Ozonation as a method of treating water was introduced back in the 18s. Ozone water treatment systems are common in Africa, Europe and Asia. The United States has since switched to other methods, although they still use it. It is one of the most effective and best water treatment technique that has ever been invented. This technique accounts for the safe and good taste of bottled water.
Most first water packaging businesses almost closed. This was due to partial treatment of packaged water. Current success seen in water bottling businesses it tied to ozonation. Studies have revealed that proper and procedural observation of the process delivers quality packaged water. This is however, only achievable if authorized technology and procedure is observed.
Before invention and application of this method bottlers applied other techniques that later proved to be infective and unreliable. The bottling system was in its infancy and in need of a lot of improvements. The sealing of bottled water was not done properly. Airborne organisms and air could always enter bottles during squeezing and handling. This meant that microorganisms could always grow after several days of storage. Resulting in odor, bad taste and health problems to consumers.
Ozone can be synthesized from oxygen in an electric discharge generator. The output of most electric generators has been increased from two percent weight to almost ten percent weight. The increase in is terms of feed gas stream. Ozonation takes place in a contractor where the gas is bubbled into water from a gas stream. The gas dissolves in water whereas all undissolved gas is passed to the decomposer where it is decomposed prior to release into the air.
All excess ozone undergoes decomposition to prevent air pollution. This is according to World Health Organization stipulations regulating the amount of such gases escaping into the atmosphere. As of now the allowed concentration figure is under 0.1 milligrams per liter. Ozone being both a good oxidizer and disinfectant in preferred to other products. Majority of municipal water treatment facilities use this technique.
A reactor is necessary in the process for various reasons. It allows time for the reaction to take place for the required duration. In other words it allows contact time, during which oxidation, disinfection, decomposition and other reactions take place. Disinfection is effective against all parasites, bacteria, and viruses that may be present in the water. Essentially all microorganisms are killed at this level.
Disinfection extends to all bottles including reusable ones. Oxidation which involves the addition of ozone gas is efficient against organic materials that cause odor and taste. It is equally effective against sulfide, iron, and manganese ions. Most treatment objectives can be achieved leaving no traces of chemical residual or taste when applied appropriately.
In summary, as much as the method has its bad sides the good sides outweigh them. As a result a good number of nations have approved its application by water treatment and supply plants. Some have extended the permission to treatment, processing and storage of foods. It is being suspected that cancer causing bromated ions is produced when bromide and ozone ions react.
