Public pools:

The UVOX Redox® Process guarantees safe disinfection, the removal of Combined Chlorine and leads to cost savings.


  • Absolutely safe and efficient disinfection of all microorganisms (up to 96 %)
  • Legionella protection, as the activated carbon layer will be taken out off the filter
  • Reduction of the free Chlorine level to the minimum (only for depot disinfection purpose in the basin)
  • Reduction of unwanted DBP’s (Chloramine, THM etc.)
  • Reduction of hazardous micro pollutants
  • No unpleasant smell or taste
  • Not aggressive to eyes, skin, hair and throat
  • Savings on water, energy and chemicals
  • Reuse of water
  • Sustainable and economical way of water purification

Swimming is a popular recreational activity, also recommended for its health benefits.

However, besides the health benefits derived from swimming and recreational water activities, the swimming pool environment exposes to people (infants) different health risks.

These health risks are associated with exposure to microbial and chemical contaminants.

Chlorine is used for the purpose of disinfection in many public pools and hot tubes. However, some pathogens have proven to be resistant to chlorine (e.g. Cryptosporidium oocysts and Giardia cysts) and therefore these can still pose a threat to the health of bathers. Chlorine based disinfectants have been found responsible for disinfection by-products (DBP’s) formation, due to the reaction with organic and inorganic constituents in the water.

Free Chlorine reacts with the so-called micro pollutants immediately to DBP’s such as combined Chlorine (mono-, di- and tri-chloramines) and strongly irritate eyes, hair, shin, nose and throat. A THM is even carcinogenic already at low concentrations (0.02 mg per Liter).

According to the WHO guidelines the levels of free chlorine, which are currently considered to be acceptable in order to achieve adequate disinfection, while minimizing the users discomfort.

In public pools the minimum dosage varies to a large extend (0.3 to 5.0 mg per Liter). Legally combined chlorine (Chloramine) must not exceed 1 mg per Liter in any public swimming pool and spa pool. Pool operators should ensure as best practice, that combined chlorine never exceed half of the concentration of free Chlorine. In Europe the regulations are much stricter.

The triple UVOX Redox® process combines the oxidizing effect of ozone with the disinfecting effect of ultraviolet light and initiates meanwhile a highly effective advanced oxidation process (AOP) in one single system with one single lamp.

After some successful long term pilot projects in heavily frequented school, hospital pools, the company Wapure International GmbH developed and patented the UVOX Redox® mainstream process.

UVOX Redox® participated in EU project “demEAUmed”

Demonstrating integrated innovative technologies for an optimal and safe closed water cycle in Mediterranean tourist facilities (DemEAUmed)

We are proud that Wapure International GmbH has been elected as partner for UV-Disinfection, Ozonation and Advanced Oxidation Process (A.O.P.) to participate in the EU research project demEAUmed.

Demonstration of innovative water treatment solutions

The DemEAUmed project is an European project co-funded by the European Union under the 7th Framework Program. The aim of the project is to demonstrate integrated innovative technologies for an optimal and safe closed water cycle in Mediterranean tourist facilities.

At the demonstration site Hotel Samba in Lloret de Mar, Spain  innovative water treatment technologies will be properly combined and tested. Please find more information on the project website:

Here you can download the extensive test results of the demEAUmed project.

Using these test results, the UVOX Redox® process has been patented for many applications.We are happy to inform you in detail about the UVOX process and its use in the different areas of water treatment.

We are happy to inform you over the triple UVOX Redox® process as a sustainable and state-of-the-art method of water purification for public pools, sauna´s and hotels.
