Researching and developing water treatment products and components reveal a lot of information and observations. A recent study on the efficacy of porous PTFE tubing for the transfer of gases, such as ozone or oxygen, into water proved some very interesting theories and revealed some additional data. One test done on lake water (Water Quality Products, December 2004)1 proved very beneficial in reducing bacteria. The comparison of ozone transfer against several sizes air stones and a venturi in this test was also very interesting.
What method works best and why?
Two years of research has produced a new disinfection method for drinking water distribution system using ozone technology. This innovation is called Rapid Pipeline Disinfection and can disinfect a pipeline in about one hour as compared to traditional methods using chlorine that can take up to 24 hours or more.
Water quality leaving treatment plants of North American water utilities is exceptional and protects public health thanks to a variety of treatment tools these water treatment professionals have at their disposal.

Recent studies were conducted on porous PTFE tubing to test the efficacy of how well the tubing transfers ozone into water.

Recent research has shown that ozone treatment has many advantages over chlorine and other available anti-microbial agents. A key advantage of ozone over chlorine is that it not only kills bacteria, but it also destroys viruses and waterborne parasites.
The Desert Pain Institute of Mesa, Ariz., wanted an ecologically sound disinfection option for the therapeutic pools and spa in its new facility. Ultraviolet (UV) systems from Aquionics were paired with peroxide disinfection to provide a sanitary pool environment for the facility's aquatic rehabilitation services.

A new technology shows promise for measuring dissolved ozone and can be used in applications such as bottling plants, water stores and food and beverage plant process water treatment.

Because of the relative and perceived ease of ozone treatment, many bottlers still don't use proven ozone process controls and monitoring technology. Thus, they're yet to assure precise ozone treatment, which is necessary when certain contaminants--such as bromide, from which bromate is formed--are present in the source water. The careful use of controls can result in bottled water of a higher quality.
We will now wrap up The O-Zone Tech Workshop with an ozone quiz. This will be a good chance for you to determine if what has been given has made it into your memory banks or reference library.
