Abstract
This paper presents a novel method for making Capacitive De-Ionizatrion (CDI) water purification more efficient and cheaper, using a buck-boost DC-DC converter. The energy recovery is superior (51%) versus maximum reported results in the literature (30%) [1]. First, the concept of a CDI cell is introduced. Second, the existing methods for energy recovery are reported showing their advantages and disadvantages. Then, the novel method using a buck-boost converter is presented. Simulation results are provided. Experimental data verified the new technique and agrees with simulation.
