Question

Ozone is passed through the swimming pool because it
a. Absorbs UV radiations
b. Acts as disinfectant
c. Easily available from Oxygen
d. All of the above

Answer 1

Hint: In some countries, sodium hypochlorite is used as a disinfectant and also as an oxidizer, where this sodium hypochlorite increase the Ph value of the water, and if the water has a Ph value of 6, 5 like that it is good to use chlorine as an oxidizer and disinfectant.

Complete answer:
- Ozone is used in the swimming pools as a disinfectant because it has many advantages compared to conventional disinfectants like chlorine.
- Chlorine is a man made chemical that is used in a wide range and at the same time it is also a disinfectant in the swimming pools.
- Exposure to chlorine water has some risks like getting allergies and asthma and it may cause some long term effects.

But, ozone has many advantages which include,
- The first thing is no chlorine smell, and it oxidizes with both organic and inorganic molecules and it won’t produce any byproducts like chlorine.
- The quality of water is healthier and safer for the active swimming pool users.
- It reduces the cost of buying chemical products for the long term.
- Ozone has no toxic residues compared to that of chlorine water.
- It prevents eye irritation.
- It prevents the staining of the bathing suits.
- It prevents clogging and it increases the filter capacity.
- Ozone has a wide range of use in water filtration, odor control, and medical fields.

Hence, The correct answer is option (B).

Note: Ozone has more filtration ability as it is capable of bio-degrading the organic molecules and large molecules are broken down into the smaller ones, so they can be filtered easily and disinfecting the swimming pool with ozone gives the freshwater look.
