Electrodeionization (EDI) plant
Berkefeld Filter

ELGA Berkefeld EDI plants are suitable for the full desalination of low salt level water which has already been treated in a reverse osmosis plant. Depending on the plants' levels and the cell design conductivity values in the deionate from
0,055 μS/cm to 0,5 μS/cm are attainable.
By using a three-chamber-system with the electrodes arranged in a resin bed a simultaneous reduction of germs and a lowering of organic carbon can be attained, without even needing a UV plant in the deionate range.
ELGA Berkefeld electro-deionisation plants (EDI) are available in a great diversity of models. In a performance range of up to 300 l/h as combination appliances together with a reverse osmosis type midiCEDI, from 500 l/h up to 3000 l/h and beyond as cupboard plants and plants on stands, type CEDI LX.
