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 laid, there is a lot that can be done for hygiene. By designing the installation in such a way that it provides neither food nor livelihood 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.
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, disinfection of the stand may become necessary. This means: the discontinuous addition of a disinfectant in high concentration. Chlorine dioxide has proven to be the best solution.
If a drinking water system is contaminated with germs and neither operational nor constructional measures to eliminate their cause are possible, continuous drinking water disinfection according to german DVGW worksheet W 557 can be helpful. Chlorine dioxide is expressly included among the approved agents according to § 11 of the drinking water ordinance.
The UV disinfection according to german DVGW worksheet W 293 and W 294 disinfects safely without the addition of chemicals and without changing the water contents. A prerequisite for effective treatment is clear water with low absorption in the relevant UV range. Therefore, previous treatment measures are usually necessary. DVGW- or ÖNORM-tested UV disinfection systems must be used to produce drinking water quality.
