Geschiedenis

UV-C light at a particular wavelength (253,7nm) is a very powerful germicide. It deactivates and renders harmless waterborne pathogens that are completely unaffected by chlorine based disinfectants. Examples of dangerous pathogens (viruses and cysts) neutralised by UV-C light are Cryptosporidium parvum and Giardia lamblia; chlorine will not affect these.

UV-C cannot, however, be used on its own. This is because after the pool water has been subjected to treatment with UV-C, it is disinfected but not disinfectant. A secondary disinfectant must be added to the water to ensure that the water actually in the pool is disinfectant as well as disinfected. The most commonly used secondary disinfectants are chlorine based chemicals.

Although chlorine is a good disinfectant (although not as powerful as UV-C), it has one major drawback. As a by-product of the disinfection process, chlorine combines with bathers’ body fluids in the pool water to form chloramines. Chloramines are unpleasant substances that cause eye, skin and nose irritation, breathing difficulties in young children, an unpleasant swimming pool “chlorine” smell and last but not least, damage to the fabric of the pool such as tiles, grouts, handrails and other fittings.

A second advantage of the treatment of pool water with UV light is that it destroys chloramines, thus reducing or even practically eliminating the undesirable side effects mentioned above of the use of chlorine based disinfectants.

VGE’s “Blue Lagoon” range offers the solutions mentioned above. The economical comparison of the various solutions depends very much on pool size, design and usage. The capital and running costs and capital costs of disinfection systems should be considered for every pool on a case by case basis.
