OZONE DRINKING WATER TREATMENT
Ozone is an excellent disinfectant with the superior ability to kill viruses and biological contaminants found in water. It is also a very powerful oxidant that can oxidize metals in water such as manganese, iron and sulfur into insoluble particles, aiding in their filtration and removal from water. Oxidization by ozone in water purification also aids in removing taste and odor problems from water much more efficiently than chlorine, and ozone itself doesn’t produce any odor or taste. Due to the fact that ozone consists of oxygen, it reverts back to pure oxygen and disappears without a trace after it’s been used. Not only does ozone remove microorganisms from water, it also halts the accumulation of deposits in your pipes and water system which greatly improves the quality of your water. Another very important benefit of water purification using ozone is that no chemicals are added to the water. Ozone is a naturally occurring substance and when utilized for water purification purposes it immediately degrades back to oxygen leaving no trace.
Ozone is composed of three Oxygen atoms. One of the atoms is connected to the others weakly and will transfer itself to other substances such as viruses and bacteria, causing them to oxidize by binding itself onto them.
Water purified by ozone is now free of protozoa, fungi, germs and bacteria and is safe for human consumption. Ozone water purification accounts for more than ninety percent of the world’s purified water and most bottled waters are treated by ozone. There is a new trend in which some pool companies have begun to use ozone water purification instead of traditionally used chlorine due to the fact that it has less undesirable side effects.
