CASE STUDY: Medical Center Releases Findings on Aqueous Ozone Cleaning System
Contributed by CleanCore
Whenever a totally new technology is introduced into the professional cleaning industry, the first thing facility cleaning executives want to know is whether the technology works. If they find it does work, then they want to know how it will help them do their most important job, which is keeping building occupants healthy.
This process is happening now with what is called “engineered water” cleaning systems. These systems do not use traditional cleaning solutions in order to clean surfaces and fixtures. There are different types of equipment that come under the umbrella of engineered water, but the one that seems to be garnering the most attention is called aqueous ozone.
When used for cleaning, aqueous ozone is often referred to as “greener than green cleaning.” Aqueous ozone systems create ozone — which is naturally found in the atmosphere — mechanically and then infuse it into water. The end result can then be poured into a sprayer, just like any cleaning solution, or released through the unit itself for cleaning floors or carpets, for instance.
But, does it work?
That was recently answered by two studies conducted by the University of Nebraska Medical Center (UNMC) after using aqueous ozone generated by CleanCore Technologies Ozone Systems. Entitled Qualification of Surface Disinfection, the studies found that aqueous ozone cleaning systems can prove very effective at eliminating what are called colony-forming units (CFUs) of both Escherichia coli (E. coli) and Listeriosis (Listeria) from hard surfaces. If ingested, these bacteria can produce food poisoning-type symptoms that can be very harmful, even resulting in death.
The UNMC report concluded, “there was a statistically significant decrease in E. coli and Listeria CFUs found on the [treated areas].” The cleaning power of the CleanCore systems were also compared to the main bacteria-killing ingredient found in many hospital-grade disinfectants, Peracetic Acid (PAA). The report concluded, “in several instances, there was no significant difference in reduction of E. coli and Listeria between the aqueous ozone solution and the positive control PAA.”
So it’s clear, the CleanCore Aqueous Ozone system does work. Now, about our other question: How will it help cleaning workers do their main job, which is to keep people healthy? It appears the UNMC answered this question, as well.
