Why UV could be a better Sanitizer for Swimming Pools?
- UV-C light 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) neutralized by UV-C light are Cryptosporidium parvum and Giardia lamblia; chlorine will not affect these. UV-C is effective against all microorganisms for example also the Pseudomonas, papillomavirus and e-coli. A secondary disinfectant must be added to the water to ensure that the water actually in the swimming pool is disinfectant as well as disinfected. The most commonly used secondary disinfectants are chlorine based chemicals.
- UV-C kills destroys the chloramines (The smell of pool water changes to better. This is because of the lack of chloramines in the swimming pool). As a by-product of the disinfection process, chlorine combines with bathers’ body fluids in the pool water and form chloramines. Chloramines are unpleasant substances that cause eye, skin and nose irritation, breathing difficulties in young children, an unpleasant smell and last but not least, damage to tiles, grouts, handrails and other fittings. UV light destroys chloramines, thus reducing or even practically eliminating the undesirable side effects mentioned above of the use of chlorine based disinfectants.
- Because UV-C disinfects the water, you don’t need chlorine to disinfect the water, you only need chlorines to make it disinfectant. This makes sure you are able to decrease the amount of chlorine to a max of 80% (depending on the type of pool). Chlorine increases the PH value, Less chlorine means less increase of PH. This means you also need less PH or another acid. Less acid makes sure the bicarbonate level is longer stable and needs less corrections. When it’s a saltwater pool, less Chlorine means less salt. You also need less shock. UV-C kills the bad chloramines, this means you’ll need to do less maintenance to the swimming pool due to chloramines. This decreases the maintenance costs.
