Since 15 years Technol is producing ozone reactors and filters with PVC internal lining which proves to be a good solution for ozone installations.

Ozone has been in use for over 100 years, primarily in Europe and was first put to use for water disinfection, odour control and in medical hospitals. Even though Ozone systems have been in regular use in Europe and other areas of the world since the 1950's, pools generally rely on chlorine.

Because of its strong oxidation and disinfection mechanism, ozone is very suitable for swimming pool water treatment as an alternative to chlorine based pools. Ozone is an aggressive gas and it tends to concentrate in the top part of the filters causing damages on the interior liner of the filters.

Despite the fact that some filters producers promote vinylester liner as ozone resistant, PVC liner is the only long-term solution.
