Disinfection using water

COFRAC certified laboratory tests

The performance of Olimpe’s in-line electrolysis technology is attested by the analyses carried out by the QUALYSE laboratories, whose processes are regularly monitored by COFRAC (the French Accreditation Committee) and who conform to a highly rigorous standard of precision.

The analyses presented here were carried out at the request of one of our clients. This is a supermarket that wanted to verify that the disinfection levels achieved with Olimpe in its butchery were comparable to those achieved with traditional disinfectants. A test protocol was therefore drawn up in order to carry out microbiological sampling and analysis in a real situation for each disinfection process used.

Disinfected surfaces

Floors and worktops in the butchery area

Sampling methods

Contact tabs
Wipes

Pathogens tested for

  • Coliform bacteria
  • Mould
  • Aspergillus
  • Staphylococci

The analyses carried out demonstrate the effectiveness of Olimpe:

✓ Drastic decrease in total flora of treated surfaces
✓ Total absence of pathogens of interest
✓ Better level of disinfection than with the traditional process
