Swimming Pool Chemicals

Clubs, hotels, fitness centers have swimming pools in their establishments for exercise, leisure, learning, recreation and hydrotherapy. Even educational institutions like schools, colleges, universities keep water pools for physical training and competitive meets. Some pools are also dedicated for special purposes like diving, water sports and training of lifeguards and astronauts.

However, swimming pool makes the easiest medium for infectious disease transfer.

Sources of Microbial Contamination

Infected bathers can directly contaminate water and its surroundings with germs mainly sourced through unintentional let out of urine, saliva and mucus, leading to various skin infections in other bathers coming in direct contact. These infectious agents may sometimes become fatal and life threatening too.

According to a CDC weekly report, out of the 444 water borne disease outbreaks reported between 2009 – 2017, 35% were due to swimming pool water, with 13% average annual increase in outbreaks of Cryptosporidium, a leading cause of pool based water-related disease outbreaks.

Predominantly sodium or calcium hypochlorite and/ or chlorine tablets/granules are used to treat swimming pool water. They are directly fed into the water after the process of filtration. The primary reason being that chlorine acts as an oxidizing disinfectant, which effectively removes every possible traces of bacteria, virus, algae from the pool and is cost effective and readily available.

But the problem lies with stability as is it is not that particularly stable, and degrades when exposed to UV rays, readily amalgamating with other chemicals to form new products. Hence we often see the use of a stabilizing agent which reacts with chlorine to see through the UV degradation.

Why Chlorine is not safe to use?

Chlorine when reacts with water, gives hypochlorous acid which actually works as a pool disinfectant. But even with the use of stabilizer, hypochlorous acid combines with other chemicals like ammonia to form various compounds like chloramines.

These compounds do not classify as disinfectants and are also the reason behind the allergic reactions that takes place on human skin contact. Besides, chlorine is toxic and corrosive in nature and have to be carefully handled and stored.

Now you know the reason behind the distinctive irritating smell that you get in swimming pools, unpleasant odor, the itchiness in your eyes and rashes on your skin and a big board saying “Chlorine in pool” which prohibits you to dive inside.

If the water hardness is exceedingly high, the high pH hypochlorite precipitates the calcium and magnesium, which leads to formation of scales inside the pool. Hence it limits the use of free chlorine and makes it generally pool dependent.
