Ozone Sanitation vs. Conventional

U.S. Environmental Protection Agency

Historically, chlorine, hot water and steam have been the sanitizer of choice in the food and beverage industry. But experts have long shared a growing concern about dangerous chemical by-products, trihalomethanes (THM) or dioxins, produced when chlorine reacts with the organic matter found in water. These by-products are known carcinogens and when found in drinking water their levels are strictly regulated by the U.S. Environmental Protection Agency (EPA). Additionally, companies are looking for ways to cut costs and the elimination of hot water and steam are huge savings.

When ozone reacts with organic matter, it does NOT form any toxic by-products. In fact, the water in which ozone is delivered can be filtered and even reusedóreducing the amount of water a plant utilizes. Since ozone is mixed with cold water energy savings are quickly realized.

  • Ozone does not leave toxic by-products similar to those related to chlorination
  • Ozone kills bacteria 3000 times faster than chlorine ozone
  • Ozone 51% more powerful on bacterial cell walls than chlorine

Since ozone is so highly reactive, it is also effective in controlling and removing films that sometime form on processing equipment. Ozone is an effective way of reducing biological oxygen demand (BOD), chemical oxygen demand (COD) and turbidity or other residues left in water.

Chlorinated wash systems require transport and storage of potentially hazardous, toxic chemicals. Ozone is generated on site and is produced on demand with no storage requirements. When an ozone generator is turned off, there are no dangerous substances left on the premises.

Employee working conditions are a major concern for environmental agencies and worker safety organizations. Using ozone eliminates the need to handle, mix and dispose of harsh chemicals. Overexposure to chemicals has been linked to various diseases and conditions, especially in association with the lungs and throat. No one has ever died as a result of exposure to ozone. OSHA has a maximum acceptable concentration limit for ozone, but the risks of over-exposure to ozone are limited to irritated skin and membranes. As a result, companies are able to lower their operating costs with regards to medical and liability insurance.
