Ozone Water Sterilization Unit

The markets has an increasing demand for fruits, vegetables and salads clean of any contamination from pathogens and chemical contaminants or detergents.
Ozonized water is used in a variety of operations to wash fruits and vegetables including ready to eat salad products.
Ozone is a more powerful disinfectant than Hydrogen Peroxide, chlorine, chlorine dioxide and many of the industry disinfectant agents. Ozone is effective against an Extremely wide range of pathogens .
Ozone is said to be about 50% more powerful and to act 3,000 times faster than chlorine at 100 times the strength.
More to add, in the water, ozone has a lifespan of 10 to 20 minutes only, after which it breaks down to oxygen. Therefore the Ozone does not leave any harmful byproducts as other disinfectors do. This prevents contamination of the products with any byproducts pollution and also allows easy discharge of the used wash water.

Ozone destroys all molds, viruses and bacteria common in the food industry:
