EDI – electrodeionization system for ultra pure water

October 2020

Italy

Electronic and semiconductors

Description:

Installation of a new electrodeionization system (EDI) for the production of ultra pure demineralized water for the electronic and semiconductors industry. This new plant was installed after a double pass RO system to substitute an ion exchanger with mixed bed resins, in order to reduce the waste effluents generated by the regeneration of the resins and improve the efficiency of the system.

Technical characteristics:
Flow-rate capacity of 10.000 lt/h
Output resistivity > 18 MOhm x cm
Minimum electrical power absorbed < 2 kW
Minimum discharge 5-6% reject

Highlights:
n°2 EDI cells
5% of water reject
Automatic functioning H24
