Trichloroisocyanuric acid tablet is a new type of high-efficiency bactericidal and disinfecting bleach. Trichloroisocyanuric acid is used in swimming pool disinfection. It has the characteristics of high available chlorine content, high sterilization and bleaching efficiency, stable storage and transportation, convenient use, safety and harmlessness. Sterilization and algae removal tablets have been widely used in the field of swimming pool disinfection.

Trichloroisocyanuric acid for swimming pool water quality treatment

Disinfecting and cleaning swimming pool water has been a headache for many years. If no treatment agent is used, the pool water needs to be replaced frequently, otherwise germs are easy to breed, a layer of slippery and dirty microbial algae adheres to the pool wall, and the pool water will also emit an unpleasant smell. Most swimming pools on the market are currently disinfected with bleach powder Ca (CIO) 2 , but Ca (CIO) 2 is easy to decompose, difficult to store, easy to scale in the wall pool, and acid is often used to adjust the pH value of the pool water. This product has four major advantages:

1. After the release of available chlorine, the remaining cyanurate has a stabilizing effect on the available chlorine in water, and it is non-toxic itself;

2. The chemical effect on swimming pool water is small, reducing the need for regulators of PH value;

3. It has outstanding killing effect on bacteria and algae in the pool;

4. Stable in storage.

Trichloroisocyanuric acid tablets are the most excellent chemicals for swimming pool water treatment. Long-term use can make the pool wall free from algae and make the pool water clear.

How to use: Add 3 to 5 grams of this product per cubic meter of water in the swimming pool every day. If you use a buoy type disinfection block, please follow the method in the buoy instruction manual.

Generally speaking, when adding disinfectant powder to a swimming pool, it is first mixed into an aqueous solution with a small bucket and then sprinkled into the water. At this time, most of the disinfectant powder is not dissolved, and it takes about an hour to disperse into the swimming pool water. Gradually dissolve completely. In order to make the residual chlorine in the swimming pool reach the standard and maintain good water quality more effectively, 1 to 2 grams of disinfectant powder should be added to each cubic meter of water. (1-2kg/1000 cubic meters). After the disinfectant powder is added to the swimming pool, the formula for calculating residual chlorine: (take 1 cubic meter of 2 grams of disinfectant powder as an example, that is, 1000 cubic meters of 2 kg) 2g×90%×1000=1800mg (2 grams of disinfectant powder contains Available chlorine, unit: mg), 1800mg÷1000L (1 cubic) = 1.8mg/L (also known as 1.8ppm), that is to say, if 1 cubic water is added with 2 grams of disinfection powder, if it is not consumed, its theoretical The concentration is: 1.8mg/L. Generally speaking, after adding the disinfectant, the disinfectant will definitely interact with the bacteria and algae in the water (it will also be partially consumed by the organic matter in the water). The water quality of each swimming pool is different, so add After the same amount of disinfectant powder, different swimming pools have different measurable residual chlorine concentrations. If the water quality is good, the residual chlorine should be high, and if the water quality is poor, the residual chlorine should be low.

Precautions for using trichloroisocyanuric acid for swimming pool disinfection

It is a common method to use trichloroisocyanuric acid (TCCA) for swimming pool disinfection. The following are the matters needing attention when using TCCA for swimming pool disinfection:

• Safe use: TCCA is a strong oxidant. When using it, you need to wear personal protective equipment such as protective clothing, gloves, goggles, etc., and avoid direct contact with skin and eyes. At the same time, keep away from fire and heat sources to prevent fire or explosion.

• Appropriate use: When using TCCA for swimming pool disinfection, it should be used according to the dosage in the instruction manual. Do not use excessively, so as not to cause excessive disinfection of water quality or excessive residual chloride content.

• pH value: When using TCCA for swimming pool disinfection, attention should be paid to adjusting the pH value of the swimming pool to the range of 7.2-7.6 to ensure the best disinfection effect of TCCA.

• Avoid mixing: TCCA should not be mixed with other disinfectants to avoid the reaction to produce harmful gases. At the same time, when using TCCA for swimming pool disinfection, care should be taken to avoid pollutants in the swimming pool, and any pollution should be cleaned up in time.

• Storage precautions: When storing TCCA, keep it away from fire sources and flammable items, store it in a dry, ventilated, and light-proof environment, and avoid contact with other items.

• Pay attention to cleaning: After using TCCA to disinfect the swimming pool, the residual TCCA and other pollutants should be cleaned in time to ensure the cleanliness of the swimming pool water quality.

Examples of the use of trichloroisocyanuric acid in swimming pools

Suppose there is an outdoor swimming pool that is used by a large number of swimmers every day. In order to keep the water clean and hygienic, the pool manager decided to use trichloroisocyanuric acid for disinfection.

Based on the size of the swimming pool and water quality requirements, the administrator calculates the required daily dose of trichloroisocyanuric acid. According to the instructions provided by the manufacturer, they learned that the use of 10 grams of trichloroisocyanuric acid per cubic meter of water can effectively disinfect.

The administrators began to use trichloroisocyanuric acid for disinfection. Every morning, inject an appropriate amount of trichloroisocyanuric acid granules into the swimming pool water. The granules dissolve quickly and release active chlorine to kill bacteria. Active chlorine continuously disinfects the water in your swimming pool, keeping it clean and hygienic.

Every week, rangers also conduct water quality tests to ensure the chlorine levels in the water are within safe limits. If necessary, they will supplement the appropriate amount of trichloroisocyanuric acid according to the test results to maintain the ideal state of water quality.

Through the use of trichloroisocyanuric acid, the water quality of the swimming pool has been effectively disinfected and protected, and swimmers can safely enjoy swimming without worrying about the existence of bacteria and viruses.

It is important to note that specific trichloroisocyanuric acid dosage and application methods may vary depending on the size of the swimming pool, water quality requirements and manufacturer's recommended guidelines. In actual application, the relevant instructions and recommendations should be followed according to the specific situation.

In short, when using TCCA for swimming pool disinfection, you need to read the instructions carefully. We provide detailed product instructions, and follow the instructions for use and storage to protect human health and environmental safety. At the same time, it is necessary to regularly test the water quality of the swimming pool to ensure the disinfection effect and the safety of the water quality.
