Comprehensive guide to Capacitive Deionisation technology, electrosorption principles, cell architectures, and advantages for cost-effective brackish water treatment and desalination.

Capacitive Deionization (CDI) for Desalination: How It Works and When to Use It Capacitive deionization (CDI) is an emerging electrochemical water treatment technology that removes dissolved ions from water using porous carbon electrodes. Unlike reverse osmosis which uses pressure to push water through a membrane, CDI uses an electric field to attract and hold ions on the surface of electrodes. This makes CDI particularly energy-efficient for treating low-to-moderate salinity

The performance characteristics of electrodeionisation systems are fundamentally determined by two critical material components: the ion-selective membranes that enable directional ion transport, and the ion-exchange resins that capture and release dissolved ions under electrical control. Understanding how these materials work, how they're manufactured, and how they're engineered to perform under the extreme conditions of modern water treatment provides insight into why EDI t

Electrodeionisation (EDI) represents a fundamental departure from traditional ion-exchange water treatment approaches that have dominated the industry for decades. While conventional ion-exchange systems require periodic chemical regeneration with caustic and acidic solutions, EDI employs continuous electrochemical regeneration powered by a low-voltage electrical current. This distinction is more than academic; it translates to transformative advantages in operational efficie
