Biofilms Biofilms consist of bacteria, algae, fungi and protozoa. The mucus layers can be seen with the naked eye and consist of up to 10,000,000,000 germs/ml. Once nested in a system, biofilms are difficult to combat because the biopolymers act as a protective coating against most disinfectants.

Contamination in test benches Contaminated test stations can permanently and sometimes irreversibly contaminate entire production batches, particularly if contaminated water is forced into the parts under pressure.

Biofilms and VBNC
In case of extensive biofilm growth, disinfection with chlorine is practically useless, since the biofilms are not effectively removed. In addition, the bacteria are often in a "VBNC" state. (Viable But Not Culturable). This skews performance controls and offers a false sense of security.
In contrast, Sanosil can effectively eliminate both biofilms and VBNC germs.

•
After 14 days, reduce to 0.1%
•
Seal components to prevent germs from entering from the outside
