EDI

The FFM-EDI Series Electrodeionization Modules with advanced core components designed for high-purity water production, widely used in industries with stringent water quality requirements such as semiconductors, photovoltaics, power generation, pharmaceuticals, and laboratories. The series adopts a modular design, integrating ion exchange resins and selective ion exchange membranes. Combined with a DC electric field, it enables continuous ion removal and in-situ resin regeneration without chemical regeneration, achieving green, environmental friendly, and continuous operation.

Performance Features

• Continuous High-Purity Water Production: Ensures stable water output quality, superior to traditional mixed bed ion exchange processes.
• Premium Ion Exchange Resin: Utilizes high-performance resin to guarantee consistent product water quality and extended operational cycles.
• Wide Operating Range: Capable of stable operation under varying feed water quality conditions.
• Low Maintenance & Operational Cost: Simple maintenance procedures significantly reduce downtime and labor costs. No chemical regeneration required.

Critical Operating Instructions

• Thermal Management: Heat is generated when current passes through the EDI stack. Continuous water flow is required to dissipate this heat. Power must be immediately cut off if Dilute ,Concentrate, or Electrode Water flow is obstructed or stops to prevent stack burnout.
• Power Supply Requirements: The stack operating voltage is determined by internal resistance and optimal current. A stabilized DC power supply with a ripple factor ≤ 5% is mandatory.
• Chemical Cleaning: If external cleaning of the membrane stack is required, use a mild cleaning solution only. Never use solvents. Ensure power is disconnected before cleaning.
