GENO®-EDI-X systems function as a process step for residual demineralisation (polisher) after GENO®-OSMO reverse osmosis. Conductivity of up to 0.055 µS/cm can be achieved. Electrodeionisation (EDI) is an electrochemical demineralisation and process technology combination of electrodialysis and ion exchanger. The EDI module consists of ion-selective membranes and regenerative ion exchange resins, which are sandwiched between two electrodes. DC voltage applied at the poles forces the ions to migrate according to how they are charged. The result of the process is demineralised water. The various EDI system modules offer maximum diluate capacities of 100 l/h to 2.700 l/h.
The installation site must offer adequate space. Around the system, there must be adequate space for installation and service work (> 50 cm, or > 20 cm to the wall). Provision must be made for sufficiently large and durable foundations. The required connections must be provided prior to the installation work. The installation of an electrodeionisation system represents a major intervention in the drinking water system. Therefore, only authorised experts may install such systems.
