Dow Microbial Control, a business unit of The Dow Chemical Company, announced the launch of Advanced Oxidation System (AOS) Certified technology for whole room sanitization. This new, revolutionary advancement will provide food and beverage producers with an effective and environmentally sustainable system for controlling surface and airborne pathogens.  

AOS Certified systems fill an unmet need in the global food processing industry for a whole room sanitization technology that is designed to work quickly and safely to reduce dangerous bacteria such as Listeria monocytogenes, E. coli and Salmonella, which pose serious health risks to consumers and a great financial risk for food manufacturers.

Using ambient air to generate ozone and water to produce non-condensing humidity, AOS Certified technology fills the atmosphere with a sanitizing vapor that goes deep into every corner, rapidly penetrating hidden areas in equipment, drains, air conditioning vents and fabrics. The vapor then fully dissipates, leaving no condensation or residue, making it effective even in dry environments such as bakeries. Because the sanitizer is produced as needed, using AOS Certified technology does not involve shipping, storing or handling of chemicals.

“Dow Microbial Control is drawing on its core expertise in developing advanced, sustainable microbial control to provide a reliable sanitization solution for today’s food-processing companies,” said Bryan Kitchen, global business manager for Advanced Oxidation Systems, Dow Microbial Control. “AOS Certified technology leverages ozone’s unequalled microbial control to help customers maintain a pathogen-free environment that is easy to monitor, control, record and certify.”

Ozone — a naturally occurring molecule composed of three atoms of oxygen — has higher oxidizing potential than other reagents such as hydrogen peroxide, permanganate, chlorine dioxide, hypochlorous acid and chlorine gas. For this reason, ozone has been used for more than 100 years as a decontaminant for a variety of applications ranging from drinking water to wastewater treatment. But never before has science and technology combined in a way that so reliably and effectively delivers ozone for whole room sanitization of food and beverage production environments.

Dow’s AOS Certified technology is incorporated into an automated system that’s custom engineered to each customer’s food production areas. All systems are simple to use and feature advanced diagnostics to track and certify every treatment cycle.

AOS Certified for whole room sanitization is the latest innovation in a diverse portfolio of customer-focused sustainable technologies from Dow Microbial Control. Learn more about AOS Certified technology online at or in person at Booth #821 at the 2013 International Association for Food Protection Annual Meeting, July 28-31 in Charlotte, N.C.
