EDI Module with Membrane Stage

With Septron Bio-Safe, Christ now offers the world’s first electro-deionisation module with an integrated membrane stage. It is based on the 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 which can be sanitised with hot ­water. Both versions are available in various sizes with outputs of 500‑–‑3,000 l/h. The combination of this module with a preceding reverse osmosis stage makes it possible to produce Highly Purified Water (HPW) with bacterial counts of ≤ 10 CFU/100 ml. The cold-water version of the Septron Bio-Safe offers the benefits of high pure water quality and low energy costs and is particularly suitable for pharmaceutical ­applications where high efficiency and low costs are important. The membrane stage is ­exchanged with the aid of a special replacement kit which ensures contact-free handling, thus ensuring GMP-compliant operation of the system.
