The Sun as a role model

The sun radiates light in different wavelengths (nanometer nm) to the earth. Some of this is visible light (colour spectrum) and some is not visible to the human eye. For the preparation of water, however, only ultraviolet light with a wavelength of 185 to 315 nm is of importance.

The ultraviolet rays of the sun kill off morbiferous microorganisms within seconds, thus preventing further spreading. The primary damage to the microorganisms during ultraviolet irradiation is based on a photosensitive alteration of the nucleic acids that prevents cell division. A very effective disinfection is achieved through this.

The most efficient disinfection is achieved by ultraviolet rays with a wavelength of 254 nm.

Ozone (O3) is formed due to ultraviolet irradiation at 185 nm. It breaks down easily upon formation of oxygen and is thus deemed to be a good disinfectant and oxidant of many water-soluble, (partly persistent) substances.

The UVOX process

The trendsetting UVOX Redox® process combines the disinfecting effect of ultraviolet light with the oxidizing effect of Ozone and Hydroxil Radicals in one single system with one or more special UVOX Redox® lamp(s).

The UVOX Redox® triple purification process guarties guarantees a 99,99 % killing rate of all bacteria, viruses and algae and other hazardous pathogens.

Furthermore it removes efficiently micropollutants, such as hormones, pesticides, biocides, disinfection by-products (DBP`s), body fluids, odor, and rest of pharmaceutical products and medicine.

Description of the UVOX Redox® triple purification process:

By means of the special UVOX Redox® UV-lamp, air is irradiated with ultraviolet light with a wavelength of 185 nm. The oxygen content in the air is converted into ozone as result of this ultraviolet irradiation. Ozone already leads to the oxidation of pathogenic germs (bacteria, viruses and algae) and  micropollutants. This air mixture then is injected into the water by mean of a special Ozone injection device.

In the UVOX reaction chamber, Water and the Ozone / air mixture are then (again) irradiated with ultraviolet light (254 nm).

Es result of this, two processes are taking place:

The UV- dissinfection as result of the irradiation with UV (254 nm) is initiated.

The diluted ozone content is converted into hydroxil radicals, whereby the relative oxidation potential is increased from 1.52 (value Ozone) to 2.05 (value hydroxil radicals).

This process of advanced oxidation (A.O.P) is the most effective form of oxidation and is unique to the UVOX Redox®. As result of the advanced oxidation process, many resistant microorganisms, such as Legionella, Cryptosporidium, Giardia and Sars-CoV-2 are desroyed very effectively. Furthermore, the advanced oxidation process breaks-down many noxious, and highly persistent micropollutants.

The remaining ozone content is destroyed.

The UVOX Redox® triple purification process will lead to:

Up to 99,999% deactivation of all microorganisms, such as bacteria, viruses, fungi, algae, protozoa, and molds. Even hazardous species, like Legionella, Cryptosporidium, Giardia and Sars-CCoV-2 will be deactivated.

A very effective reduction of many very persistent micropollutans as result of the advanced oxidation process (A.O.P.).

  • The UV- Disinfection guarantees a 99,9 % Killing Rate of all Bacteria, Viruses and Algae and other harzardous Pathogens.

  • An additional Ozone Oxidation (Ozonation).
  • An `Advanced Oxidation Process` (AOP) in order to reduce serveral persistent water solved compounds:

    • Dechloramination
    • Reduction of micro pollutants
    • Reduction of Pesticides and Biocides
    • Reduction of Medicine, Hormones and Anti Biotica.
    • Break down of Amoniac, Amonium and Nitrite (Aerobe Waterpurification)
    • Reduction of unpleasant Odor, Smell and Taste.
    • TOC Reduction
