■ Technical Overview

The core of this innovation is the Electrodialysis Reversal(EDR)technology, which utilizes a direct current electric field to drive the migration of ions through selective ionexchange membranes, effectively separating dissolved salts into concentrate and dilute streams. Through periodic polarity reversal and internal flow redirection, the system performs self-cleaning of membrane surfaces, preventing scale formation, enhancing operational stability, and extending membrane lifespan. By integrating EDR into cooling water management, the solution achieves :

  ▶ Reduced cooling tower makeup water demand.

  ▶ Lower total water consumption and wastewater discharge.

  ▶ Decreased chemical usageand operating costs.

  ▶ Improved water reuse efficiency and energy efficiency.

 

■ Feature

  ▶ Modular Design.

  ▶ Polarity Reversal Mechanism.

  ▶ High-Selectivity Ion Removal.

  ▶ Low Operating Pressure.

  ▶ Multi-Water Quality Compatibility.
