  • History of Electrodeionization

    Electrodeionization (EDI) history extends back to the mid-1970’s in the USA. Possibly back to Argonne National Labs in the 1950’s as a scientific novelty. However, the first working EDI modules were made by Harry O’Hare in 1977 and 1978, and were tested by the Southern Research Institute (SRI). The concept was “filled-cell ED”, an attempt to use the ED concept to ...

  • Electrodeionization (EDI) using Voltage Control

    In electrodeionization, DC voltage is the force for driving ions out of the stream to be purified. Current is a result of the movement of ions. Both as a matter of physics and as a practical matter, SnowPure recommends using “Voltage Control” for EDI: set the DC voltage potential to the EDI system and walk away–let the current follow the ...

  • Extensive Solutions for Removing Arsenic from Your Drinking Water

    You may not be aware that your water supply has unsafe levels of arsenic in it. If testing proves this to be the case, you must immediately find a form of arsenic water treatment to help you have access to clean drinking water again. Arsenic is a poisonous substance that has innumerable negative health effects on humans. There are several methods of performing arsenic removal from ...

  • Abatement of organic pollutants using fly ash based adsorbents

    The presence of organic pollutants in the environment is of major concern because of their toxicity, bio-accumulating tendency, threat to human life and the environment. It is a well-known fact that, these pollutants can damage nerves, liver, and bones and could also block functional groups of essential enzymes. Conventional methods for removing dissolved pollutants include chemical ...

  • An assessment of nutrient dynamics in streambank soils of the Lower Little Bow River in southern Alberta using ion exchange membranes

    Nutrient dynamics in streambanks may impact nutrient movement to water, and may be influenced by cattle activity, river water level fluctuations, and time. Our objective was to determine the influence of these factors on nutrient (NO3-N, P, S, Fe, Mn, Cu, Zn, Ca, Mg) dynamics in streambanks along the Lower Little Bow River in southern Alberta using Plant Root Simulator or PRS® probes. ...

  • Methods of Purification by Water Innovations, Inc.

    Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...

  • 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 ...

  • Efficient removal of Cd2+ ion from water by calcium alginate hydrogel filtration membrane

    Calcium alginate (CaAlg) hydrogel filtration membrane was prepared using urea as pore-forming agent. The effects of preparation and operating conditions on the removal rate of Cd2+ were researched. The removal mechanism of Cd2+ and the anti-fouling property of CaAlg membrane were investigated. The removal rate of the CaAlg filtration membrane reached over 99.5% within 120 min when 20 ...

  • 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% ...
