Why does unstable RO permeate affect EDI performance?

Unstable RO permeate directly affects EDI performance due to fluctuations in feedwater quality, which disrupts the ion exchange and current balance within the EDI module.

This issue typically arises when the conductivity or ion concentration of the RO permeate varies significantly. Key factors include inconsistent RO membrane rejection rates, improper chemical dosing upstream, or changes in source water conditions. To diagnose this problem, check the stability of your RO system's output parameters such as conductivity (ideally below 10 μS/cm), pH levels, and temperature.

For optimal performance, ensure that:

• The RO system is properly maintained with regular cleaning schedules.
• Feedwater pretreatment aligns with the specific requirements of your water treatment line (e.g., dual-stage RO for purified water applications).
• There are no significant pressure drops across the RO membranes.

Next steps include reviewing your entire water treatment workflow, from raw water intake to final polishing stages.
