Naturally present in mixers and faucets, biofilm is a collection of microorganisms (bacteria, algae, fungi, etc.) that adhere to each other and to surfaces that are generally in contact with water. It is characterized by the secretion of a protective and adhesive matrix (slime).
99.5% of bacteria found in these installations are trapped in the biofilm, which provides the ideal environment for them to develop - water, temperature and nutrients.
In good conditions the bacteria multiply and form aggregates that can easily become detached and contaminate the water supply.
Biofilm is impossible to eradicate. However, its development must nevertheless be controlled.
