HEED® Current Utilization Efficiency

Current utilization efficiencies should be >70% for efficient use of ED for desalting typical brackish water feeds, and current utilization decreases as the product water concentration decreases. The following graph shows that HEED® provides excellent current utilization efficiencies (>90%) over a wide range of product water concentrations. The graph also
shows that good current utilizations are achieved even when producing high quality product
(<5 mg/L Cl-).
