Ozone disinfection enabled the water bottler to produce high-quality, storage-stable bottled water free of byproducts and the taste and odor associated with the use of chlorine for disinfection and oxidation. These characteristics and the claims of good-tasting, odor-free, pollution-free, healthy water led to the rapid growth of the bottled water industry through the '80s and '90s with overall public consumption growth consistently approaching or exceeding double-digit rates.
Ozone (O3) is a gaseous material made from oxygen in an electric discharge field (corona discharge) type ozone generator. Early ozone generators operated at 1 to 2 percent weight (% wt.) ozone. Today, the output of the ozone generator typically contains 3 to 10% wt. of ozone in the unreacted oxygen feed gas stream. This ozone gas stream is brought into contact with the water to be treated in a device called an ozone contactor. In the ozone contactor, the ozone is dissolved in the water and the undissolved ozone in the off-gas is discharged through an ozone decomposer and released at rooftop levels.
Ozone is a powerful oxidant and an exceptional chemical disinfectant. The ozone treatment process is an integral part of the drinking water treatment plant operation in more than 3,000 municipal water installations worldwide. These plants supply water to the residents of many major international cities such as London, Paris, Budapest, Kiev, Moscow and Singapore. In the United States alone there are nearly 400 ozone drinking water installations including those in Los Angeles, Dallas, Milwaukee, Orlando and Atlanta, and more are coming to Boston and New York City.
The ozone/water contacting system serves two primary functions. First, it is used for the dissolution or mass transfer of the ozone gas from the output gas stream mixture of the ozone generator into the water to be treated. The balance of the ozone remaining in the off-gas is destroyed by an ozone decomposer unit so that any off-gas discharged into the atmosphere contains an ozone concentration less than 0.1 parts per million (ppm)--or milligrams per liter (mg/L)--of ozone.
Second, the ozone contactor is a reactor. It provides the reaction time--detention or contact time--to allow the desired disinfection and/or oxidation processes to occur in the water. Once the ozone is dissolved in the water it undergoes three simultaneous reactions.
The objectives of ozone treatment in water bottling include the following.
Ozone treatment is a unique and valuable process. It can accomplish all the aforementioned treatment objectives without leaving a taste or chemical residual behind when accurately applied and controlled. Ozone is an exceptionally powerful disinfectant and oxidant. It does its job and disappears. With appropriate pretreatment and careful monitoring and controls, it can leave water relatively free of disinfection byproducts as well.
