Demineralization treatment of water removes dissolved minerals and salts from the water by producing high purity water ready for industrial, pharmaceutical, and laboratory use. The general steps involved in the process are ion exchange, where water is made to pass through resin beds, exchanging the unwanted cations and anions such as calcium, magnesium, and sulfates for hydrogen and hydroxide ions. This system is crucial in applications that involve water with low conductivity and a little amount of dissolved solids to ensure reliability and efficiency of sensitive equipment and processes.
