Hebei Huayu Environmental Engineering Co., Ltd presents the Pureflow EDI Industrial Water Treatment System, engineered to deliver continuous deionized water without the need for chemical regenerants. By integrating electrodeionization modules with upstream pretreatment units, this system reliably produces water with resistivity exceeding 15 MΩ·cm for applications in power generation, electronics manufacturing, and laboratory processes.
System Architecture and Components
Feed-Water Conditioning: Raw or RO-treated water enters a multimedia filter and activated-carbon stage to remove particulates, chlorine, and organic compounds, protecting downstream membranes and resin beds.
EDI Module: Multiple EDI stacks comprise alternating cation- and anion-exchange compartments separated by ion-selective membranes. When an electric field is applied, ions migrate through membranes into concentrate channels, regenerating the resin beds continuously.
Control Panel and Monitoring: A PLC-based control unit monitors key parameters—conductivity, resistivity, flow rate, and voltage—and adjusts feed-pump speed and electrical current to maintain target purity and energy efficiency.
Concentrate Handling: Concentrated ion streams are directed to drain or further treated, complying with local discharge regulations.
Performance Features
Continuous Regeneration: Eliminates downtime and chemical handling associated with conventional ion-exchange systems.
Stable Output Quality: Real-time sensors and feedback control maintain consistent water quality even with fluctuating feed-water conditions.
Modular Design: Skid-mounted units allow easy expansion by adding additional EDI modules in parallel.
Materials and Construction
All wetted components use corrosion-resistant plastics or SS316 to prevent leaching of impurities. Electrical enclosures meet IP65 protection, and high-purity piping employs electro-polished stainless steel. The system complies with ISO 9001 for quality management and relevant IEC safety standards.
Applications and Benefits
The Pureflow EDI system supports boiler-feed pretreatment in power plants, ultrapure-water loops in semiconductor fabs, and reagent-grade water supply in analytical laboratories. Continuous operation reduces operational costs by eliminating acid and caustic regenerants, while automated monitoring and alarm functions minimize manual intervention.
