Abstract

Demineralized water is water that has many uses. In laboratories, demineralized water is used as a solvent and for washing laboratory equipment, while in industry demineralized water is used as process water for BWF (Boiler Feed Water). The water demineralization process using ion exchange is one method of water purification process. Basically, the water purification process using the ion exchange method is to replace all cations and anions (other than OH-) dissolved in water with hydrogen cations and OHanions from the resin. Analysis of the efficiency of ion exchange resins in this research uses observation data on the conductivity of raw water with demineralized water products. The research results show that the efficiency values of cation and anion resins in the demineralization process are 72.86% and 82.05%, respectively. Other results also show that the length of the regeneration cycle in the demineralization process is 13 hours for continuous use. The efficiency value of the cation resin is below the standard, namely 80%, meaning that the cation resin is experiencing saturation and a decrease in quality. Meanwhile, for anion resin, the efficiency value obtained is >80%, indicating that the resin quality is classified as so good and not saturated.
