QuickPure™ Technical Details

If this is more than you wanted to know, don't say we didn't warn you!

QuickPure™ technology is based on ozone.

What is ozone? A form of oxygen with three atoms per molecule (O3) rather than two atoms per molecule (O2) as there is in the air we breathe. Ozone is a souped-up form of oxygen (they also call this activated oxygen) that attacks impurities and kills germs by oxidation.

How's it made? QuickPure™ devices make ozone by treating oxygen in the air with an electrical corona. The corona breaks some of the oxygen molecules apart into oxygen atoms, which then combine with an oxygen molecule to form triatomic oxygen, which is ozone. (Other methods of producing ozone for this application are impractical. For example, the electrochemical method is very expensive and possibly hazardous, and the UV method does not produce a sufficient concentration of ozone.)

Then what happens? The ozone molecule is unstable, and, depending on conditions such as temperature, it soon (usually after less than an hour) reverts to ordinary diatomic oxygen. So, ozone must be used as it is made. The higher the concentration of the ozone gas produced, the higher the concentration of the ozone that can be dissolved in water. And, the higher the dissolved ozone concentration, the better it works. The patented QuickPure™ ozone generator produces the needed high ozone concentration at a much lower voltage than conventional ozone generators which means that the appliance is much smaller, lighter and lower in cost.

How does the ozone made from air get into the water? To purify water and surfaces contacted by the water, it is necessary to dissolve ozone in the water. Although ozone is much more soluble in water than oxygen, it is still difficult on a small scale to achieve a sufficient dissolved ozone concentration to be effective. However, Alab has invented new methods of doing this...allowing customization for different product designs.

Tiny Bubbles: For example, one patented method is the result of basic research on the factors that control bubble size. By reducing the size of the ozone-containing bubbles by 80%, ozone can be dissolved about 5 times faster. (For more on bubbles, see the Alab Diffuser page.

Once sufficient ozone is dissolved, it is necessary to hold the water with the dissolved ozone for a sufficient time that the ozone can destroy all the germs. The higher the ozone concentration, the shorter the necessary holding time, and the smaller and less expensive the holding system.

One of the great advantages of ozone is that the amount of ozone that will dissolve is self-regulating. The excess ozone is changed back to ordinary oxygen by passage through a catalyst before it is released to the atmosphere. Thus, QuickPure™ technology eliminates problems that could cause variations in purification.

The U.S. Environmental Protection Agency has established values for what is called the CT Factor, which research and experience have shown to kill the most resistant germs. C stands for the concentration of ozone in parts per million and T is the time of contact in minutes. QuickPure™ technology can substantially exceed the EPA CT Factors.

Anything Else? Ozone removes some impurities such as iron and sulfur by precipitation after oxidation, and it causes particles that produce cloudiness to stick together so they can be filtered out. Alab recommends that activated carbon be included in the filter so that any residual ozone in the water is removed, and to increase removal of chemical contaminants. As the water is filtered under pressure, additional elements can be added to the filter as desired for special treatment of the water. Pre-filtration designs are available for turbid water. Water is not heated by ozonation, so cold water stays cold.

Competition? What about the other guys who claim to offer similar small dissolved ozone systems? The short answer is that our patented technology really works, and we have not seen any competitive technology that does. The most common competitive failures are; they do not make enough ozone, they make too low a concentration of ozone to be effective, very little of the ozone that is made is dissolved in water or there is insufficient contact time between the dissolved ozone and water. Typically, competitive small ozone generators produce ozone at less than 100 PPM concentration compared to more than 15,000 PPM for a QuickPure™ ozone generator. The Henry's Law constant for ozone means that 100 PPM ozone gas concentration cannot achieve a significant dissolved ozone concentration. If a device claimed to be competitive lacks a means for destroying excess ozone such as used in all QuickPure™ products, then it is either illegally venting more than 0.1 PPM, or is ineffective.
