Swimming pool disinfection

Swimming pool disinfection is essential to keep the water we swim in free from bacteria and germs.


Disinfection also plays a part in controlling the organic debris from products used on the body, such as deodorant, creams and oils.

Traditional disinfection is done using chlorine but this comes with several drawbacks:

  • Red eyes
  • Irritated skin
  • Strong, unpleasant smell
  • Allergic reactions
  • Very dry hair

At higher levels of exposure (frequent swimming) chlorine has been reported to cause symptoms associated with asthma, such as wheezing, coughing and tightness in the chest.

How do I protect myself from chlorine in swimming pools

Indoor pools pose more of a danger compared to outdoor pools and spas.  This is due to toxic gases such as nitrogen trichloride being released.  Nitrogen trichloride is a by-product from the chemical reaction between chlorine and ammonia which is prevalent in swimming pools. When this gas is inhaled, it can cause severe damage to the lining of the lungs. It is harmful for a person of any age however, young children and the elderly are most at risk.

Alternatives to chlorine

Whist chlorine is used in outdoor pools, the toxic gases dissipate into the air so do not pose as big a threat to the swimmers. Unfortunately, not everyone has the luxury of an outdoor pool (certainly not here is Scotland!)

These all come with pro's and con's which play a part in the decision making when looking for a chlorine alternative.
