  • Electrodeionization (EDI) - Home | DuPont

    2021-7-23 · 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).Using electrodeionization eliminates the need to store and handle the hazardous chemicals used for resin regeneration in mixed beds. And since electricity is EDI’s only consumable, this method of permeate polishing does not …

  • Ultrapure water by electrodeionization | Condorchem

    2021-7-23 · Reverse Osmosis Water System 1. How RO Works RO system uses strong pressure gradient to drive water through the semi-permeable membrane while removing impurities, thus leaving water purified. The system uses water line valve, which fits onto the cold water supply line. This valve has a tube which attaches to inlet RO pre-filter side. This is the water source of the RO system.

  • What's the difference between RO and DI water

    Although EDI can provide highly purified product water, the specific energy consumption (SEC) of EDI processes (0.39–2.11 kWh/m 3) is relatively higher than that of CDI processes (0.02–0.22 kWh/m 3) depending on the applied voltage, flow rate, and feed TDS concentration.

  • 5 Major Difference between RO and EDI Water

    2018-4-1 · Combination of two or more methods is the only choice to reduce these species at ultrapure water grade level. EDI itself is a combination of ED and mixed or layered bed ion exchange methods. Due to EDI feed water requirements, a pre-treatment step prior to EDI is necessary. In most cases, a single RO pass before EDI is enough to achieve this task.
