Abstract
In this study, removal of hardness from water using a capacitive deionization system with activated carbon cloth electrodes was investigated. The dynamic study indicated that the hardness removal process followed the pseudo-first-order kinetics model and more than 90 % of the hardness ions could be removed during the first 0.5 h of the electrosorption process. Two types of regeneration methods were compared and the results showed that compared reversing electrodes' polarities, the regenerating method of short circuit of electrodes was more effective for activated carbon cloth electrodes regeneration. The hardness removal performance of activated carbon cloth electrodes could remain stable after five consecutive cycles of electrosorption/regeneration.
