Demineralized water, also known as deionized water, is a purified form of water that has had all its mineral ions removed, resulting in an ultra-pure, clear, and colorless liquid. The demineralization process involves removing minerals and salts, such as calcium, magnesium, sodium, and various metals, through a series of ion exchange and filtration techniques. This ensures the water’s high level of purity, making it ideal for a wide range of applications.
