5000L EDI Stacks EDI Modular Electrodeionization
This EDI Modular with capacity of 5000LPH is a continuous, chemical-free process of ion-exchange, removing ionized and ionizable species from feedwater using DC Power , the electrical regeneration to provide ultrapure water that the resisitivity above 15--18 MΩ.cm.

EDI Modular treatment Process:
Key Benefits of EDI Systems
Chemical-Free Operation: Eliminates the need to purchase, store, handle, and dispose of hazardous regeneration chemicals (acids and bases), improving safety and reducing environmental impact.
Continuous Operation: Provides a steady, on-demand supply of high-purity water without the downtime required for resin regeneration in conventional systems.
Consistent Water Quality: Continuously produces ultrapure water, typically with a resistivity of 15-18 MΩ·cm, which is stable and not subject to the purity decay seen in conventional mixed beds as they exhaust.
Low Operating Costs: While the initial capital cost may be higher, the elimination of chemical purchases and reduced maintenance often results in a lower total cost of ownership over time.
Space Efficiency: Modular EDI systems have a compact footprint compared to conventional ion exchange systems with separate chemical storage and regeneration machine
