Electrodialysis Reversing Rectifier Introduction

This 100A 300V electrodialysis automatic reversing rectifier delivers specialized DC power with intelligent polarity switching for membrane-based separation processes. Consequently, it enables continuous and efficient desalination by automatically reversing ion migration directions, which significantly reduces membrane scaling and fouling.

Technical Specifications

Key Features

• Automatic Polarity Reversal (EDR): This electrodialysis rectifier performs scheduled polarity reversals automatically. Therefore, it effectively dissolves scale precursors on membrane surfaces before they solidify, ensuring stable system performance and reducing chemical cleaning frequency.
• Optimized for Membrane Protection: Features like soft current ramp-up and a dedicated membrane protection mode prevent hydraulic and electrical shocks to delicate membrane stacks. As a result, membrane lifespan is extended, and operational reliability is significantly improved.
• High Voltage for High Resistivity Waters: The 300V output range enables operation with low-conductivity feed waters or high-resistance stacks. Moreover, this ensures sufficient driving force for ion migration even in advanced purification stages or ZLD applications.
• Process Integration & Control: With built-in ED process presets and remote I/O ports, the rectifier seamlessly integrates with overall plant control systems. Furthermore, operators can monitor and adjust key parameters in real-time for optimized desalination efficiency.

Applications & Advantages

This specialized reversing rectifier is critical for modern membrane-based water treatment and resource recovery.

In High-Purity Water Production for electronics and pharmaceuticals, it powers EDI systems to remove ionized impurities. Importantly, the automatic reversal function maintains consistent product water quality without chemical regeneration.

For Brackish Water Desalination, it drives ED systems to produce potable or process water. Additionally, the EDR process significantly reduces operational costs by minimizing antiscalant usage and membrane replacement frequency.

In Industrial Wastewater Reuse & ZLD Systems, it enables selective salt concentration and recovery. Ultimately, this supports sustainable water management by turning waste streams into reusable resources.

Finally, this 100A 300V rectifier is not just a power supply but a core process optimizer for electrodialysis technology. For this reason, it delivers exceptional operational stability, reduced maintenance, and superior cost-efficiency in advanced water treatment applications.
