The use of ozone in swimming pools

Ozone (O3) is a very effective disinfection agent and can be used in swimming pools to replace chlorine and bromine containing disinfection chemicals. The advantage of the use of ozone compared to the other swimming pool treatment agents is the fact that the swimming environment will increase dramatically.

The use of ozone prevents the formation of chlorine or bromine containing byproducts, like chloramines and trihalomethanes. Ozone will even breakdown already formed unwanted chlorinated byproducts. This will reduce problems with red eyes and respiration problems. Ozone will give a sparklier and clearer bathing water.

The use of ozone has also the advantage for the swimming pool operator that less fresh water replacement is necessary, which has a big effect on the heating cost.

Some technical details:

Ozone is besides an effective disinfection agent also a coaggulation agent, which will increase the performance of the sand- and active carbon filter.

Lenntech sizes swimming pools according to the German DIN 19643 norms. In these norms amongst others a temperature dependent ozone dose is used. For swimming pools with a water temperature of 28°C or 33 - 35°C an ozone dosage of respectively 0.8 and 1.2 gram per m3 is used.

In most cases ozone systems can be retrofitted in existing systems.
