Ozone, a fantastic solution for Surface Sanitation

If you are looking for surface sanitation solutions, Ozone is your answer! One of the several properties of Ozone is the strong oxidizing agent. Because of that, Ozone is the best option when it comes to surface sanitation, whether it is in food safety sanitation, ozone applied to water or pool sanitation, or in countertops in our daily lives or food processing industry, Ozone comes as a great sanitation solution.

Adopting ozone in cleaning and disinfection process can bring many advantages over commonly disinfectants. Ozone can be one of the most effective sterilizing tools.

Ozone is the most powerful oxidative agent that occurs naturally. It is able to destroy germs, virus, bacteria and microbes that may cause surface or air contaminations. Furthermore, ozone leaves no chemical residue typical of alternative detergent or synthetic cleaners because it breaks down quickly into oxygen. However, it must to be handled properly.

It is a strong disinfectant and it is increasingly used for infection protection and multiple sterilization applications: to sanitize laboratory tools, especially ones involved in sensitive experiments; It is effective to sterilize pipettes, gloves, plates, small equipment and even personal items such as keys and glasses. Also, surfaces, such as floors, walls, counter tops, conveyer belts, fruit bins, crushers, pipes can be sanitized with direct application of ozone and water.

How does it work?

Ozone is able to kill 99.7% of 650 different kinds of pathogenic organisms (bacteria and fungi) and it is very safe and efficient. It can penetrate cavities or crevices that normally are hard to clean and no rinse is needed after ozone application, as ozone will leave no residual on the surface. This may lower cleaning time and water usage costs.

Because ozone requires no storage or special handling and does not need to be mixed with other products, it may be viewed as advantageous over other chemical sanitizers. Also, ozone is used for surface sanitation in many food processing applications, because it is a powerful oxidant that kills all bacteria on contact.

In food processing it is essential to keep food products pathogen free and reduce the potential for cross-contamination of deadly pathogens. Therefore, the surface sanitation is very important. One of the major concerns for cross-contamination on food processing equipment is biofilm build-up.

Biofilms are layers of microorganisms that grow up tightly in the surfaces. What happens is the new layer of microbes can provide nutrients and protection against sanitizers, and it is a concern because over time it makes sanitation more difficult. These resistant biofilms are most common in cracks, crevices, conveyors, knives, slicers, and portioners and corners of food processing equipment that are only sanitized periodically.

Because of the strong disinfection power of ozone, the biofilm can be removed by ozonating over an extended time period, allowing ozone to break down cell walls and organic material and prevent future growth.
