Instructions for safely and effectively treating swimming pool water with Chlorine

If we treat water with chlorine for swimming pools properly and in the right dosage, it will ensure effectiveness and maintain clean and safe water for everyone. To know more details about how to use chlorine chemicals in swimming pool water treatment, let's take some time to read the following article by Dong A.

1. Advantages of utilizing chlorine for water treatment

Chlorine is another name for Calcium Hypochlorite (OCl) 2 , known for its white powder and characteristic odor. It is an inorganic mixture of lime and calcium chloride containing high concentrations of chlorine, easily soluble in water, capable of releasing chlorine gas when dissolved, giving the water a pungent odor.

After dissolving chlorine solution in water, this chemical will decompose into HOCl (hypochlorous acid) and OCl- (hypochlorite ion). These substances have the effect of killing bacteria, and microorganisms and adjusting the pH level in pool water. In addition, this substance also helps eliminate unpleasant odors in the pool water as well as ensure safety for people when swimming. That is also the main use and benefit of chlorine solution when used in swimming pool water treatment.

2. Standard dosage of chlorine for swimming pool water treatment

At present, Chlorine is still used as an effective water treatment chemical, widely used in swimming pools, domestic water treatment, production or industrial wastewater. Specifically:

In case the swimming pool is operating normally, to treat water with Chlorine, you need to use a daily dose of 500 - 700g/ 100m3 under normal conditions.
In case guests use a crowded swimming pool, the pool water must be vigorously aerated and the weather turns hot and windy, the dose of required Chlorine will be higher, about 1000g/100m 3 .
For swimming pools with moss and algae, you need to use about 3.5 - 4 kg/100m 3 to completely destroy and clean the water.

3. Instructions for using Chlorine chemicals in swimming pool water treatment

Actually, the way to use chlorine chemicals in the swimming pool water treatment does not have too many complicated details. You just need to check the water concentration in the lake, if the chlorine index is lower than the allowed level, just proceed with treatment. Specifically:

Instructions for use of Chlorine pellets

Customers can consider using fast disinfection pellets or slow disinfection pellets depending on their needs. For quick disinfection chlorine pellets, the standard dosage is 10 pellets of 2 - 2.5 grams or 1 pellet of 20 grams per 1m 3 of water.

If the swimming pool has a volume of about 50 - 100m 3 , each time you need to use up to 100 pellets of 2 - 2.5gr or 10 pellets of 20gr to maintain the cleanliness of the water for about 2 - 3 days. However, in case you want to increase water cleanliness for 7 - 9 days, you need to use up to 200 grams of chlorine for a 50m 3 pool.

Instructions for use of chlorine powder

Customers who use chlorine to clean pool water in powder form need to dissolve it in a bucket/basin first before pouring it into the pool. Note that, during the process, you need to use a bucket/basin that is resistant to corrosion to dissolve Chlorine and after dissolving, you must let the solution settle before pouring it into the pool.

4. Pros and cons of employing Chlorine for water treatment

Although using chlorine to disinfect and treat water in swimming pools brings many outstanding advantages, there are also some limitations as follows:

Advantages

Chlorine has the ability to disinfect and kill bacteria extremely well, so it effectively helps eliminate all pathogens harmful to humans in water.
Compared to many chemicals used to treat swimming pool water today, chlorine is rated higher as it provides good results at low concentrations.
The time required to treat swimming pool water with Chlorine is extremely fast with a wide operating pH range, from low to neutral, but in general the most optimal level is about 7.2 - 7.6.
Using chlorine to treat water brings long-term effects, it can keep the water of the swimming pool clean and safe for 7-9 days.
When customers use the correct dosage recommended by the manufacturer, it will help chlorine develop strong oxidizing properties but will not cause corrosion.
The price of chlorine chemical products is not too high but still provides fast, long-lasting results with low concentrations, good cost savings.

Disadvantages

Although it possesses many advantages, chlorine causes a strong, unpleasant odor, especially when used with high concentration. In addition, it also has the ability of causing irritation in humans with main symptoms such as pain, burning, and itching. Clothes or swimsuits after swimming, if not washed, can easily fade, discoloured, and tear more easily than before.

Besides, some cases of chlorine leaking or overdosing are more difficult to fix and treat. In particular, chlorine chemicals also pose a high risk of causing fire and explosion when used and stored improperly.

5. Noted things upon water treatment with Chlorine

Chlorine in general or chlorine gas in particular are extremely toxic, so during its use, you need to pay attention to the following issues:

Must be fully equipped with protective equipment such as glasses, masks, shoes, and gloves when having direct contact with chlorine chemicals.
Because chlorine can dissolve, it should be used in a well-ventilated and airtight place to limit the risk of chemicals sticking to the body or causing stuffiness and difficulty breathing.
In case you feel uncomfortable and suspect chlorine poisoning, customers must quickly go to medical facilities to get tested as quickly as possible.
Always carefully calculate the content and concentration of chlorine to use to limit under- or over-dosage, affecting use and effectiveness.
