Abstract

The demineralization process of water using ion exchange resin is widely applied in the water treatment industry to produce pure water. However, the performance of ion exchange resin tends to decrease over time due to the accumulation of ions adsorbed on its surface. Therefore, resin regeneration is important to restore the resin's ability in the demineralization process. This study aims to optimize the regeneration method of aqua-demineralization resin using a combination of NaOH and HCl as regeneration materials. The variables tested include the concentration of NaOH and HCl solutions and the contact duration. The results of this study indicate that the combination of NaOH and HCl can increase the regeneration efficiency of aqua-demineralization resin, with optimal conditions at a concentration of 4% NaOH and 4% HCl, and regeneration duration of 30 minutes.
