Naturally present in mixers and taps, biofilm is a collection of microorganisms (bacteria, algae, fungi, etc.) adhering to each other and to surfaces that are generally in contact with water, and which is characterised 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 (water, temperature and nutrients) for them to develop.
If the conditions are favourable, 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.
