Ion exchangers for drinking water treatment

Limescale deposits caused by drinking water

Drinking water undergoes extensive water treatment processes. It is strictly controlled and supplied as a clear, colourless liquid.

It is free from unpleasant odours and harmful substances. However, it is enriched with essential minerals and salts. This water quality is suitable for food, but not necessarily for technical applications.

Drinking water is not always suitable for technical applications and can cause problems such as limescale deposits on heat exchangers. Water used in technical applications, such as boiler feed water, heating water or process and service water, usually comes from the public drinking water supply. Alternatively, it is extracted from wells, rivers and lakes.

Removal of electrical charge carriers (ions)

from drinking water

Minerals, salts and carbonic acid dissolve in drinking water as electrical charge carriers, known as ions. These give drinking water properties such as electrical conductivity, total hardness and pH value. The solubility of these substances depends largely on the amount of water, temperature and application. It influences the technical usability of the water.

Drinking water can be specifically treated using ion exchangers. The electrical charge carriers dissolved in the water are removed or exchanged. This makes the water suitable for the respective application.
