Aqueous ozone as cleaning agent
What are thoughts on using aqueous ozone (H3O) as cleaning/sanitizing agent for hospitals/clinics in general.
We have used it on our campus and it has been very positive. We currently do not use it for discharges but on projects and public bathrooms the results have been outstanding.
Jeanne, Engineered Water: Originally, there was what was called activated water, which referred to “nonaugmented tap water—in which no salt or other minerals were added—that was altered by passing an electrical current through tap water,” says Allen Rathey, president of Healthy House Institute. “The main problem was consistency-of-solution created by the inability to control tap water, which varies in its mineral content. Tap water with adequate mineral content can be properly electrolyzed, but tap water without sufficient dissolved minerals cannot.”
Today’s more recent technologies employ what has been termed “engineered water,” based on either activated ozone-infused or electrolyzed water systems.
Perhaps over-simplified, but ewateradvantage.com defines the two as “Aqueous ozone is the name given to water that has been infused with ozone gas and requires only air, water, and electricity to produce a highly effective cleaner-deodorizer-sanitizer in a single product; electrolyzed water uses salt, water and electricity to produce two products, one an alkaline cleaner excellent for degreasing and the second an acidic chlorine-based sanitizer.”
While these two types of engineered water rely on different technologies, they are similar enough that for our purposes we can discuss them together.
The first benefit of the use of these water technologies is that they release little to no chemicals or gases into the atmosphere other than those produced on site by the addition of salt or ozone. This means no fumes, no mixing of more toxic chemicals, and little if any negative impact on indoor air quality, all of which make it probably the most effective green cleaning strategy known to date.
These environmental and health benefits are not the only advantage to water-based systems, however. Among other benefits worth noting are: • Labor savings. Chemical residue left on a surface can attract soil to the surface, increasing the cleaning needs of the facility. • Increased safety. A large percentage of the injuries that happen when cleaning are due to accidents and exposure to chemicals. • Product cost savings. There are no cleaning chemicals to buy. • Enhanced sustainability. Chemicals must be packaged and delivered. When no chemicals are used, there is nothing to package or anything to deliver.
