Integrated Capacitive Deionization and Humidification-Dehumidification System for Brackish Water Desalination

A hybrid capacitive deionization and humidification-dehumidification (CDI–HDH) desalination system is theoretically investigated for the desalination of brackish water. The CDI system works with two basic operations: adsorption and regeneration. During adsorption, water is desalted, and during the r...
