Cooling Tower Water Treatment Chemicals

Product Details:

The primary process with water treatment chemicals is softening, which is most commonly achieved via ion exchange. The ion-exchange principle is a type of treatment in which the dissolved salts Ca2+ (lime) and Mg2+ (magnesium) are removed from the water in order to reduce its hardness. During this process, drinking water is passed through special ion-exchange resins made from a type of plastic. The exchangers pick up dissolved ions with a specific charge and release a corresponding amount of different ions with the same charge. This means that lime and magnesium molecules are removed from the water because they are more strongly attracted to the binding sites on the ion-exchange materials, which, in turn, release the weakly binding molecules attached to the resins. Specifically, calcium and magnesium ions are exchanged with sodium ions, thereby softening the water. The ion-exchange resin must be treated and the entire system cleaned and disinfected regularly — otherwise, there is a high risk of microbial contamination and biofilm formation. Sanosil AG offers corresponding water treatment products for these tasks. Additional chemical water treatment takes place, for example, during iron removal/demanganization. In this process, air or hydrogen peroxide is added to the water and undesirable substances are removed via oxidation.
