With more advanced Ozone generators and higher efficiency in dissolving Ozone into water, Ozone purification of swimming pools has become a reality. With correct desing and installation it is possible to use only Ozone purification to clean Swimming pools and Spa Baths.
The Benefits of Ozone purification in comparison with Chlorine
Ozone purification creates no harmful residues. Ozone purification is the perfect environmental solution. Only natural Oxygen is left behind. Chlorine is known to create chemical residues (Chloramine, THM material which is connected to the increased likelyhood of Asthma, respiratory damage, miscarriage and also cancer according to medical research from USA; Canada; Norway; Australia and Belgium).
Ozone purification does not increase any solids in the pool and binds organic material (oil fats, excrement ,etc), together, thus Increases the efficiency of the Filtration System so the pool will be clearer and cleaner.
Ozone purification has no smell and does not cause discoloration of bathing suits.
Ozone purification kills bacteria and germs and is effective against viruses.
Ozone purification produces no harmful residues,meaning no special cleaning is needed for the outfall waters from the Pool to sewage systems. Chlorine cleaned Pool water needs to be cleaned and treated before entering a sewage network.
Ozone causes less corrosion to the pipework. Maintenance is therefore considerably reduced.
Why is Ozone Purification not used in all Swimming Pools
It is not possible to transport Ozone gas due to short half-life time and it has to be made by Ozone generator at the place of use.
Start-up costs with Ozone purification are therefore higher than with traditional Chlorine purification systems. This start up cost pays back in savings in chemical costs and reduced maintenance costs. Alongside the sought after health benefits of a cleaner and healthier Swimming Pool.
Part of the problem in the take–up of Ozone purification is that architects and Engineers have little technical knowledge of how Ozone Technology has progressed in the last 10 years. Installations set up 10 -15 years ago suffered from technical faults that today have long been solved. Although Ozone systems have been used since 1950. Swimming pools have continued to be built with Chlorine systems on the advice of Engineers which specialized in the use of Chlorine systems. The designers need to be informed of the new technologies and how the can use Ozone to clean swimming pools.When a pool system has been designed and correctly installed any inspection will prove the economic viability of ozone as a pool purification system.
