wondering whether IX is right for your ...

  • Introduction to Ion Exchange Part 1

    IMPURITIES IN WATERWater is often referred to as the 'universal solvent' as it will dissolve small amounts of everything it touches. Water collects or dissolves a variety of mineral salts, organic compounds and suspended solids as it flows over the earth's surface and through the ground. These impurities make water undesirable for use in many applications. It is, therefore, important to ...


  • Types of Water Treatment Systems

    There are different types of water treatment systems, and knowing the difference between them can help you make an informed decision on just what type of treatment you’ll need for your water. There is no best water treatment system that will meet everyone’s needs—each system has its benefits and deficiencies. Here are a few ...

  • Ionex- Versatile ion exchange technology for Nitrate removal

    Belgian separations technology company PuriTech (www.puritech.be) has designed an ion exchange system that improves liquid–resin contact efficiency while reducing plant operating costs and capital expenditure. Targeted at a broad range of industries, one area where the system is now showing its strength is in the removal of nitrates from drinking water, asPuriTech's Filip ...

  • An Evaluation of Magnetic Ion Exchange (MIEX®) for NOM Removal

    A new process for the removal of natural organic matter (NOM) was developed in Australia by Orica Watercare and South Australian Water Corporation. It employs a strongly basic anion exchange resin to remove NOM from water. In the first stage of the process, the (180 μm) MIEX® resin is mixed with the water to be treated and its small size encourages rapid removal of NOM. The resin beads also ...

  • Combined bio-regeneration and ion-exchange system for perchlorate removal

    In order to prove that perchlorate-laden resins could be bio-regenerated through direct contact with perchlorate-reducing bacteria (PRB), a combined bio-regeneration and ion-exchange (IX) system was operated. Two kinds of perchlorate-laden resins, nitrate-selective A520E and perchlorate-selective A530E, were successfully regenerated by PRB cultivated under anaerobic conditions. The ...

  • Novel ion-exchange system softens produced water for steam generation

    As California entered a period of severe drought in 2008, the challenges of using thermal methods to extract heavy oil became compounded by the difficulty of securing freshwater sources from which to generate the high-quality steam that these methods require. In an effort to manage the crisis, then-Gov. Arnold Schwarzenegger proclaimed a state of emergency and enacted widespread ...

  • Power Industry using Micro-Media Filtration and short-bed ion exchange

    With the demand or higher efficiencies, lower maintenance and operating costs for boilwers and turbines, high-purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra upercritical boiler pressures and temperatures, require high-purity water that approaches quality levels at the theoretical levels. ...

  • Temperature effect on ion exchange equilibrium between CMX membrane and electrolytes solutions

    Ion exchange equilibrium for three systems involving monovalent and divalent ions has been investigated over various temperatures (283, 298 and 313 K) using CMX cationic exchange membrane. All experiments were carried out at 0.1 mol/L. Ion exchange isotherms for the binary systems (Na+/K+), (Na+/Ca2+) and (K+/Ca2+) were established at ...

  • Biologically active ion exchange (BIEX) for NOM removal and membrane fouling prevention

    The natural organic matter (NOM) removal efficiency and regeneration behavior of ion-exchange filters with promoted biological activity (BIEX) was compared to operation where biological activity was suppressed (i.e. abiotic conditions). The impact of BIEX pre-treatment on fouling in subsequent ultrafiltration was also investigated. Biological operation enhanced NOM removal by approximately 50% ...

  • CO2 adsorption over ion-exchanged zeolite beta with alkali and alkaline earth metal ions

    The need to reduce anthropogenic CO2 emissions has been the driving force to consider new approaches and novel ideas for CO2 management, and carbon capture and storage (CCS) are considered to potentially be the most effective means to alleviate the problem. The most common method for CO2 capture is via gas absorption, with monoethanol amine (MEA) being the most widely used solvent. The current ...
