This EDI module also has a membrane stage

Kate Torzewski

Septron Bio-Safe is said to be the world’s first electro-deionization (EDI) module with an integrated membrane stage. It is based on proven and patented spiral-wound technology and has an additional membrane stage for removal of particles and bacteria. The EDI module is available in a cold-water version and a version that can be sanitized with hot (>80°C) water. Both versions are available in various sizes with outputs of 500 to 3,000 L/h. The combination of this module with a preceding reverse-osmosis stage makes it possible — without additional ultrafiltration — to produce highly purified water with bacterial counts of less than 10 calorie forming units per 1,200 mL. The module can be retrofitted on existing Osmatron systems. Hall 4.1, Stand F3–G7 — Christ Water Technology Group, Aesch, Switzerland
