Basics Of Ozone Water Treatment Systems

By Anna Thompson


Introduction of ozonation dates back in the 18s. Ozone water treatment systems are commonly applied in Asia, Africa, and Europe. The US has since shifted to other techniques, though they still apply it. Ozonation is efficient and is regarded as one of the best technique ever. This technique is behind all the good taste and safety of bottled water. Water supplied by some municipals is also safe for consumption thanks to this technique.

Most businesses venturing in water packaging as the beginning were almost forced out business. The main cause was improper treatment of water. Invention of ozonation rescued most of them and saw them succeed. High quality water is produced when the disinfection process in followed accordingly.

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.

Artificial manufacture of ozone is possible in an electric discharge generator with oxygen as the main material. The efficiency of most generators has been improved from the 2 percent weight to about 10 percent weight that is in the feed gas stream. The process is such that at the ozone contractor the water is brought into contact with ozone gas stream. In the contractor the gas dissolves in the water while undissolved gas is decomposed in a decomposer before being released 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.

Reactors are needed in ozonation for several reasons. They allow time for reaction to occur for specified period. Basically it allows contact time for decomposition, oxidation, disinfection, and other reactions to occur. Viruses, bacteria, and parasites present in water are killed during disinfection. Almost every microscopic organism is killed at level.

When disinfecting all areas including bottles are treated. Oxidation usually entail adding ozone gas to water is effective against most odor and taste causing substances. Oxidation also takes care of ions such as manganese, sulfide, and iron. Ozonation is efficient such that when properly applied it does not leave traces of taste or chemicals.

To conclude, the advantages of using this technique in treating water surpass the disadvantages. This has seen most countries approve the use of the method by water supply and treating facilities. Some countries have gone ahead to allow its use in processing, storage, and treatment of foods. It is suspected that the reaction between ozone and bromide ions produce bromated ions which are carcinogenic.
