  • How to Properly Clean Medical Devices

    When it comes to medical devices cleanliness is crucial. All medical devices, whether they are disposable, implantable or reusable, must be cleaned during the manufacturing process to remove oil, grease, fingerprints and other manufacturing soils. Reusable products must also be thoroughly cleaned and sterilized between each use to avoid infecting patients or causing illness. Reaching the right ...

  • Water Use in the Aerospace Industry

    The aerospace industry, like all water-intensive industries, is moving toward water efficiency in the face of growing global water scarcity. The industry relies on water for a wide range of uses, such as fabrication processes, component washing, production-line cooling, and ...

  • FCE is Important for EDI Electrodeionization System Performance

    EDI, Why FCE is Important for Electrodeionization System Performance The performance of electrodeionization (EDI) systems depends upon several key feed water constituents. When these constituents are considered together a Feed Conductivity Equivalent, or FCE may be determined. ...

  • 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 ...

  • Electrodeionization is a Continuous Process

    Unlike mixed bed DI, electrodeionization (EDI) is continuous. Because electrodeionization is continuous there are no spikes in quality as when mixed beds are changed for batch regeneration. An additional benefit for EDI users is that there is no concern about the timing of changing batches, or planning for the eventual breakthrough of ions in the bed like silica, sodium, or general conductivity. ...

  • For EDI: 1-pass or 2-pass RO?

    Electrodeionization today must be pretreated with RO for numerous reasons. But what are the advantages and disadvantages of 1-pass and 2-pass RO as pretreatment? Many Electrodeionization (EDI) systems using Electropure™ EDI perform very well with 1-pass RO. It’s easy to achieve 17+ Megohm with 1-pass RO. Most USP WFI and ...

  • Heat Sanitization Basics for Ultrapure and Pharmaceutical Water

    Even small numbers of bacteria are a problem for critical water systems like pharmaceutical USP water, dialysis water, and ultrapure water for semiconductor manufacturing. Bacteria are often killed with UV-254, chemicals, and heat. Chemical sanitization is often undesirable or prohibited, creating a steady change-over to pure water systems that can be sanitized with heat. Most ...

  • Operating Electrodeionization in a High-Silica Feedwater Environment

    High silica feedwaters pose two challenges for ultrapure water membrane systems. On the front end, silica can scale the RO membranes, limiting use of some feedwaters and high water recovery. On the back end, silica can scale the IX resins in the electrodeionization (EDI). It is also a challenge to attain the very low ppb levels of silica in the ultrapure product water required by power and ...
