Electro-deionizationwater purification system for Power Generation, Pharmaceutical, Semiconductor 25GP~200GPM
The Electro-Deionization process is the latest technology in deionized water treatment to achieve ultrapure water.
EDI uses ion exchange resins in the presence of a DC voltage potential to remove cation and anion contaminants from the feed water supply. Ion selective membranes are then used within the modules to continuously remove these contaminants and carry them out in a small concentrate stream.
The voltage applied across the cell allows for the electrochemical "splitting" of water into hydrogen (H+) and hydroxide (OH-) ions within the ion exchange resins resulting in constant regeneration without the addition of chemicals, wastewater neutralization/disposal, and shutdown time. This results in a major advantage over the operation of traditional, regenerable Mixed-Bed Deionization and Service Exchange DI Systems.
The following are just a few of the industrial applications that
can benefit from purified water produced by EDI systems:
• Power Generation
• Chemical Manufacturing
• Electronics / Semiconductor
• Industrial Process Water
• Boiler Feed
• Research Lab Facilities
Operating Parameters
• Nominal Recovery: 90–95%
• EDI Water Quality: 15–18 meg-ohm
• Feedwater Requirements: See table on reverse side
• Operating Temperature: 50–100° F
• Maximum Inlet Pressure: 100 psig
• Minimum Inlet Pressure: 60 psig
• Expected Pressure Drop: 30–40 psig
• Electrical Requirement: 460 VAC, 3-phase, 60 Hz. 120 VAC, 1-phase, 60 Hz.
