Ozone disinfection

Ozone disinfection for products, process water, and equipment

Safe food starts with safe hygiene.

Why disinfection is more important today than ever before – results of the HAW study 2025

The current study “Analysis of the microbiological condition of ready-to-eat salads in food retail” (HAW Hamburg, 2025) clearly shows the challenges facing the fresh-cut and vegetable industry:

30 samples of ready-to-eat salads were examined.
High total bacterial counts already several days before the best-before date.
Over 50% of the samples showed abnormal
Enterobacteriaceae values.
E. coli was positive in isolated cases.
Listeria & salmonella were not found – but the study expressly warns:
Even small temperature deviations cause listeria to grow rapidly in fresh-cut products.

Key message of the study:

👉 A significant proportion of salads show microbiological abnormalities even before the best-before date is reached.

For businesses, this means:
Process hygiene and product disinfection must be significantly improved if safe products and better shelf life are to be achieved.

This is exactly where ozone comes in.

Ozone as a solution – one device, three applications

Our universal ozone module turns normal service water into a highly effective disinfectant.

This allows products, process water, and systems to be operated hygienically at the same time – without leaving any residue, economically, and completely free of chemicals.

1. Product disinfection – fewer germs, better shelf life

Ozone water reliably reduces germs, yeasts, and spores.

In a partner company, we were able to reduce the yeast concentration by around 70%.

2. Process water disinfection – clean water in the cycle

Ozone turns your process water into an active disinfectant.

3. Equipment disinfection – cleaning during production

Ozone water can be used to disinfect equipment automatically and continuously.

Why ozone? – The most important advantages at a glance

Effective against bacteria, yeast, spores, and biofilms
Decomposes into pure oxygen without leaving any residue

Lower process costs
Significant improvement in hygiene, quality, and shelf life

Conclusion: Safe products start with the process

The HAW study clearly shows that even commercially available salads often have critical germ counts. With our ozone module, water becomes a disinfectant, and you get:

Clean products
Clean process water
Clean systems
All with just one device, highly effective and economical.
