Drinking water hygiene
Everyday, but not self-evident.


Drinking water is not 100% free of microorganisms. Pathogens (legionella, pseudomonads, E. coli) can also be present in cold water in low concentrations. This is harmless to health until these microorganisms multiply beyond a critical limit.

Even before the first drinking water pipes are installed, there is a lot that can be done for hygiene. By designing the installation in such a way that it provides neither food nor living conditions for microorganisms. But even if a drinking water installation has been perfectly planned and professionally commissioned, there is always a risk of recontamination. This is where our products come into play.

Shock disinfection

concentrated against germs

Even if a drinking water installation has been perfectly planned and professionally commissioned – there is always the risk of recontamination. Especially if the system is not operated as intended. In such a case, shock disinfection may become necessary. This means: the discontinuous addition of a disinfectant in high concentration. Chlorine dioxide has proven to be the best solution.

UV disinfection

Disinfects safely. Without chemicals.

The UV disinfection, eg. according to german DVGW worksheet W 293 and W 294, disinfects safely without the addition of chemicals and without changing the water composition. A prerequisite for effective treatment is clear water with low absorption in the relevant UV range. Therefore, prior treatment measures are usually necessary.
