Filtration via activated carbon
Filtration via activated carbon is generally not used in water treatment for solids and particle separation. The main use of activated carbon is the adsorption of…
Filtration
The methods of filtration used for water treatment vary greatly. Filtration includes all processes that mechanically separates a mixture of liquid and solid or dissolved substances into…
Oxygen enrichment
Oxygen is the most important oxidation agent in the context of water treatment. In addition, a sufficient oxygen content is relevant for the drinking water quality and for the…
Radioactive and anthropogenic substances
Naturally radioactive substances (radon, uranium) as well as anthropogenic substances such as pharmaceuticals, fertilisers and pesticides as well as…
Nanofiltration and Reverse osmosis (RO)
Reverse osmosis is a pressure-driven physical process for separating liquids and substances dissolved in them. They are used in particular at saltwater…
Membrane processes
The following processes are grouped together under membrane processes:
Microfiltration (MF) Ultrafiltration (UF) Nanofiltration (NF) Reverse osmosis (RO)

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…
