The Science

Engineered water technologies are proven to produce safe and effective alternatives to chemical cleaners, deodorizers, sanitizers & disinfectants. Better for people & the planet.


Requires only air, water and electricity to produce a highly effective cleaner-deodorizer-sanitizer in a single product.


Requires salt, water and electricity to produce two products – an excellent degreasing cleaner and a chlorine-based sanitizer.



aqueous ozone

o3Aqueous ozone is the name given to water that has been infused with ozone gas.  Unlike the health risks of gaseous ozone, aqueous ozone is a safe and effective cleaner, deodorizer and sanitizer.

The production of ozone in nature involves a power source – either sunlight or electricity – which acts to break apart oxygen atoms and cause a third oxygen atom to form. Once that happens O2 becomes O3.  As the O3 gas is infused into water it becomes known as aqueous (water) ozone – which we prefer to call “ozone ewater”.

Ozone in water has been used for more than one hundred years to disinfect drinking water, and is used by municipalities across the country for water purification today. In recent decades it has become an important, chlorine-free way to keep pool water sanitary. Since 2001, the USDA and FDA have approved aqueous ozone for washing food that will be eaten raw – fruits, vegetables – as well as raw meats – pork, poultry, beef, fish  – to ensure safety, as well as for the sanitizing of food processing work surfaces.

An improvement to aqueous ozone is stabilized aqueous ozone, which dramatically extends the value of the product. See the next section.

The importance of stabilizing aqueous ozone for effective use in a busy workplace.

While the value of “aqueous ozone” is clear, one weakness that needs to be addressed is that it remains effective for only a short period of time. This is why it is used predominatly in applications where water is flowing – such as from a faucet to wash produce. Stablized aqueous ozone is produced by first treating the water, much like a softener does, to make it more receptive to the ozone and keep it in useful form longer. The special stabilized form of aqueous ozone can last for a day as a sanitizer and upward of a week as a cleaner.

The reason ozone in water is effective is due to its high oxidizing potential, which is more powerful that hydrogen peroxide, and far more powerful than compounds like chlorites, hypochlorites or iodine. It is an effective and relied upon sanitizer and deodorizer because it “oxidizes” bacteria, germs, etc., including odors cause by bacteria and other organics. Extending the useful life of the product in spray bottles, mop buckets and powered equipment is a huge advantage.

A highly effective cleaning-deodorizing-sanitizing product, stabilized aqueous ozone is ideally suited to broad custodial applications. Learn more about The eWater System featuring stabilized aqueous ozone.

The Sanitizer.

The first product from an electrolyzed water generator is a sanitizer with a pH of anywhere from 7.5 to below 5. Known as HYPOCHLOROUS ACID it is the acidic counter-part to Sodium Hypochlorite (bleach). The solution has powerful germ-killing properties and has been proven in multiple studies and practical applications to reduce pathogens.  Though tough on microorganisms it is produced at a level that keeps it safe for users as it is non-irritating to skin and emits no harmful VOCs.

Due to the presence of sodium chloride (from the added salt)  in the water after the electrolytic process a slight film can appear on certain surfaces, making this product best suited to more industrial applications. The product should also be wiped from metal finishes to avoid any potential for corrosion.

The Cleaner.

The second product, known as SODIUM HYDROXIDE, is an excellent degreaser-detergent. With a pH of about 11.3, this alkaline product is a natural, safe cleaning agent that quickly breaks down stubborn oils, proteins and harmful biofilms. Fantastic as a grease-cutter and as a replacement for dishwashing detergents, it is a very good product for large kitchen settings.

Like the sanitizer, the product may leave a light film noticeable on mirrors or windows,  making it less suitable for customer-facing applications.

Here’s a video of the product in action:

Role: Change Management

The value Dr. Steff brings to eWater Advantage is dealing with the behavioral issues of learning to accept and embrace new ways of doing familiar tasks. As there is an element of uncertainty when first learning of electrolyzed water – How can “water” kill germs? – it is important we understand the psychology of gaining user acceptance. Once an employee understands the urgency of why the switch to ewater matters, they will be more eager to prove to themselves that the products work, which will create enthusiastic adoption. Dr. Steff has earned a doctorate in Workplace Leadership and Ethics as well as a Masters in Counseling.
