Abstract

The integration of capacitive deionization cells is shown to deionize a secondary salt stream using solely the energy stored in a charged CDI cell. A primary cell was charged at 1.2 and 1.5 V resulting in electrosorption capacities of 3.3 and 3.7 mg NaCl (g carbon)-1, respectively. The cell charged at 1.2 and 1.5 V was used to directly deionize a parallel secondary stream resulting in electrosorption capacities of 0.5 and 1.0 mg NaCl (g carbon)- 1, respectively. Integration of CDI cells can drastically lower the energy cost for the production of fresh water.
