Abstract

A continuous deionization (CDI) module was constructed with all intermembrane spaces filled with mixed bed ion exchange resins, and was operated under polarity reversal conditions. The system was operated on feeds with and without scale-forming components as a function of the frequency of polarity reversal and applied voltage. Conductivity and pH profiles along the module and water quality obtained from the system were monitored and analyzed, based on water splitting and ion transfer throughout the system. Sensitivity to scale and recommended operating conditions are discussed.
