Shock chlorination is a water treatment process which involves adding significantly more chlorine to water than is typically used for regular disinfection. As you know, the chlorine It is a disinfectant commonly used in swimming pools to eliminate pathogenic microorganisms, such as bacteria, viruses and other organic contaminants.
With this in mind, shock chlorination is carried out for several reasons and with specific objectives:
- Delete or inactivate quickly pathogenic microorganisms that may be present in the water, such as bacteria coliforms, E. coli and other infectious agents.
- Chlorine in the form of sodium or calcium hypochlorite is an effective oxidizing agent that can decompose and eliminate organic matter present in water, such as algae, fungi, oils and other organic compounds.
- Chloramine reduction, byproducts of water disinfection that can be irritants and cause water quality problems in swimming pools.
- Algae control and microorganisms in swimming pools.
- Preparation for the pool season. It is an option that ensures that the water is clean and safe for bathing after a period of inactivity.
The amount of chlorine used in a shock chlorination process is usually significantly higher than the daily maintenance dose, but this varies depending on the situation and the volume of water to be treated. After shock chlorination, it is important to wait for chlorine levels to return to a safe range, remember to analyze the water.
When should shock chlorination be performed?
Before start the pool season, you can perform shock chlorination to ensure the water is clean and safe.
On the other hand, you can also do it at end of pool season, to prevent the growth of algae and microorganisms during the period of inactivity.
Furthermore, if you suspect or confirm that the water is contaminated with pathogenic microorganisms, such as E. coli, or if you detect a high concentration of chloramines or organic matter, you must perform shock chlorination to eliminate these threats.
Lastly, for disinfect the pool and the water treatment system if it has been exposed to floods.
It is important to follow the chlorine manufacturer's recommendations to ensure that the process is carried out safely and effectively.
How to perform shock chlorination effectively
Performing effective shock chlorination involves a series of important steps to ensure that pathogenic microorganisms are eliminated, contaminants are oxidized, and a safe, clean environment is achieved.
To effectively carry out the shock chlorination, it is essential to follow these steps:
- Pool preparation: Start by cleaning with manual cleaning material basic, both the surface and the bottom, to remove any type of dirt or residue, such as leaves, insects...
- pH adjustment: Make sure it is within the optimal range (7.2 and 7.6). If necessary, perform pH adjustments using products to increase or decrease it. An incorrect pH can affect the effectiveness of chlorine and, therefore, disinfection.
- Chlorine dissolution: The time has come to add chlorine to the pool and to do so you must completely dissolve granular or powder chlorine in a bucket with water and stir it well. Then, distribute this mixture evenly throughout the pool perimeter. If any of the product remains, add more water, mix it again and pour it into the pool. The amount of chlorine needed for shock chlorination is generally in the range of 10 to 15 grams per cubic meter of pool water, the exact amount can be found in the product instructions.
- Water circulation: It is key that you leave the filtration system running in recirculation mode for approximately 2-3 hours. This will allow the chlorine to effectively mix with the rest of the pool water and do its job.
By following these steps, you can make a proper shock chlorination to keep your pool in optimal and safe conditions for swimming.
After shock chlorination
After carrying out shock chlorination, it is important to perform a monitoring to ensure that the pool water or treatment system remains in optimal condition.
Perform regular water tests to measure residual chlorine, pH and alkalinity levels. These tests will help you ensure that your water parameters are within the recommended ranges.
keep a pool cleaning routine. This will help prevent the buildup of organic matter and the formation of algae.
keep the filtration system running for enough hours a day to ensure water is circulated and filtered effectively. This is essential to remove particles and keep the water clean.
From Pools and Products we remind you that the continuous monitoring and maintenance They are essential to keep your pool in optimal conditions and shock chlorination should not be abused.
