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 … Read more
What are the advantages and disadvantages of single pass and double pass RO as pretreatment for EDI? Electrodeionization must be pretreated with RO for numerous reasons. 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 Purified Water systems … Read more
Hot water sanitization of EDI is important for Ultrapure 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 … Read more
Silica is important in high purity water for power plants. Electrodeionization makes low silica water continuously if you do it correctly. Power plants use high purity water to drive steam turbines. Cogeneration and combined-cycle power plants are highly-efficient, using both exhaust turbines and high-pressure steam turbines. The steam must be of the highest purity. In … Read more
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 … Read more
In June 2018 was the largest water exhibition in the world — Aquatech China 2018. SnowPure was part of this, and you could have found us in Hall 8, Floor 1, Stand H738. (8.1.H738). Electropure China was co-located with Shanghai Yuan Mai Environmental Technology in 2018. We exhibited a wide range of electrodeionization products … Read more
