Evoqua IONPURE® IP-LX8000Z-5 High-Capacity CEDI Module for Power Plant Ultrapure Water Systems

The Evoqua IONPURE® IP-LX8000Z-5 is a high-capacity industrial continuous electrodeionization (CEDI) module specifically engineered to meet the large-scale ultrapure water demands of the power plant industry. As a flagship product in Evoqua’s IONPURE® lineup, it integrates advanced ion exchange resin technology and electrochemical separation principles, delivering consistent, high-quality ultrapure water while eliminating the need for chemical regeneration—making it a reliable and sustainable solution for critical power generation water treatment processes.

Core Process

The Evoqua IONPURE® IP-LX8000Z-5 operates on the proven CEDI principle, optimized for power plant feedwater conditions through three key stages:

1. Pretreatment Alignment: It accepts pre-treated feedwater (typically from reverse osmosis systems) with total dissolved solids (TDS) ≤ 50 ppm, seamlessly fitting into standard power plant water treatment workflows.

2. Continuous Ion Removal: Inside the module, ion-exchange resins capture dissolved impurities (e.g., calcium, magnesium, chloride, sodium), while a low-voltage electric field drives trapped ions toward respective electrodes. This prevents resin exhaustion, enabling 24/7 uninterrupted operation.

3. Ultrapure Output: The module consistently produces water with resistivity up to 18.2 MΩ·cm, meeting the strict purity requirements for power plant applications.

Key Specifications

Power Plant Applications

The Evoqua IONPURE® IP-LX8000Z-5 plays a critical role in power generation, supporting:

• Boiler Feedwater Treatment: Removes scale-forming and corrosive ions to protect boiler tubes, extend equipment lifespan, and prevent unplanned downtime.

• Turbine Cooling Systems: Supplies ultrapure water to maintain turbine efficiency by avoiding mineral deposits on heat exchange surfaces.

• Auxiliary Power Processes: Provides high-purity water for steam generation, chemical dosing systems, and flue gas desulfurization (FGD) processes.

Competitive Advantages

1. Chemical-Free Operation: Eliminates hazardous chemical regeneration, reducing environmental impact and operational safety risks—aligning with power plants’ sustainability goals.

2. High Capacity & Reliability: Designed for large-scale water production, ensuring consistent performance even under fluctuating feedwater conditions, critical for continuous power generation.

3. Cost Efficiency: Lowers long-term operational costs by cutting chemical procurement, waste disposal, and resin replacement expenses compared to traditional ion exchange systems.

4. Easy Integration: Compatible with existing power plant water treatment setups, minimizing retrofitting time and costs.

For power plants seeking a high-capacity, eco-friendly, and cost-effective ultrapure water solution, the Evoqua IONPURE® IP-LX8000Z-5 stands as an industry-leading choice, combining Evoqua’s decades of water treatment expertise with tailored design for power sector demands.
