Flowrex - Deionization System
EDI or Electro Deionization is a very effective tool to replace the IX Demin system (using IX Resin). The use of IX Demin as Water Purification to reduce mineral content (TDS) is starting to be abandoned. Where this system has weaknesses, among others: high OPEX (chemical consumption - acid and caustic are quite expensive) as well as a relatively high risk handling process due to the use of chemicals that tend to be dangerous (acid and caustic).
The use of EDI, on the other hand, offers: very low OPEX (no regeneration process required), produces very pure water with very low TDS (TDS < 0.2 ppm) and stable operation and tends to be easier and safer (does not use harmful chemicals - acids and caustics).
