DI (deionization) resin is used to remove ions from water, effectively purifying it by replacing unwanted cations and anions with hydrogen and hydroxide ions, respectively. This process results in deionized water, which is highly pure and free from dissolved mineral salts, making it ideal for laboratory, industrial, and cleaning applications where water purity is critical. DI resin is typically used in conjunction with other filtration systems to achieve the desired level of water purity.
