Centralised softening of drinking water
In the last years centralised softening of drinking water is increasingly being discussed and realised - in particular in areas with a high hardness level…
Deacidification
Excess carbonic acid (carbon dioxide) often occurs in natural groundwater or spring water. This water is referred to as acidic water. Contents of up to 100 mg/l CO2 are…
Arsenic removal
In addition to iron and manganese, arsenic is another trace substance that occurs especially in reduced groundwater (deep water). Arsenic contamination of drinking water occurs…
Demanganization
Manganese can be removed almost completely from water through demanganisation. Manganese often occurs in water along with iron. Water containing manganese is generally…
Iron removal
Water with an increased iron content (> 0.2 mg / l) must be treated. Water containing iron is generally reduced-oxygen or low-oxygen water in which the iron is usually present…
Ozone bio-filtration
The natural organic matter (NOM) content is significant if the water is to be used for the drinking water supply. The NOM concentration is recorded analytically as the sum of…
