Water information

If water contains suspended particles or colloids, transparency is reduced. This is due to light scattering caused by these particles. Photometric turbidity measurement is used to determine the proportion of undissolved particles in the water sample.

Sodium is a vital element and occurs in practically all water. When ion exchangers are used to soften water, the hardness minerals calcium and magnesium are exchanged for sodium.

Aluminum dissolves from clay minerals in acidified soils and can thus enter well water. Another source is unsuitable sacrificial anodes in hot water tanks.

Our water can contain an exceedingly large number of organic, i.e. carbon-containing substances. These can be natural substances (e.g. humic acids, carbohydrates, amino acids), but also pollutants (e.g. wastewater, mineral oil, pesticides, cyanides).

The colony count is an indicator of the general microbiological load of the water without any further indication of the presence of pathogens.

79% of Legionella infections originate from the private environment. In summer and autumn, the number of infections increases leisure activities, climate conditions and water temperature.

Pseudomonas aeruginosa is a bacterium that typically resides in moist soil in the environment. It is very robust to environmental influences such as fluctuating temperature or drought.
