The Evoqua IonPure IP-LXM45Z-4 is a high-performance industrial electrodeionization (EDI) module engineered specifically to meet the rigorous ultrapure water requirements of the power plant industry. As a flagship product in Evoqua’s IonPure lineup, it integrates advanced ion exchange and electrochemical technologies to deliver consistent, high-quality water, eliminating the need for frequent chemical regeneration associated with traditional ion exchange systems—making it a reliable choice for critical power generation processes.
Core Process
The Evoqua IonPure IP-LXM45Z-4 operates on the continuous electrodeionization (CEDI) principle, a three-stage process optimized for power plant applications:
Pretreatment Integration: It accepts pre-treated feedwater (typically from reverse osmosis systems) with low total dissolved solids (TDS), ensuring compatibility with power plant water pretreatment workflows.
Ion Removal: Inside the module, ion-exchange resins trap dissolved ions (e.g., sodium, calcium, chloride) while an electric field drives ions toward respective electrodes, preventing resin exhaustion and enabling continuous operation.
Ultrapure Water Production: The output meets power plant standards, with resistivity reaching up to 18.2 MΩ·cm, critical for boiler feedwater, turbine cooling, and other high-purity applications.
