Stainless Steel Electrodeionization Plant, Voltage : 220V

Listing ID #7174841

Electrodeionization (EDI) is used after reverse osmosis for polishing of demineralized water to obtain low levels of conductivity and silica. The EDI uses ion exchange membranes, ion exchange resins and electricity to produce high-quality water with no regeneration downtime. EDI is an alternative to a conventional mixed bed polisher. Electrodeionization System (RO EDI Plant) technique can achiever high purity of Deionized water with conductivity less than 0.1 μS/cm.
EDI advantages

• CONTINUOUS PROCESS : EDI provides a simple and continuous operation with no downtime due to the electrochemical regeneration.
• NO USE OF CHEMICALS : EDI utilizes chemical-free regeneration. Therefore, no storage or application of chemicals is required.
• SPACE-SAVING PLANTS : The EDI plants are space-saving due to the very compact design.

Typical Applications of EDI

• Water for power plant : Instead of using a conventional mixed bed, a membrane degasser in combination with EDI can produce high-quality demineralized water without using any chemicals. This provides corrosion-free boiler feedwater with low conductivity and silica content.
• Ultrapure process water : EDI after reverse osmosis supplies ultrapure process water with low conductivity. The photo shows EDI for ultrapure water at a microelectronic company. The EDI is customized with special pharma modules for a hygienic design.
• Water for pharma : Purified water production within pharma industries requires a water treatment system in a hygienic design. The EDI is customized to meet the current versions of Standards.
