Centralised softening of drinking water
The term "water hardness" primarily refers to the concentration of the alkaline earth metals magnesium (Mg) and calcium (Ca) dissolved in water. The higher…
Deacidification and Hardening
Drinking water must be corrosion-neutral in accordance with applicable regulations. The Drinking Water Ordinance specifies a pH range between 6.5 (slightly acidic) and…
Arsenic removal
In addition to iron and manganese, arsenic is another trace element that occurs particularly in reduced groundwater (deep groundwater). Arsenic contamination of drinking water is…
Demanganisation
The limit value for manganese in drinking water is 0.05 mg/l. This low value is not based on health considerations but primarily serves to protect the distribution network from…
Iron Removal
Drinking water with an iron content of more than 0.2 mg/l must be treated, even if iron does not pose an immediate health risk.
Iron impairs the sensory quality of drinking…
In view of the uncertain global political situation and ongoing economic challenges, many people are finding it increasingly difficult to focus on the future.
Ozonation in water treatment
Ozonation is an effective step in water treatment with a wide range of applications: drinking water and swimming pool water to aquaculture and wastewater treatment.…
Systems for drinking water treatment
Drinking water treatment is a matter of trust. Many people believe that the purpose of treatment is to turn poor water into good drinking water. Although this is…
Decarbonisation/Partial desalination
With softening, only the ions of the hardeners calcium and magnesium are exchanged. With decarbonisation, on the other hand, the hydrogen carbonate salts of the…
Activated carbon for water treatment
The primary use of activated carbon in water treatment is the removal of organic and specific inorganic substances from water by adsorption. Activated carbon…
