This study examined the newly developed process of Capacitive deionization (CDI) for
removing ions through their adsorption on the surface of two oppositely charged porous
electrodes. This electrochemical process is conducted at low voltage (typically 0.8-1.5 V)
without high-pressure pumps and acts as a "flow-through" capacitor. Theoretical
aspects to CDI and basic electrochemical principles have already been described.
The general purpose of this study was to determine the feasibility and performance of
electrochemical removal of total dissolved solids (TDS), nitrate and ammonia by using proprietary charge-barrier
CDI technology (ENPAR Tech. Inc.). Optimal operation conditions, salts removal
rates and power consumption were determined for various influent TDS concentrations. Materials and methods discussed in the study include: electrode material; the DesEL 9K pilot plan; system description; experimental setup; and, design of experiments. Includes 6 references, tables, figures.
