EDI Technology
With anion cation ionexchange membrane,ion exchange resin,and DC electric to implement ions directed migration.thus completing water desalination. meanwhile resion regenerate with H and OH from electrolysed water,so no chemical is needed.
How EDI works
1. Evenly assignwater to the freshwater room, RO enters the EDI module.
2. The trace ions with RO membrane are adsorbed on the membrane surface.
3. DC is added to the EDI module at both ends of electrodes to drive the fresh water chamber of the cationanion to the corresponding electrode moving to the dense water chamber.Then the water with high purity is obtained.
4. Driven by the effects of electric field, a large number of water molecules are ionized into H+ and OH- , thus regeneration can be continuously kept
