Chlorine importance in Swimming pool water

 Chlorine is added to swimming pools for several reasons. First and foremost, it helps to kill and control the growth of harmful bacteria and other microorganisms that can thrive in warm, moist environments like swimming pools. This is important for ensuring that the water in the pool is safe and healthy for people to swim in.

In addition to disinfection, chlorine can also help to oxidize or break down organic matter in the pool water. This includes sweat, urine, and other bodily fluids that can contaminate the water and contribute to the growth of harmful bacteria. By breaking down this organic matter, chlorine helps to keep the water clean and clear.

Finally, chlorine is added to swimming pools to help balance the pH of the water. The pH is a measure of how acidic or basic the water is, and it can affect the effectiveness of chlorine as a disinfectant. By keeping the pH in the appropriate range, chlorine can work more effectively to keep the pool water clean and safe.

Overall, adding chlorine to swimming pools is an important part of pool maintenance and helps to ensure that the water remains safe and healthy for swimmers.

Quality Tolerance as per IS 3328 (1993), it is a standard set by the Indian Standards Institution for the quality of water in swimming pools. According to this standard, the acceptable limits for various chemical parameters in swimming pool water are as follows:

pH: 7.0 to 7.8

Free Chlorine: 0.5 to 2.0 mg/L

Total Alkalinity: 80 to 120 mg/L as CaCO3

Calcium Hardness: 200 to 400 mg/L as CaCO3

Total Dissolved Solids (TDS): Up to 1000 mg/L

These limits ensure that the swimming pool water is safe for use and does not cause any harm to the swimmers. It is important to maintain these limits regularly by testing the water and adjusting the chemical levels as needed to ensure the water quality remains within acceptable limits.
