5000L EDI Stacks EDI Modular Electrodeionization
This EDI Modular with capacity of 5000LPH is a continuous, chemical-free process of removing ionized and ionizable species from feedwater using DC Power to provide ultrapure water that the resisitivity above 15 MΩ.cm, apply for pharmaceutical , biotechnology, electronic conductor industries and so on. EDI is typically used to polish reverse Osmosis (RO ) permeate, and is a smart alternative to- and effective replacement of- conventional mixed bed ion exchange(IX).
